What is a hearing aid? A closer look

What is a hearing aid?


A hearing aid is an electronic, battery-operated device that amplifies and changes sound to allow for improved communication. Hearing aids receive sound through a microphone, which then converts the sound waves to electrical signals. The amplifier increases the loudness of the signals and then sends the sound to the ear through a speaker.

What are the different kinds of hearing aids?

There are several types of hearing aids. Each type offers different advantages, depending on its design, levels of amplification, and size. Before purchasing any hearing aid, it is necessary to ask whether it has a warranty that will allow one to try it out.

There are four basic styles of hearing aids for people with sensorineural hearing loss:
In-the-Ear (ITE) hearing aids fit completely in the outer ear and are used for mild to severe hearing loss. The case, which holds the components, is made of hard plastic. ITE aids can accommodate added technical mechanisms such as a telecoil, a small magnetic coil contained in the hearing aid that improves sound transmission during telephone calls. ITE aids can be damaged by earwax and ear drainage, and their small size can cause adjustment problems and feedback (a whistle sound caused by the fit of the hearing aid or by buildup of earwax or fluid). They are not usually worn by children because the casings need to be replaced as the ear grows.

Behind-the-Ear (BTE)hearing aids are worn behind the ear and are connected to a plastic earmould that fits inside the outer ear. The components are held in a case behind the ear. Sound travels through the earmould into the ear. BTE aids are used by people of all ages for mild to profound hearing loss. Poorly fitting BTE earmoulds may cause feedback.

Canal Aids fit into the ear canal and are available in two sizes. The In-the-Canal (ITC) hearing aid is customised to fit the size and shape of the ear canal and is used for mild or moderately severe hearing loss. A Completely-in-Canal (CIC) hearing aid is largely concealed in the ear canal. Because of their small size, canal aids may be difficult for the user to adjust and remove, and may not be able to hold additional devices, such as a telecoil. Canal aids can also be damaged by earwax and ear drainage. They are not recommended for children.

Body Aids are used by people with profound hearing loss. The aid is attached to a belt or a pocket and connected to the ear by a wire. Because of its large size, it is able to incorporate many signal processing options, but it is usually used only when other types of aids cannot be used.

Do all hearing aids work the same way?

The inside mechanisms of hearing aids vary among devices, even if they are the same style. Three types of circuitry, or electronics, are used:
Analog/Adjustable: The audiologist determines the volume and other specifications one needs in the hearing aid, and then a laboratory builds the aid to meet those specifications. The audiologist retains some flexibility to make adjustments. This type of circuitry is generally the least expensive.
Analog/Programmable: The audiologist uses a computer to programme the hearing aid. The circuitry of analog/programmable hearing aids will accommodate more than one programme or setting. If the aid is equipped with a remote control device, the wearer can change the programme to accommodate a given listening environment. Analog/programmable circuitry can be used in all types of hearing aids.
Digital/Programmable: The audiologist programmes the hearing aid with a computer and can adjust the sound quality and response time on an individual basis. Digital hearing aids use a microphone, receiver, battery, and computer chip. Digital circuitry provides the most flexibility for the audiologist to make adjustments for the hearing aid. Digital circuitry can be used in all types of hearing aids and is typically the most expensive.

What should one expect from hearing aids?

Using hearing aids successfully takes time and patience. Hearing aids will not restore normal hearing or eliminate background noise. Adjusting to a hearing aid is a gradual process that involves learning to listen in a variety of environments and becoming accustomed to hearing different sounds. One should try to become familiar with hearing aids under nonstressful circumstances a few hours at a time. Programmes are available to help users master new listening techniques and develop skills to manage hearing loss.

What questions should one ask before buying them?

Before buying a hearing aid, one should ask the audiologist (technician who tests your hearing with the help of a special equipment) these important questions:
Are there any medical or surgical considerations or corrections for hearing loss?
Which design is best for hearing loss?
What is the total cost of the hearing aid?
Is there a trial period to test the hearing aids? What fees are nonrefundable if they are returned after the trial period?
How long is the warranty? Can it be extended?
Does the warranty cover future maintenance and repairs?
Can the audiologist make adjustments and provide servicing and minor repairs? What instruction does the audiologist provide?

What problems might one experience?

The audiologist will teach one to use and care for the hearing aids. One should be sure to practice putting in and taking out the aids, adjusting volume control, cleaning, identifying right and left aids, and replacing the batteries with the audiologist present.

The hearing aids may be uncomfortable. One should ask the audiologist how long one should wear the hearing aids during the adjustment period. Also, how should one test them in situations where one has problems hearing, and how to adjust the volume and/or programme for sounds that are too loud or too soft.

