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 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, chances are you are missing the most common cause of water damage in hearing aids: humidity.

Permanent damage is done by moisture that you can’t see. It’s time to understand more about why humidity is a bad thing for hearing aids.

Let’s Talk About Humidity

Even though the word humidity is very common, what does it really mean? PBS defines humidity as water molecules in the air. When displayed 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. When you can feel wetness in the air, that means the relative humidity is high.

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 quickly 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.

Understand Humidities Effect on Hearing Aids

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

Internal electronics are the reason your hearing aids work. An advanced audio processing chip manages noise levels in a modern hearing aid. Because of this, you get amazing features like:

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

High humidity causes moisture to accumulate inside the hearing aids destroying that chip. 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. This feature will give you some protection against humidity and wet weather, but you still can’t swim with them in.

When it’s very humid try to lessen indoor water vapor by utilizing a dehumidifier. It’s an investment that will benefit you and your family in numerous ways and protect other electronic devices like that expensive TV you got for Christmas. 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. You will need to take other steps at the same time.

Look for the dehumidifier made for hearing aids. There is one out there for every budget. Drying kits rely on silica gel crystals to protect the 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.

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. Don’t just do this in the summer, do it all year round.

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:

  • 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.
  • When exercising wear a sweatband. It’s a good practice whether you wear your hearing aids when you workout or not. Later that sweat will cause problems.
  • Check surfaces before you put your hearing aid down. 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.
