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.

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”.

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

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.

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.

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.

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

People with all degrees and types of hearing loss — even people with normal hearing can benefit from assistive listening devices.

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.

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.

Auditory Processing (also called Central Auditory Processing) refers to the means by which we make sense of what we hear. “Auditory Processing Disorders” refers to the abnormal interaction of hearing, neural transmission and the brain’s ability to make sense of sound.

The hearing aid specialist has training in the assessment of patients who specifically seek rehabilitation for hearing loss.

Hearing aids work very well when fit and adjusted appropriately. They are designed to make words and the conversations easier to understand in all situations, without making sounds appear to be too loud.

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