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 a lot of different things that can harm the delicate that makes a hearing aid work the way it does, but few have the impact of water. Hearing aids seem to self-destruct under extreme moisture conditions. Even if you already know that and take care to protect your investment from the shower, pool, or a good face washing, chances are you are missing the most common reason for water damage in hearing aids: humidity.

Invisible moisture has the greatest chance of causing irreparable damage. It’s time to understand more about why humidity is a damaging thing for hearing aids.

Understanding Humidity

Despite the fact that the word humidity is very common, what does it actually mean? PBS defines humidity as water molecules in the air. When presented as a percentage, for example, the relative humidity is 40 percent today, it refers to the amount of water vapor in the air compared to what air could hold. The higher the percentage, the wetter everything feels.

Human beings are very sensitive to humidity because sweat is the most efficient way to cool the body. When you sweat it evaporates into the air, but that doesn’t happen as quickly when the humidity level is very high. Moisture and electronics don’t mix well and that includes hearing aids.

Typically Electronic Devices Have a Hard Time Coping With Humidity

Too high or, too low, humidity can impact your hearing aids. When water vapor percentages are high condensation can accumulate on the delicate mechanisms that make electronic devices function, and low humidity can result in brittle core materials.

Hearing aids rely heavily on internal electronics to function. A sophisticated signal processing chip manages noise levels in a modern hearing aid. It’s what is behind elegant functions like:

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

High humidity causes moisture to accumulate in the hearing aids destroying that chip. It can corrode elements inside the casing and ruin batteries also. It’s the equivalent of throwing your hearing aid in a bathtub of water.

How to Manage Humidity

Water resistant models are currently available. This feature will give you some protection against humidity and bad weather, but you still can’t swim with them in.

When it’s very humid try to decrease 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 the home will also be protected. Dust mites, mildew, and mold thrive in moist environments so a dehumidifier will improve the quality of breathing as well. 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. Silica gel crystals in a drying kit are used to protect 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. In a pinch, you could use a bag of uncooked rice to remove moisture.

Don’t forget to leave the battery door open when you store your device. When you expose the battery and inner elements to air by leaving the door open, condensation can evaporate by itself. Do this all year round, not just in the summer months.

Always store your hearing aids in a cool, dry place. Avoid putting them in the glove compartment, in a hot room or on a table in the sun.

Thinking Past Humidity

Damage can be caused by other types of wetness. 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.
  • Leave your hearing aids in a safe place before you go swimming.
  • Wear a sweatband when exercising. 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.
