Customer Stories

My mom has been a satisfied patient at Johnson’s since I can remember, so when I finally decided it was time for me to get hearing aids there was no question about where to go. So far I have been pleased too and it’s clear that they truly care about their patients.

Moisture and Hearing Aids

Moisture is the leading cause of hearing aid failure, according to manufacturers. Unfortunately moisture problems are usually not as obvious as droplets visible in the tubing of BTE instruments. Circuitry problems and distortion caused by moisture are actually very difficult to diagnose. However, moisture should not be ruled out when obvious causes such as weak batteries are eliminated or if the problem seems less noticeable in the mornings.

It might be helpful to understand how moisture gets into your hearing aid to begin with. The chief problem is condensation. What causes this condensation? Simply put, warm air holds more moisture and cold air holds less, so moving from a warm environment to a cooler one causes water vapor to condense into water droplets. This is the same condensation effect seen on a cool bathroom mirror after a hot shower. Similarly, entering an air conditioned building on a warm or humid day results in condensation on your hearing aids because the cooler inside air cannot hold as much water vapor. It is important to understand that in most cases you will not see this condensation on your hearing aids and that most problems are caused by the moisture molecules that make up droplets, not the visible droplets themselves. Even though you can’t see the water molecules, you will probably notice their presence because your hearing aids will sound distorted, work intermittently and/or fade in and out, or they will simply stop working.