One’s own voice may sound too loud. This is called the occlusion effect and is very common for new hearing aid users. The audiologist may or may not be able to correct this problem; however, most people get used to it over time. The hearing aid may ‘whistle.’ When this happens, one is experiencing feedback, which is caused by the fit of the hearing aid or by the buildup of earwax or fluid. One needs to see an audiologist for adjustments. One may hear background noise. One needs to keep in mind that a hearing aid does not completely separate the sounds one wants to hear from the ones one do not want to hear, but there may also be a problem with the hearing aid. One needs to discuss this with the audiologist.

Tips for taking care of hearing aids:

The following suggestions will help one care for hearing aids:
Keep hearing aids away from heat and moisture
Replace dead batteries immediately
Clean hearing aids as instructed
Do not use hairspray or other hair care products while wearing hearing aids
Turn off hearing aids when they are not in use
Keep replacement batteries and small aids away from children and pets

What is hearing loss and types

What are the types of hearing loss?

Hearing loss can be divided into 3 categories:

Conductive hearing loss: occurs because of problems in the middle ear. In a normal ear, the sound hits on an intact eardrum (like hitting a dholak). Three small bones work as a lever mechanism to increase the movement, and the third bone (stapes) works as a piston to convey this amplified vibrations to the fluid system of the inner ear. Some mechanical problem, such as fluid in the ear, perforation of the eardrum, or damage to the lever mechanism of the three bones which amplify the sound, or fixity of the eardrum or the bones or piston or new bone formation may result in a hearing loss, where the amplified sound is not reaching the inner ear. However, if the inner ear is stimulated directly by the bone, the nerves, hearing organ and hearing is normal. This is called conductive hearing loss. This is often reversible, and may be corrected by surgery.

Sensory-Neural hearing loss: Here there is a damage to the inner ear (sense organ), or damage to the auditory nerve which conducts the signals to the brain (Neural Hearing Loss) These occur when there is physical or other damage to the end organ or the nerve. Mostly sensory-neural hearing loss is not reversible (except for sudden onset hearing loss due to certain causes). No surgery can correct this loss and a hearing aid is the only solution. Sudden onset sensory-neural hearing loss can be due to a viral infection, or a "mini stroke": blockage of blood supply. This can be reversed by urgent medical management.

Mixed hearing loss: Is a combination of conductive loss, with sensory-neural loss also present. The conductive part may be correctable.

Screening for hearing loss is now recommended in all newborns. In children, hearing problems may cause speech to develop slowly, along with other learning handicaps. By early screening, congenital hearing loss (sensory-neural hearing loss present from birth) can be detected early and suitable measures like Hearing aids, or cochlear implantation can be done at an early age, so that the child does not also become mute. In childhood, ear infections are the most common cause of temporary hearing loss. Fluid can linger in the ear following an ear infection. Although this fluid can go unnoticed, it can cause significant hearing and learning problems. Any fluid that lasts longer than 8-12 weeks is cause for concern, and needs to be treated by a minor surgery to drain the fluid.

What are the causes?
Common causes of hearing loss with type of hearing loss:Genetic: sensori-neuralCongenital or birth defects: sensori-neural, or fixation of the ossicles (conductive)Infections: mainly conductive, maybe sensori-neuralTraumatic: mainly conductive, maybe Sensori-neural (especially bomb blasts)Toxic: sensori-neuralAge-related: sensori-neural (presbiacusis)Occupational: sensori-neuralAny occupation with prolonged exposure to loud noises on a day-to-day basis can result in hearing loss due to nerve end damage.

Temporary hearing loss (Conductive Hearing Loss) can also be caused by:
The build-up of wax in the ear canals (hard wax can cause up to 40% hearing loss)Foreign body lodged in the ear canal Injury to the head Allergy Blocked Eustachian tubes Scarred or perforated eardrum Ear infections, often after a coldReaction to medications such as aminoglycosides, chloroquine, quinidine (sensori-neural)

What are the symptoms?
Signs and symptoms of hearing loss may include:Muffled quality of speech and other sounds Difficulty understanding words, especially against background noise or in a crowd of people Asking others to speak more slowly, clearly and loudly The need to turn up the volume of the television or radio Withdrawal from conversations Avoidance of some social settingsDischarge from ears due to infectionsBlockage of earsBuzzing/ringing sounds in the ears (may feel hearing is normal, but there is a loss at some frequencies)Giddiness/vertigo may be associated with hearing lossPoor academic performance in children without any reasonSpeaking loudly/ or in a very low tone (depending on the cause)

What are the risk factors?
Factors that may damage the inner ear include:Ageing: Presbiacusis. Normally over 60 years, some hearing loss especially at higher frequencies starts. The normal wear and tear of sounds over the years can damage the inner ears cells.

