Distorted sound is one of many hearing aid issues that you may need to troubleshoot, but following these simple steps could save you a trip to the hearing center. Distorted sound is often described as sounds that seem to be vibrating to where it sounds like everything or only certain sounds are going through a fan before reaching your ears.

If you’re experiencing distorted sound, here are some troubleshooting steps you can take:

  1. Check the batteries for corrosion.

One of the most common problems that leads to distorted sound in hearing aids is a bad connection with the batteries. If they have become corroded for some reason, this is likely to be the root of the problem. Pull the hearing aid battery out of its compartment and look to see if there are any signs of corrosion. If there are, then throw it away and check the compartment for residue from the corrosion. If the inside of the hearing aid looks untouched, then you can go ahead and put in a new battery.

If the inside of the hearing aid shows signs of corrosion, you’ll need to very carefully clean it out to remove any and all residue from the inside. You may need to use a small amount of white vinegar on your hearing aid cleaning brush if the corrosion is bad, but avoid putting any type of moisture into your hearing aid unless it’s absolutely necessary, then be sure to dry it completely before closing it again.

  1. Check the battery contacts.

The battery contacts are the small metal prongs that the battery touches when you close the battery door, and are what allow the battery to connect with the hearing aid to keep it working. If these are bent in any way or not properly lining up with the battery for some reason, this could be the cause of the distorted sound.

If you feel comfortable adjusting these yourself and are sure you know how they’re supposed to go, then go ahead and do so. Otherwise, you’ll have to take them in to have them fixed at your hearing center. Even if you think this may be the problem, you can continue through this troubleshooting guide in case it actually is another problem that you’re facing.

Troubleshoot Hearing Aid

  1. Check the memory or program.

If your hearing aid is one that uses various pre-set programs and memories so that you can easily switch between them to hear best in any situation, this could be the problem with the distorted sound. Sometimes, if the hearing aid is set on telecoil, this will cause sound distortion within the hearing aid, and simply switching it back to the proper setting for the environment you’re in.

  1. Check hearing aid for damage.

Carefully inspect your entire hearing aid for even the tiniest cracks, blockages, or signs of moisture as these can all be signs of internal damage that’s causing distorted sound. If you don’t see anything but know that your hearing aid has been dropped on a hard surface recently or that it got wet, then these could also be signs that there is some internal damage. Unfortunately, if there is internal damage causing sound distortion, there’s nothing more you can do except get to your hearing center.

  1. Ask about compatibility.

Sometimes, a hearing aid simply isn’t compatible with your ear or type of hearing loss. Although hearing center experts take steps to ensure that each person gets the right hearing aid for them the first time, this doesn’t always happen. If your hearing aid seems to be in good working order but you feel as though the distorted sound is still a problem, then ask about whether or not this might be the right hearing aid for you.
