Virtually all patients wearing hearing aids complain about background noise at one time or another. There is no way to completely eliminate background noise.

The term DIGITAL is used so often today, it can be confusing. When the term “digital” is used while referring to hearing aids, it generally means the hearing aid is 100% digital. In other words, the hearing aid is indeed a “complete computer”.

All custom made hearing aids and earmolds are made from a “cast” of the ear. The cast is referred to as an ear impression. The audiologist makes the ear impression in the office. It takes about 10 to 15 minutes.

All batteries are toxic and dangerous if swallowed. Keep all batteries (and hearing aids) away from children and pets. If anyone swallows a battery it is a medical emergency and the individual needs to see a physician immediately.

Hearing loss occurs to most people as they age. Hearing loss can be due to the aging process, exposure to loud noise, certain medications, infections, head or ear trauma, congenital (birth or prenatal) or hereditary factors, diseases, as well as a number of other causes.

Middle ear implants are surgically implanted devices. The FDA has approved specific middle ear implants and the FDA is still reviewing others. The middle ear implant is a useful hearing instrument and is quite different from traditional hearing aids.

Hearing aids work very well when fit and adjusted appropriately. They amplify sound! You might find that you like one hearing aid better than the other. The left and right hearing aids will probably not fit exactly the same and they probably won’t sound exactly the same.

There are essentially three levels of hearing aid technology. We refer to these as analog, digitally programmable, and digital.

Tinnitus is an abnormal perception of a sound which is reported by patients that is unrelated to an external source of stimulation. Tinnitus is a very common disorder.

Results of the audiometric evaluation are plotted on a chart called an audiogram. Loudness is plotted from top to bottom. Frequency, from low to high, is plotted from left to right.

There are many styles of hearing aids. The degree of the hearing loss, power and options requirements, manual dexterity abilities, cost factors, and cosmetic concerns are some of the factors that will determine the style the patient will use.

You may have certain communication needs that cannot be solved by the use of hearing aids alone. These situations may involve the use of the telephone, radio, television, and the inability to hear the door chime, telephone bell, and alarm clock.

No. People with all degrees and types of hearing loss — even people with normal hearing can benefit from assistive listening devices.

There are many assistive listening devices available today, from sophisticated systems used in theaters and auditoriums to small personal systems.

Tinnitus is the term for the perception of sound when no external sound is present. It is often referred to as “ringing in the ears,” although some people hear hissing, roaring, whistling, chirping, or clicking.

Tinnitus may originate from various lesions and from different sites. The auditory system involves highly complicated inner ear structures, many afferent and efferent nerve pathways and a great amount of nuclei that form a complex meshwork.

Five thousand children are born profoundly deaf each year in the United States alone. Another 10 to 15 percent of newborns have a partial hearing handicap.

When Geoff Plant asked me to give this keynote presentation, he said to be sure that I included some of my personal experiences as a hard of hearing person.
