Hearing loss is a world wide problem

One out of ten people suffer from hearing loss. Usually hearing aids are the number one treatment.

High tech computers
Hearing aid technology is constantly evolving and becoming increasingly advanced. Modern hearing aids are small high-tech computers, being refined and developed to provide better reproduction of natural human hearing. Speech-in-noise test

Treatment of children
Treatment of hearing loss in children is extremely important
Treatment of hearing loss in children is important as a hearing loss affects language and speech development.

Out of the job market
Hearing impaired people are leaving the job market at a much higher rate than their normal-hearing colleagues. Many people find that their hearing loss is a barrier to full participation in the job market as well as their social life. Improved quality of life
Nine in 10 users of hearing aids say their hearing aids improve their quality of life and and their confidence in themselves.

Dangerous ear buds
The small ear buds pose a potential danger to hearing. They can boost the signal by as much as six to nine dB. An individual condition
Tinnitus varies considerably in intensity and type. Some people describe tinnitus as high-frequency whistling sounds while others perceive tinnitus as a buzzing noise or a sound similar to butter sizzling in a frying pan.

Noisy homes
We are continually subjected to noise throughout our lives. We cannot control all noise, but when we return home we can at least shut the front door behind us, and thereby control the noise level ourselves. A magnificant organ
The ear is an advanced and very sensitive organ of the human body. The best way to describe the functioning of the ear is to see the path which the sound waves take on their way through the ear.

Musicians
Millions of music lovers would not contemplate life without their music. However, even more so than their avid listeners, musicians risk their hearing when exposed to loud levels of music for long periods of time.

Hearing Loss Is Common, but Often Untreated

Americans who suffer from hearing loss. They include a third of Americans over 60 and up to half of those over 75, most of whom have age-related hearing loss, a condition known medically as presbycusis. Hearing loss is the third most common chronic condition among older Americans, after hypertension and arthritis. Hearing difficulties in older people can have serious consequences, including social isolation, functional decline and depression. Hearing loss can also impair memory and cognitive function, according to a study by neuroscientists at Brandeis University.

A survey of 2,000 hearing-impaired adults conducted in 1999 by the National Council on Aging found that those using aids had better feelings about themselves, greater independence, improved mental health and better relationships with their families. Yet only one person in five with hearing loss wears a hearing aid — partly because of their cost, which is not covered by Medicare and rarely by private insurance.

Acknowledging the Problem
Some people do not know — or they deny — that they have a hearing problem, complaining instead that everyone seems to mumble or talk too fast. Even those who get a yearly physical rarely have their hearing checked. Others are embarrassed to wear a hearing aid. About 30 percent of people who have hearing aids don’t wear them daily.

Hearing aids have improved vastly in the past decade, in both design and selection. Even so, some people, having once had a bad experience, refuse to explore the many new options.

As with the eye and vision, there are many steps between the ear and hearing, a process that takes but a tiny fraction of a second. Sound entering the ear canal causes the eardrum to vibrate. These vibrations are picked up by three tiny bones in the middle ear that connect the drum to the cochlea, a snail-shell-like structure with three tubes filled with fluid. The resulting waves in the fluid signal hair cells in the cochlea that transmit electrical signals to the auditory nerve that connects to the brain stem. These signals then travel to the brain’s auditory center, where the message is processed.

Disruption or damage at any stage in this chain can result in hearing loss. Among factors that can damage hearing are trauma, chronic infection, wax buildup, fusion of ear bones, diseases like diabetes and medications like the antibiotics vancomycin and gentamicin. Some anticancer drugs are also toxic to the ear. Heredity, too, plays a role; some people carry gene mutations that make them more susceptible to hearing loss.

The most common environmental factor is loud noise, either a sudden very loud noise like an explosion or gunshot next to the ear or, more commonly, repeated exposure to loud noises like those produced by rock bands or earbuds and headphones. Some rockers and countless rock fans have developed hearing problems.

Hearing loss associated with aging most often results from cumulative damage to the hair cells in the cochlea, which, like other body parts, suffer the wear and tear of age. The first to decline are those in the outer part of the cochlea that are sensitive to high-frequency sounds, including those produced by the consonants f, sh, ch, p, s and t, which are crucial to clarity in perceiving speech. The low-frequency vowel sounds are the last to go.

Finding a Solution
Detection of a hearing problem is the first step. Hearing specialists have long urged family physicians to check the hearing of patients over 60 at every annual visit by doing a whisper test in each ear or administering a short written quiz.

Anyone with a suspected hearing problem should be referred to an audiologist for detailed testing, or to an otolaryngologist if the cause is medical. Anyone experiencing sudden loss of hearing in one or both ears should consult an otolaryngologist without delay. That could be a reversible problem if treated quickly.

Audiologists are certified clinicians trained to analyze a hearing problem, prescribe hearing aids and help people adjust to their use. In areas where there is no audiologist, look for a licensed hearing aid specialist who is trained to fit and dispense hearing aids.

Choosing a Hearing Aid

Four styles of aids are now available, ranging in price from about $400 to $3,000:

*  A behind-the-ear model fits over the ear and directs sound into the ear canal through a tube and custom-fitted ear mold. This model offers the most circuit and feature options and is easiest to handle for people with limited dexterity.

*An in-the-ear model fits into the outer ear and projects slightly into the ear canal. It is relatively easy to handle and also supports many features.

* An in-the-canal model protrudes only slightly into the outer ear but can accommodate fewer features and is more difficult to handle.

* A completely-in-the-canal model, the smallest and most difficult to handle, is not noticeable in the outer ear but has the fewest features.

Audiologists can help patients select the most appropriate model based on their hearing and living needs and dexterity. When circumstances change, audiologists can also reprogram hearing aids. New designs help patients distinguish speech in noisy environments; some adjust automatically while others require the user to make adjustments. For people with severe hearing loss who need a lot of amplification, new devices have been designed to suppress the high-pitched whistle that can be produced by a hearing aid turned to high volume amplification.

Most important for anyone getting a hearing aid is to take the time needed to adjust to its use. No hearing aid can replace normal hearing, but when properly fitted and adjusted, an aid can greatly improve quality of life.