Loud noises: Occupational noise, such as construction or factory work, and recreational noise, such as loud music in concerts, the engine of a snowmobile or motorcycle, airplanes, can contribute to the damage. Sudden Loud noises, like bomb blasts, or even Diwali Crackers, can cause sudden and permanent hearing loss.Heredity: The genetic makeup may make one more susceptible to ear damage. The age related hearing loss may also start earlier.
Medicines: Ototoxicity, drugs such as the antibiotic gentamicin can damage the inner ear. Temporary effects on ones hearing - ringing in the ear or hearing loss can occur if one takes very high doses of aspirin. Some illnesses: Diseases or illnesses that result in high fever, such as meningitis, may damage the cochlea. Viral diseases like mumps, and measles can also result in deafness.For some people, hearing loss may result from a gradual build-up of hard wax, which blocks the ear canal and prevents conduction of sound waves. Wax blockage is one of the most common causes of hearing loss among people of all ages

How is it diagnosed?
To determine ones ability to hear and the extent of hearing loss, the doctor may administer a hearing audiometry test. At first, he may conduct a general screening test to get an overall idea of how well one can hear. He may ask the patient to cover one ear at a time to see how well he hears words spoken at different volumes and how he responds to other sounds. Tuning fork tests are carried out, which indicate the type of deafness and which ear is more affected.
During a more thorough test called audiometry, the patients are asked to wear earphones and hear sounds directed to one ear at a time. The audiologist presents a range of sounds of various tones and asks him to indicate each time he hears the sound. Each tone is repeated at faint levels to find out when the patient can barely hear. This is carried out for both Air Conduction and Bone conduction.
Tympanometry confirms the presence or absence of fluid behind the eardrum, and the normalcy or otherwise of the movement of the eardrum and the ossicles, accoustic reflexes also help in determining the type of hearing loss.
Special Hearing tests, including speech tests and recruitment give an idea if the hearing loss is sensory or neural. BERA (Brain stem evoked Audiometry) shows the normality or otherwise of the hearing nerves, and indicate the site of damage.

The various diagnostic tests include:Audiometry (an electronic hearing test) Speech audiometry with special tests, CT/MRI scan of the head (if a tumour or fracture is suspected) Tympanometry Caloric test/ENGEvoked response audiometry (BERA)

What is the treatment?
The treatment of hearing loss depends on the cause. If hearing loss is due to damage to the inner ear, the only treatment is a hearing aid.

Hearing aids
The doctor can discuss the potential benefits of using a hearing aid. Hearing aids cannot help everyone with hearing loss, but they can improve hearing for many people. The louder sounds help stimulate nerve cells in the cochlea so that one can hear well. Getting used to a hearing aid takes time. The sound one hears is different because it is amplified. One may need to try more than one device to find one that works well. Hearing aids come in a variety of styles. Some hearing aids rest behind the ear with a small tube delivering the amplified sound to the ear canal. Other styles fit in the outer ear or within the ear canal.

Earlier hearing aids used to amplify all frequencies of sounds equally, and often the patient would complain of discomfort, and excessive noise, especially in noisy surroundings like parties or meetings. The newer Digital hearing aids amplify sound according to the frequencies, which are affected, and so are not uncomfortable in these situations. They are computer controlled, and can be adjusted according to the patients individual situations.
If one cannot hear as well as one used to because of wax blockage, the doctor can remove the wax and improve hearing.

The doctor may remove the earwax by loosening the wax. He uses an eyedropper to place a few drops of baby oil, mineral oil or glycerin in the ear to loosen the wax, then squirts warm water into the ear using a bulb syringe. As one tilts the ear, the water drains out. The doctor may need to repeat the process several times before the wax eventually falls out. Alternatively, the doctor may loosen the wax, then scoop it out with a small instrument called a curette. Wax softeners may be needed if the wax is hard and impacted. The doctor may ask the patient to use these drops for a few days at home, and return to suck/syringe out the wax. In case one uses a bud to try and remove this wax at home, it will only result in pushing this hard impacted wax further inside, and cause more pain and blockage, beside making removal more difficult. Some people tend to form hard wax, and need this attention intermittently. For most people, gently cleaning the external part of the ear canal with a bud after using olive oil or substitute is adequate. Do not use sharp instruments to remove wax or foreign bodies

