Dog jumping into water to demonstrate how hearing aids can get wet easily when you're having fun this summer because moisture damages hearing aids.

There are many factors which can affect the circuitry of your hearing aids. Hearing aids seem to self-destruct under severe moisture conditions. Even if you already know that and take care to protect your investment from the shower, pool, or a good face washing, more than likely you are missing the most common reason for water damage in hearing aids: humidity.

Moisture that you can’t see has the greatest chance of causing permanent damage. It’s essential to educate yourself about why humidity damages hearing aids.

Let’s Talk About Humidity

Even though the word humidity is very common, what does it really mean? PBS describes humidity as water molecules in the air. The relative humidity refers to the ratio of water molecules in the air compared to how many the air can actually hold. The greater the percentage, the wetter everything feels.

Humans cool their body by sweating so that makes us very sensitive to humidity. When humidity levels are high our sweat won’t evaporate as fast. Electronics are also susceptible to humidity and that is why it has such a detrimental effect on hearing aids.

Typically Electronic Devices Have a Hard Time Coping With Humid Weather

Too high or, too low, humidity can influence your hearing aids. When it’s too moist, the delicate electronics will accumulate condensation. When it’s too dry things become more brittle.

Hearing aids rely heavily on internal electronics to work. Modern digital hearing aids use a sophisticated signal processing chip to control noise. It’s what is behind elegant features like:

  • Noise reduction
  • Anti-feedback
  • Targeted listening programs
  • Digital sound streaming

High humidity causes moisture to collect in the hearing aids damaging that chip. It can corrode elements inside the casing and destroy batteries as well. It’s the same as dropping your hearing aid in a bathtub of water.

How to Manage Humidity

If you are shopping for hearing aids, try to find products that are water-resistant. This feature will give you some protection against humidity and wet weather, but you still can’t go swimming with them in.

When it’s very humid try to reduce indoor water vapor by utilizing a dehumidifier. It’s not only your hearing aid that will benefit, there are health benefits, and other electronic devices in your house will also be protected. Dehumidifiers reduce the risk of mold, mildew and dust mites, so everyone breathes a little better, too. Although a house or room dehumidifier will help protect your hearing aids, it’s not enough. There are a few other things you can and should do.

Consider buying a dehumidifier designed especially for hearing aids. They come at all costs levels. Drying kits rely on silica gel crystals to protect the electronics. Moisture is eliminated by putting the hearing aids into the dehumidifier for a couple of hours. There are also storage containers that dry hearing aids out each night as you sleep. If it is very humid and you have no other way, uncooked rice can reduce moisture.

Don’t forget to leave the battery door open when you store your device. By pulling that door open before you put the hearing aid down, you expose the batteries and other elements to the air, allowing any condensation built up to evaporate naturally. Do this all year round, not just in the summer months.

Always store your hearing aids in a cool, dry place. On the table in the sun, in the glove compartment, or in a hot room are examples of where not to store your hearing aids.

Thinking Beyond Humidity

Air vapor is not the only moisture that can damage hearing aids. Don’t forget to think about other types of wetness like:

  • Make sure all lotion or sunscreen is fully absorbed before touching your hearing aids or putting them in your ears.
  • Find a safe place to store your hearing aids if headed for the pool or beach.
  • When exercising wear a sweatband. If you are wearing your hearing aid then it’s a good idea in general. Later that sweat will cause problems.
  • Try not to put your hearing aid down on wet surfaces. A glass or coffee cup can leave moisture behind.

Your hearing aids are a valuable asset, so treat them that way. Consider how moisture and humidity can impact them and take steps to prevent water damage. If your hearing aid already has water damage make an appointment for service with a hearing aid specialist.
