At Welsch Hearing Aid Company, we believe that the most important part of purchasing and wearing a hearing aid is preventive maintenance and service. That is why we have a fully equipped service lab. Since hearing aids are worn partially or completely inside the ear it is subject to your body chemistry. Oils, sweat, moisture, dead skin cells and ear wax which can cause hearing aids to fail. Even though hearing aids are moisture resistant through nano-coating, corrosion and deterioration of components can still occur. In addition, microphones and receiver (speaker) can get plugged with debris.
In our lab, you will also find our Video-Otoscope. When you come in for your hearing aid cleaning we also check your ears. If they need a good cleaning we will tell you to get your ears cleaned. Keeping your ears clean is a must if you don’t want to plug your hearing aids up with dead skin and ear wax.
Once we disinfect your hearing aids we vacuum them. Our hearing aid vacuum system has a needle vac which we use to suction debris out of the microphone, receiver ports and battery compartment. Quite often, with this equipment we can bring “dead” hearing aids back to life. In addition to vacuuming the hearing aids, we use fine metallic picks to remove earwax and other debris that cannot budge with only the vacuuming. After that we place the hearing aid in a vacuum chamber to take moisture out of the hearing aids. We also change the tubing in the behind-the-ear hearing
aids. Many years ago, it was discovered by Starkey Hearing that the diaphragm of the receiver gets out of alignment over time causing distortion. When it is place in a vacuum chamber, the diaphragm realigns, causing the distortion to go away. Even if the hearing aids are not dirty or full of moisture, the hearing aids sound clearer after being in the vacuum chamber for even a few minutes.
We also have a Red Wing Motor and a Brasler dental drill, both of which we use for custom earmold and hearing aid modifications. Susan loves modifying an earmold or hearing aid to fit better. So if your hearing aid or earmold is making your ear sore, bring it in to Susan and let her see what she needs to grind and buff for a better fit. Unfortunately, since the majority of the hearing aid manufacturers use laser technology to make the custom hearing aids the material is much thinner than it used to be, making it more difficult to modify them.
Sometimes cleaning and modifications may not always solve the problem. In that case the hearing aid may have to go into the manufacturer for repair.