Surgery for deafness
Myringoplasty, Tympanoplasty, Ossiculoplasty and Mastoidectomy. Stapedectomy: If there is a perforation in the eardrum, it can be repaired by a minor surgery. One takes the Donor graft from either behind the ear (Temporalis Fascia), or from the soft part in front of the ear (Tragal perichondrium), and by either working through the ear canal, or by making a cut behind the ear (depending on training and expertise). The surgeon repairs the eardrum (Myringoplasty). If the lever mechanism (3 bones) is also damaged, this is repaired by using either cartilage, or bone, or an artificial prosthesis (Tympanoplasty/Osiculoplasty). If the bone behind the ear is also destroyed, and there is danger of the infection spreading to the brain, or affecting the nerves, then a more serious surgery, Mastoidectomy, needs to be done where all the diseased bone is cleaned. In case the last lever bone, which is the piston (Stapes), is fixed by new bone formation, a very delicate surgery, Stapedectomy is needed, but there is a small risk of causing further damage to hearing in this surgery.

Cochlear implants
In case there is no useful hearing, even with the best hearing aids, and especially where the hearing has been lost after speech development is complete, cochlear implantation can be considered. In this surgery, electrodes are inserted into the inner ear, and the hearing aid (speech processor) fitted behind the ear thus sends electrical signals straight to the hearing nerves. This is not suitable if the nerve itself is damaged. The implant is very expensive (the whole process costing a few lakh rupees) and has its own share of complications. It should only be considered in the specific indications.

Cell phones can cause another kind of ringing

Regular cell phone use may increase the risk of developing persistent ringing in the ear - a condition known as tinnitus.

Tinnitus is often described as ringing in the ears. It may also be described as the sound of hissing, escaping air, running water, whistling, buzzing, or humming noise. While tinnitus can be associated with diseases and disorders of the ear, brain of blood vessels, there are few known risk factors for tinnitus. There has been no systematic study to link mobile phone use and tinnitus earlier.

To investigate the association between tinnitus and mobile phone use, researchers studied 100 people of Austria treated for chronic tinnitus and 100 healthy controls. The participants were asked a variety of questions about their cell phone usage.

Based on the participants' responses, it was found that participants who used a cell phone before the first symptoms of tinnitus appeared were 37 percent more likely to develop the condition than those in the control group. Also, people who used their cell phone for at least 10 minutes a day were 71 percent more likely to develop tinnitus as compared to other study participants. Most people in the study used their cell phones on both ears, but tinnitus typically affected one ear - 38 percent of participants mentioned the left ear and about the same percentage said it distressed them most of the time. Twenty-nine percent reported also suffering from vertigo, or dizziness.

Loud noise is the main risk factor for tinnitus. High intensity, long duration of mobile phone use is likely to be associated with occurrence of tinnitus, as a high amount of microwave energy is absorbed by the cochlea in the inner ear during cell phone use, and this might explain the possible connection.

Though this study shows a relationship between tinnitus and cell phone use, a much larger study would be needed to determine whether cell phones really cause tinnitus.

What is tinnitus?

What is tinnitus?

Tinnitus is often described as ringing in the ears. It may also be described as the sound of hissing, escaping air, running water, whistling, buzzing, or humming noise.

What is the cause?

The exact cause of tinnitus is not known. Problems that can cause tinnitus or make it worse are wax buildup or foreign objects in the ear canal, ear or sinus infections, ear, head, or neck injury, otosclerosis (which is growth of the bone surrounding the middle and inner ear), exposure to loud noise or hearing loss due to aging. It could also be due to diseases of the central nervous system such as multiple sclerosis, tumours, depression and stress and thyroid disorders.

What is the diagnosis?

The doctor asks about symptoms and does an examination. Depending on the symptoms, the following tests may be done - hearing test, X-ray of the head, an angiography (blood vessel studies), CT or MRI scan of the head.

How is it treated?

Tinnitus usually lessens or goes away with time. If it persists, the following treatments are recommend -
Medicines, including anti-anxiety drugs and antidepressants, which can help adjust to the irritation of the tinnitus.
Medicines, including antihistamines, anticonvulsants, an anaesthetics.
Tinnitus retraining therapy (TRT), which combines low-level, steady background sounds with counselling. This combination helps grow unaware of the sounds of tinnitus.
Hearing aids for hearing loss
Biofeedback, which is a relaxation technique that teaches one to control certain body functions such as pulse, muscle tension, and brain wave activity.

What is the prevention?

The common cause of tinnitus can be avoided by staying away from loud noises. One can try using ear protectors if in a noisy environment.

What are Hearing Aids?

