Does Moist Weather Harm Your Hearing Aids?

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 electrical circuitry of your hearing aids. In fact, you could call moisture kryptonite for hearing aids. Taking that into consideration, humidity is a huge problem.

Irreversible damage is done by invisible moisture. It’s essential to educate yourself about why humidity harms hearing aids.

Understanding Humidity

Humidity is a word that gets bounced around a lot, especially during the summer months, but what is humidity? 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 larger the percentage, the wetter everything feels.

Humans cool their body by sweating so that makes us very sensitive to humidity. When you sweat it evaporates into the air, but that doesn’t happen as fast when the humidity level is high. Electronics are also susceptible to humidity and that is why it has such a detrimental effect on hearing aids.

Why Hearing Aids Have a Problem with Humidity

Too high or, too low, humidity can influence your hearing aids. When water vapor percentages are high condensation can collect on the intricate mechanisms that make electronics function, and low humidity can cause brittle core materials.

Hearing aids depend heavily on internal electronics to function. Newer digital hearing aids use a state-of-the-art audio processing chip to manage noise. It’s what is behind elegant features like:

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

Moisture can accumulate in the hearing aid when humidity is high and harm that component. Batteries get destroyed and you get corrosion of elements inside of the case. You might as well throw your hearing aid in a pool full of water, and the effect is the same.

Keeping Humidity Under Control

If you are investing in hearing aids, try to look for products that are water-resistant. Having this feature doesn’t mean you can swim with your hearing aids in place, but it does offer some protection against humidity and other weather-related concerns like getting caught in an unexpected rainstorm or even sweat when you work out.

If you live in a humid area, consider using a room or house dehumidifier to cut down on water vapor indoors. It’s not just your hearing aid that will benefit, there are health benefits, and other electronics in your house will also be protected. Dust mites, mildew, and mold thrive in moist environments so a dehumidifier will improve the quality of breathing as well. However, protecting your hearing aid more completely will require additional thinking. 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. You put the device in the dehumidifier for a couple of hours to eliminate moisture. Drying your hearing aids as you sleep at night can be done using specially designed storage containers. In a pinch, you could use a bag of uncooked rice to remove moisture.

Get in the habit of opening the battery compartment every time you store your hearing aids. 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. Don’t just do this in the summer, do it all year round.

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. Take precautions to protect them from other kinds of wet such as:

  • Don’t touch your hearing aids with hands that are still moist from lotion.
  • Leave your hearing aids in a safe place before you go swimming.
  • Wear a sweatband when exercising. It’s a good practice whether you wear your hearing aids when you workout or not. Later that sweat will cause problems.
  • Try not to put your hearing aid down on wet surfaces. You don’t want to place it in a wet spot left by a glass or coffee cup.

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.
