Common Hearing Aid Problems & How To Fix Them

Once hearing aids have become seamlessly incorporated into your life, they may not be the first thing on your mind. That’s their purpose, of course: to amplify sounds and provide you with accessibility to the world around you.

As with other electronic devices, hearing aids may malfunction from time to time. We advise you to not take apart your hearing aids or attempt to make major repairs on your own. Here we provide you with a few common hearing aid problems and how to troubleshoot them.

Familiarize Yourself With Your Hearing Aid’s Parts

First things first: get to know the parts of your hearing aids. Though hearing aids come in many different sizes, shapes, and styles, they share the same major components:

  • Microphone: picks up sound.
  • Amplifier: makes sound louder.
  • Receiver: sends amplified sound into ear
  • Battery: provides energy supply.

Receiver-in-canal or behind-the-ear hearing aids have plastic or wire tubing that connect a custom-molded part to the plastic housing work over the ear. In-the-ear hearing aid parts are all housed in one plastic casing, inserted into your ear.

No Sound Or Inconsistent Sound

Blockage: Remove your hearing aids and check to see if there is debris or earwax blocking any of the components If you see build-up, carefully clean your hearing aids according to instructions we have provided you.

Battery issues: Are the batteries out of juice? Check to make sure your batteries are full. If you use rechargeable hearing aids, make sure that your recharging station is plugged in and functioning properly. For traditional hearing aid batteries, check to make sure that they are securely inserted and that the battery door is closed properly. Sometimes, the battery may just be dislodged.

Check the volume: Is there a chance you accidentally turned down the volume? Newer digital hearing aids allow wearers to control their listening experience through downloadable smartphone apps. Check to make sure the volume levels are set properly – and are not on mute!


Whistling usually occurs due to feedback; sometimes, your hearing aid microphone might pick up the amplified sound and create a loop. The high-pitched whistling sound may cause discomfort for you and those around you. The following things could cause whistling:

Volume turned up too high: If you’ve got the volume on your hearing aid turned up to the highest level, this could cause feedback. Your hearing aid should not be turned up to the highest volume. If you find that your hearing aid volume is constantly turned up high, it may be time to visit your hearing specialist for a more powerful device.

Poor fit: A loose-fitting hearing aid may be the cause of this whistling sound. When the mold of the hearing aid does not fit properly inside your ear, and the vents are not properly secured, this may lead to the whistle. If you’ve noticed a loose fit, visit us to get a new ear mold made.

Problems with the hearing aid: There may be a defect with your hearing aids. Check your warranty and visit us at Hearing Spa for professional repairs. If you are looking for a new pair of hearing aids, check to see if they offer feedback cancellation features.  

Hearing Aid Maintenance Tips

Avoid moisture

Hearing aids are comprised of sensitive electronic components. Although they are often housed in plastic, exposure to moisture has the potential to damage them. Rather than storing them in your washroom, where moisture may collect after a shower, keep them in a cool, dry space.

Here in Florida, where the weather can be very humid, invest in a dehumidifying unit for your hearing aids. Often times, these units also double as battery chargers. Remember to remove your hearing aids before swimming or showering, as well as washing your face or shaving. At the same time, remember to remove them before using a hair dryer, as the heat may also cause damage.

Clean your hearing aids

Your hearing aids may pick up dust, lint, or earwax during daily wear. This debris may cause damage to your hearing aid by clogging up certain components. Carefully clean your hearing aids with a soft, lint-free cloth, soft toothbrush, or cotton swab. Be sure to follow instructions provided that we’ve provided for your specific hearing aid model, and do not attempt to dissemble or clean the intricate components.

Store your hearing aids in a safe place

With many small components, hearing aids may prove dangerous for pets and children. If they are in a precarious area, they may get knocked over and damaged.

Battery levels

Test your battery levels daily to assure optimal performance. When not in use, we recommend removing the batteries from the hearing aid. For rechargeable hearing aids, follow the instructions for your particular hearing aid model.

Schedule a regular professional maintenance and cleaning. If you need a hearing aid repair, let us know.