What are Hearing Aids?
A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations.
A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.

Types of Hearing Aids :
  1. Digital Hearing Aid
  2. Programmable Hearing Aid
  3. Conventional Hearing Aid

Hearing Loss Among a Younger Generation

Hearing Loss Among a Younger Generation

When you're young, losing your hearing isn't one of your top concerns. But according to www.youth.hear-it.org, more and more young people are developing hearing problems.

While hearing loss is most often attributed to heredity or aging, things like concerts and listening to music on headsets at loud settings can often be the cause of hearing loss in a younger person. The younger generation tends to turn things up louder just for the fun of it, not because they are hard of hearing.

Living in a big city and being constantly exposed to excessive traffic noise—at a close distance—can also be a source of gradual hearing loss. According to a recent study performed by the Society to Aid the Hearing Impaired and published in the Times of India, roughly 74 percent of traffic patrol officers in Hyderabad, India, are suffering from hearing loss. Although this loss of hearing is a result of working long hours at an extremely close range to the major noise levels of a city, it’s important to keep in mind the external factors that may surround a young person in their own life.

What are Some Warning Signs?
“This age group may notice a temporary hearing threshold shift or tinnitus (ringing in the ears) after attending a loud concert or turning their MP3s up too loud,” said Dr. Mary Jane Garnett, an audiologist at the Hearing Services of Antioch, California.

There are warning signs to look out for if someone thinks they might be experiencing hearing loss at a young age. These include experiencing a ringing or buzzing sound inside the ears (especially after a loud concert,) pain inside the ears or even an increased sensitivity to noise. Experiencing any of these warning signs should be a trigger to visit a doctor and request a hearing test.


What Can I Do to Protect My Hearing?
Young people should take action if they suspect they may be losing their hearing by having a comprehensive hearing test as soon as possible. Not only will it help diagnose the problem, but it will be a good reference point for future tests.

If a doctor recommends a hearing aid, there's no cause for alarm. Hearing aids have evolved dramatically over the years and new technology has allowed them to be small and nearly unrecognizable to another person.

Young adults can start taking proactive measures to avoid hearing loss, such as listening to music at a lower volume, or wearing ear plugs to concerts or other loud venues. They may think their hearing problem can be solved with a quick turn of the volume, but if they don’t take care of it now, it could affect them more severely in the future.

Software Runs Hearing Systems

Hearing systems or "hearing aids" have been computerized and can be programmed to a person's individual lifestyle.

A "hearing system" means that you have a digital hearing aid. Digital hearing aids also have a "volume control" switch that can be set easily by pressing the switch. They also have a toggle switch that allows you to switch back and forth from automatic mode and mute mode.

The best way to use your hearing system is to let the programs automatically select the appropriate hearing program for each different hearing situation. The software will automatically adjust the volume up or down 2 or 3 decibels.

Your hearing care professional can print your complete set up, along with directions on how to use all the features.

Hearing care professionals can also individualize hearing programs for specific purposes. An example would be FM wireless communication (using a cell phone).

A Telecoil or T-coil is a type of wire that you wear around your neck to use with specialized telephones, and/or inductive loop systems. Inductive loop systems are wires that have been installed in a pattern to enclose a room or building. You can find them installed in some churches, schools and theaters.

Another option is a type of magnet that attaches to the handset of your telephone and automatically triggers the telephone program. When you finish talking, the telephone program is turned off and the system returns to the previous program.


Are you a music lover? A music program can be downloaded into your system that you turn on and off with the touch of a button. The music setting allows more of the background noise to come through. Normally, most of this is minimized or filtered out.

Golfers may have problems with wind noise; this too can be filtered out.

A remote control can be programmed to adjust the volume, turn on/off individual programs and FM mode. If you have two hearing aids, the remote control will adjust both at the same time. A person might use a remote if they are uncomfortable changing settings by hand.

Choosing the best hearing aid

Choosing the best hearing aid is like choosing any product - it's a matter of weighing the pros and cons of the many hearing aids on the market.

Choosing the best hearing aid is like choosing the best car, refrigerator or stereo; it's about choosing the device that most suits the patient's needs. Thanks to new developments in hearing aid technology, smaller and less obvious hearing aids now pack even more power into their tiny equipment. Digital technology offers the ability to amplify quiet sounds without distorting loud sounds, making it easier for patients to hear everyday conversations, enjoy music and participate in every day events.

 One important thing to note is that while Medicare does not cover the cost of hearing aids, many private insurers do. The cost of a hearing aid typically includes a 30-45 day "adjustment period" in which patients can return to their audiologist for adjustments to the device. Hearing aids may be returned during this time or patients can request adjustments to the hearing aid. Even if patients return a hearing aid during this time period, they can still be billed for the fitting or initial visit.


