Hearing Aid Information

Hearing aids are a device used to assist individuals with a hearing impairment in their everyday lives with things such as going to a meeting, attending church or meeting with friends for coffee. Hearing aids come in all shapes and sizes. Some hearing aids fit inside of the ear canal, whereas others are worn on top of the ear with a thin clear tube running toward the ear canal. The type of hearing aid applicable to each person differs greatly, depending upon lifestyle, preference, hearing loss and financial coverage. Almost all hearing aids are powered by 1.4 volt hearing aid batteries, these batteries can be rechargeable or disposable. The difference in price between rechargeable hearing aid batteries and disposable hearing aid batteries is very insignificant over the life of your hearing aids. Hearing aid batteries come in four different sizes: Size 10, Size 13, Size 312 and Size 675. The size of battery used depends on the type of hearing aid you have. It is important to use high quality hearing aid batteries to power your hearing aids because this ensures steady performance and optimal sound. Zinc air hearing aid batteries are the latest in hearing aid battery technology. Additional perks of zinc air hearing aid batteries, such as those produced by Rayovac, are that they are made in the USA and are mercury free. Hearing aids can never bring back normal hearing. The goal of the use of hearing aids is to achieve as close to regular hearing as possible. Hearing aid technology is constantly improving and it is the job of your local audiologist to keep up with these changes and be knowledgeable about which type of hearing aid will best fit your needs.

Hearing aids are usually dispensed with three accessories: dry aid kits, battery testers and hearing aid cleaning tools.

Dry Aid Kits
Moisture is hard on all hearing aids. Dampness, humidity and body moisture reduce their sensitivity, shorten battery life and cause corrosion. Under extremely moist conditions, the sensitive hearing aid microphone and receiver may become inoperable.

Battery Testers
Hearing aid battery testers are able to check all sizes of hearing aid battery cells. Testers will indicate if the battery is good or bad. These testers are offered in many convenient sizes and some even include replacement battery compartments.

Hearing Aid Cleaning Tools

Wax Remover Tool
A thin wire loop pulls out wax which accumulates in the receiver opening of the hearing aid. Some hearing aid wax removal tools come with a magnet which is located on the handle. This magnet is used for removing and installing batteries in all types of ITE, BTE and CIC hearing instruments and can be helpful for patients with dexterity problems.

Mini Brush
A small all-purpose brush used for removing foreign matter in and around the microphone opening.

Vent Pick
A very thin stick-like tool (or brush) used for removing wax and other debris from hearing aid vents.
