Hearing Aid Care

Hearing aids are delicate (and very expensive!) instruments. Within their tiny, fragile cases, they pack an enormous amount of highly sensitive, sophisticated electronic circuitry. Unlike eyeglasses, hearing aids need regular upkeep and a lot of tender loving care to ensure continued optimal performance. With reasonable care, the life expectancy of a hearing aid is about three to five years; with care and attention to maintenance, that lifetime may be extended.

Protection And Storage

There are some things hearing aids do not like: shock, temperature extremes, and moisture. Shock: Trauma to the hearing aid caused by being dropped or roughly handled, or parked temporarily on undesirable spots of high or low temperatures such as radiators or air conditioners. Dogs love to chew on hearing aids. Babies also find them attractive, sometimes edible. Any of these can be devastating to the proper functioning of a hearing aid (not to mention the baby!) .

Some Preventive Measures

Provide proper storage for your hearing aid whenever it is not in your ear. Set aside a good place, protected from danger of being knocked off a table or picked up, or subjected to the teeth treatment of a pet or child. A box in a drawer by your bed is a good place and is handy when you rise or retire.

Temperature Extremes

Damage incurred from high heat or cold, which may adversely affect a hearing aid’s performance. Much of this damage is caused by the changes in temperature, which causes a condensation of moisture within the aid, rather than the temperature itself. This change can occur many times a day, as someone goes from hot to air-conditioned comfort and back again. High humidity and perspiration exacerbate this problem. Some preventative measures: Never leave a hearing aid on a radiator or an air conditioner, near a stove, in a sunny window, in the glove compartment of a car on a hot day, or in any other extremely hot or cold place. Do not try to dry the hearing aid in an oven or clothes dryer, or wear it while using a hair dryer or tanning under a sun lamp.


Anything wet, high humidity, perspiration, condensation, accidental immersion in a bath or pool can cause damage to a hearing aid and prevent it from functioning properly. Keep your hearing aid dry. An exception may be made for the few hearing aid models recently marketed as being specifically designed as water resistant. If you are interested in this type, ask your hearing aid dispenser. Some preventative measures: If you live in an area subject to high humidity or regularly engage in perspiration-inducing activities, consider buying some sort of DRI-AID kit. This is a small, inexpensive kit consisting of silica (desiccating) crystals in a jar. At night, after removing the battery, place the hearing aid down in the jar. During the night, the moisture in the hearing aid will be absorbed by crystals. The silica crystals can be recycled by oven heating when they become moist (indicated by change in color), so the kit has a long life.

Earmolds And Tubing For BTE(Behind The Ear)

Keep earmolds clean. If the sound bore seems clogged with wax, clean it gently with a pin, wire-loop, or toothpick. At regular intervals, remove the earmold from hearing aid .