Choosing the Best Hearing Aid
When evaluating the various hearing aid options, consider the pros and cons of each.

Battery life: In general, the smaller hearing aids that fit into the ear have the shortest battery life. For some patients, hiding the hearing aid in the ear canal outweighs the annoyance of changing batteries frequently. Other patients may consider the battery life of hearings aids more important and choose another larger model with a proportionately larger battery that needs less frequently updates.
Size: Size matters in terms of hearing aids. Smaller hearing aids may provide less amplification of sounds. It's important to consult with an audiologist, a specialist in hearing, to discover the best hearing aid options for a particular patient's circumstances.
Cost: Medicare doesn't cover the cost of hearing aids, but private insurance might, so check plans carefully. Some audiologists offer payment plans.
Hearing Aid Basics for Comparison Shopping
To truly evaluate the costs and benefits of various hearing aids, as well as weed our misleading claims, consider the following:


Warranty: A good warranty covers parts, maintenance and repairs for a specific time period. Check and compare warranty claims among various hearing aid brands.
Claims: If a hearing aid company claims it can fully restore hearing, be skeptical. While hearing aids can greatly help hearing loss and uncover many lost sounds, they cannot restore perfect hearing.
One-size-fits-all: Like eyeglasses, one type of hearing aid won't work for everyone. Only an audiologist can examine the patient's hearing and recommend specific types of hearing aids to correct for hearing loss. Just as an optometrist doesn't prescribe the exact same lenses to every patient with nearsightedness, so too will an audiologist recommend different options depending upon the patient's hearing loss.
Adjusting to a Hearing Aid
Even the best hearing aids require an adjustment period. The National Institute of Deafness cautions patients to expect certain things: their own voices may sound too loud, a whistling sound may be noted, or some sounds may be too loud or too soft. While an audiologist may be able to adjust the hearing aid to compensate for this, some problems may be inevitable. Patients are advised to be patient and try to get used to their new hearing aids.

Hearing aids can open up a world that was once closed to patients by introducing sound into their lives. They can improve the quality of life for senior citizens and help many participate in normal daily life, making everything from trips to the grocery store to church meetings easier to navigate. When choosing the best hearing aids, be sure to evaluate and comparison shop, working with an audiologist to discover truly what's the best hearing aid to improve hearing loss.

Baby Boomers' Hearing Loss Hip Cute Hearing Aids

Baby Boomers were raised on Rock & Roll. New hearing aids are virtually invisible or made to look like jewelry. Other new styles work with Bluetooth technology.

Baby Boomers are starting to experience hearing loss. After years of cranking up Layla, Brown Sugar, and U2, is it any wonder? Fortunately, the marketplace has responded with invisible, open ear, and Bluetooth hearing aids.

Baby Boomers and Hearing Loss
Well, hip music-loving Boomers have always known that hearing loss will catch up with them eventually. There is just no way that a Boomer Chick or Boomer Dude could stand that close to those huge pounding speakers and have fans screaming next to their ears without some kind of sacrifice. Yes, those Rolling Stones’ concerts were worth it, but now it’s time to face the music.

Baby Boomer Trends
Hearing loss is nothing new to rockers, as well as music fans.

Pete Townshend, from The Who, has severe hearing damage and tinnitus (ringing in the ears) which causes him pain.
Neil Young, from Crosby, Stills, Nash, & Young, went acoustic in the 90s because of damaged hearing.
Bono, from U2, actually got his nickname from a hearing-aid store in Dublin called Bonavox Hearing Aids.
A few others are Sting, Ted Nugent, Phil Collins, Cher, Mick Fleetwood, Bob Seger, Jeff Beck, Peter Frampton (from his wawa pedal), Bob Dylan, and the late George Harrison.

Hearing Aid Hipness
While price is always a consideration when buying a hearing aid, a more important factor for Baby Boomers is that they never look like "seniors" and are never called "seniors". So, hearing-aid companies are responding in three ways, by making newer models:

Smaller and more invisible
Hipper looking
Available with Bluetooth technology
Digital Hearing Aids
Quick, what kind of hearing aid does Bill Clinton wear? Who knows? He started wearing hearing aids in both ears when he was 51 (1997), but they were CIC hearing aids (Completely In Canal) so few people knew of his significant hearing loss during his presidency.

Modern hearing aids are small and effective "mini ear computers” and are similar to something Steve Austin “The Six Million Dollar Man” would have worn. Boomers, with CIC aids, should think of themselves as first generation Cyborgs (cybernetic organisms).

