Hearing Aid Care

1. The most common reason a hearing aid isn’t working is a dead battery.

Changing your hearing aid battery is easy. Simply refer to your hearing aid user guide supplied with your hearing aid if you need instructions on how to do this. Or click on the image to the left for an online guide.

Size 312 (brown package) lasts between 4-8 days
Size 13 (orange package) lasts between 7-14 days
Size 675 (blue package) lasts between 7-14 days
Size 10 (yellow package) lasts between 2-5 days

2. A blocked wax filter is almost as common as a dead battery.

Your ear canal produces earwax which may clog up the earpiece. Earwax is one of the main causes of problems in hearing aids. To combat this, most hearing aids come with a filter or other device to stop wax getting into the hearing aids. You may not see that the filter is blocked by just looking at it. We recommend replacing the filter if the hearing aid seems weak or is not producing sound.

When you turn on your hearing aids each day, you should listen to the hearing aid immediately to hear the startup chimes. If your hearing aid is not producing startup chimes, even after changing the battery, the hearing aid filter is probably blocked. If you have changed the filter and the hearing aid will still not turn on, the battery may be faulty or there may be a more serious fault with the hearing aid itself. In this case you should contact us for an appointment to inspect the hearing aid.
Use the wax protection system and tools to clean away any accumulated wax each day. Click on the image to see a video of how to replace the wax filter in most Oticon hearing aids.

3. Hearing aid is whistling too much (feedback)

If you are experiencing excessive feedback from the hearing aids (the hearing aids produce squeals and whistling noises throughout the day), there are a number of potential problems underlying this. In no particular order

  1. You may have excessive wax buildup in the ears. This causes sound to be reflected back out towards the hearing aid, resulting in feedback. See your family doctor to get the wax removed safely.
  2. You may not have fully inserted your hearing aids to the right depth. This causes sound to escape from the ear and back towards the hearing aid, resulting in feedback. This guide will help you.
  3. The hearing aid mold is loose. Over time, your ears change shape and grow slightly. If your earmolds are a couple of years old, they may be too loose to maintain the correct seal on your ear. This will result in feedback. Contact us for a new set of molds.
  4. Something is broken on your hearing aid or earmold. Rarely, your hearing aids could have developed a crack or a break in the tubing or even the earmold itself that is allowing sound to escape and cause feedback. Contact us for a repair appointment if that is the place.

4. Water damage usually isn’t permanent.

If your hearing aids have stopped working after they have gotten wet, remove the hearing aids from your ears and remove the battery. Leave the battery drawers open and leave them somewhere safe and dry for a few hours.

You can also place them in a ziplock bag with rice or silica gel desiccant packages (often found in shoe boxes). You can also purchase a hearing aid drying kit which is designed to absorb moisture from the hearing aids.

Most modern hearing aids have an excellent water resistance rating and should recover fully by inserting a new battery once the hearing aid is dry. If not, please contact our office.
