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 a hearing aid is termed digital, it generally means the hearing aid uses 100% digital processing. 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 hearing aid specialist 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 is a natural part of the aging process. Hearing challenges can begin to present themselves based upon your hearing health history, including exposure to loud noise, certain medications, infections, head or ear trauma, congenital (birth or prenatal) or hereditary factors, as well as a number of other causes.
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.
There are essentially three levels of hearing aid technology. We refer to these as analog, digitally programmable, and digital.
ALDs can increase the loudness of desired sounds, such as a radio, television, or a public speaker, without increasing the loudness of the background noises.
There are many assistive listening devices available today, from sophisticated systems used in theaters and auditoriums to small personal systems.
There are many styles of hearing aids. The degree of the hearing loss, power and options required, manual dexterity abilities, cost factors, and cosmetic concerns are some of the factors that will determine the style the patient will use.
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.
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.