Digital hearing aids can adapt to the preferences of the wearer. When environmental sound becomes too loud, the volume automatically adjusts. When sounds are too soft, they are cranked up a notch.

Pros of CIC Hearing Aids:

Reduced distortion and acoustic feedback
Increased comfort
Cosmetically superior
Cons of CIC Hearing Aids:

Cost
No manual volume button
Extra maintenance problems
Hip Open Ear Hearing Aids
Not all hearing aids look like a grandchild has stuffed Silly Putty into the ears. Some "aural accessories", like the Siemens Vibe have become fashion statements.

The Vibe comes in leopard or racing-flag checks and sits in the crest of the ear, where it can be seen, leaving the ear canal unblocked. This device looks like the user has adopted a trendy new style of ear piercing.

The Vibe has cool technology to:

Minimize irritating noise (papers rustling, pots and pans banging)
Block feedback
Change microphone placement (Sound directionality uses the ear’s natural funnel shape.)
Siemens is not the only company to come out with cool hip “sonic perception upgrade devices”, so look around for other kinds of attractive gadgets. There are lots of options.

Bluetooth Hearing Aids
Bluetooth is a short-distance wireless technology. The Bluetooth headset/earphones are those devices that many young people stick on their ears so they can talk on the phone wherever they go.

Now, hearing aids work with Bluetooth or look similar to Bluetooth headsets. Instead of making these hearing aids smaller and less visible, the idea is to make the wearer look like a young techno-savvy hipster.

There is no shame in rocking Boomer Chicks or Boomer Dudes admitting to hearing loss. Noise-induced sensory recession can be caused by many loud sounds, but rock music is a likely culprit. Thankfully, Baby Boomers make up a big market and have inspired a new wave of hearing-aid design.

Cochlear Implant for Sensorineural Deafness

A cochlear implant can be a helpful aid for sensorineural hearing loss in children and adults. This article describes how normal hearing and implants work.

What might seem like a simple process – the hearing of a sound – is dependent on the proper functioning of a complex sequence of events. A problem with any step in this sequence can lead to hearing loss.

How Does the Ear Work?
In the outer ear, sound is collected in the auricle (the external part of the ear) and funnelled down the ear canal to the eardrum.
In the middle ear, a chain of tiny bones (or ossicles) transmits vibrations in the eardrum to the inner ear.
In the inner ear, the vibrations transmitted by the ossicles cause movements in the fluid that fills a cavity called the cochlea. The cochlea is lined with ‘hair cells’ bearing flexible protein filaments, and movements in the fluid cause the filaments to bend. The bending stimulates the hair cells and this in turn stimulates the cochlear nerve, which carries information about the sound that was heard to the brain, for processing.
Sensorineural Hearing Loss and Cochlear Implants
Loss of hearing can stem from problems at any point in this sequence. Sensorineural hearing loss is caused by abnormalities in the hair cells that prevent them transmitting normally to the cochlear nerve. These abnormalities can be present at birth, or may be caused by drugs, infection or prolonged exposure to very loud noise.

Sensorineural hearing loss may be overcome with a hearing aid, which amplifies the sounds that enter the outer ear. However, people with hair cell damage often find it difficult to distinguish between different sounds – including speech – and simply increasing the volume of those sounds does not solve the problem. For these people, a cochlear implant (sometimes called a 'bionic ear') may help.

Cochlear implants are used both in children born with sensorineural deafness and in people who have developed the condition later in life.

How Does a Cochlear Implant Work?
Cochlear implants take the place of the damaged hair cells by directly stimulating the cochlear nerve.

A microphone worn behind the ear picks up sounds, converts them to an electrical signal and transmits this to a processor. The processor may be also be positioned behind the ear, or may be carried in a pocket or on a belt.
The processor organizes and filters the signal, then sends it to a transmitter in the form of radio waves. The transmitter is worn on the side of the head, held in place by a magnet.
Under the skin, implanted into the bone directly beneath the transmitter, is a second magnet together with a receiver/stimulator. The receiver/stimulator picks up the radio signal from the transmitter and passes this down a thin wire that has been threaded into the cochlea.
Electrodes on the wire stimulate the cochlear nerve as would healthy hair cells.
Cochlear Implant Procedure
Cochlear implant surgery is performed with a general anaesthetic and normally takes around two hours. To fit the internal parts of the device, the surgeon makes an incision in the skin behind the ear for the receiver/stimulator, then cuts through the skull and into the inner ear to position the electrode wire.


The patient can usually return home the same day, but the implant is not switched on for up to a month after the surgery. An extended period of training follows, during which the patient learns how to interpret the sounds that he or she hears through the implant.

In 2003, a study suggested that children with a cochlear implant were at increased risk of bacterial meningitis compared with children of similar age in the general population (Reefhuis J et al. N Engl J Med 2003; 349: 435–45). The risk was greatest in those with a particular type of implant. This implant was quickly withdrawn from the market, but the Centers for Disease Control and Prevention have issued recommendations for children with any implant type.

Cochlear implants are thought to be more effective the earlier they are fitted, raising ethical concerns about performing invasive surgery on very young children. For those who do not consider deafness to be a disability that needs to be "cured", cochlear implants are a sensitive issue concerning identity and self-image.

Benefits and Limitations of Cochlear Implants
A cochlear implant does not restore normal hearing, but it allows users to recognize important sounds such as alarms and warnings, and may help with the understanding of speech. Anyone referred to a cochlear implant centre can expect a thorough assessment of their suitability for an implant, as well as advice on the risks and benefits, before any decisions are made.

Deafness and hearing loss

Deafness and hearing loss are not uncommon among people over 50, or even younger. Today's hearing solutions are affordable, comfortable and highly technical.

The Hearing Problem
More baby boomers are facing hearing loss issues than any other generation, if you believe reports in print and electronic media. Boomers reaching their 50s and 60s deal with typical age-related hearing loss, but many also suffer consequences of having been the first teens to latch onto ear-splitting rock music.

Earbuds, headphones and concerts may be contributors. But no matter the reasons, this generation, with wide-spread hearing concerns, is failing to do something about it, says a recent report from ABC News in Denver.


Quoting a Harris poll for Cochlear Americas, the report says hearing loss has a profound impact on quality-of-life. For instance, both women and men become annoyed or impatient with people who appear to not be listening. Those non-listeners are often hearing impaired and undiagnosed.

Relationships, says the study, can be adversely affected. Hearing loss is known to create depression and isolation. It can be dangerous – you can’t hear oncoming traffic, for example. Even so, the poll says 57% of men and 37% of women have not sought treatment or evaluation.

How You Can Manage Your Hearing]
The process, the road to better hearing at any age, is painless and convenient. There are remedies and treatments to fit almost any budget and lifestyle.

Today’s high-tech hearing instruments can talk to each other and self adjust to filter out annoying background noise. Some have as many as a million computer-connected adjustments to customize your hearing experience and specifically suit your particular loss.


Your grandparents may have worn bulky blobs of brittle plastic visible from a block away. Their hearing aids had cords winding through their clothing to a little pouch pinned to undershirt or bra. Adjustments consisted of on, off and loud whistling.

Now, instruments like Centra Active come with remote control that allows digital volume adjustments. You may choose from three custom designed hearing programs programmed into your aids. Like music and TV? The aids can be programmed to enhance that sound. Work in a noisy environment where you have to sort conversation from background junk? No problem.

These talented hearing aids smooth sound so harsh noise like breaking glass or running water don’t cause discomfort. Siemens, for example, has perfected data learning, allowing a pair of hearing aids to adjust based on your preferences. Can you imagine ear-to-ear communication that auto-balances your hearing? How about automatic wind screening so you don’t get whistles and screeches from brisk wind?

Your audiologist can, and should, interview you about lifestyle and environment in order to monitor the settings that will work best for you. Fittings aren’t about size and style as much as they’re about meetings with the audiologist. You’ll discuss what’s working for you and what needs tweaking. You’ll explore the benefits your insurance company may or may not provide. She should also do a complete preliminary workup and a series of hearing tests to determine your exact needs. Those screenings and subsequent fittings should be included in the price you pay.

How the Technology Works
Here are a few digital innovations that make hearing today’s hearing aids far superior to yesterday’s clunkers:

Reduction of low level background noise and microphone sounds.
Feedback reduction or elimination.
Improved speech recognition.
Digital speech enhancement (DSE) – relatively new, but thought to increase intensity of some speech components.
Directional microphones that can switch between directional and multi- or omni-directional modes, so you can determine where sound is coming from.
Rechargeable batteries.
Transmitters that fit right into your ear canal, making the aids practically invisible and so comfortable you’ll forget you’re wearing them.
Granted, the new digital aids, almost bionic in their intuitiveness, can be pricey – as much as $12,000. But as incredible as high end technology like Siemens’ Centra Active is, prices for good quality hearing aids begin much more reasonably than that and lower to mid-end aids can be just as life-altering for many patients.
