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 damage the delicate technology that makes a hearing aid work the way it does, but not many have the impact of water. In fact, you could call moisture kryptonite for hearing aids. 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 highest chance of causing permanent damage. It’s important to educate yourself about why humidity damages hearing aids.

Let’s Talk About 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.

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.

Why Hearing Aids Have a Problem with Humidity

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

Hearing aids rely heavily on internal electronics to function. A sophisticated signal processing chip controls noise levels in a modern hearing aid. Because of this, you get awesome features 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 same as dropping your hearing aid in a sink of water.

Managing Humidity

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

When it’s very humid try to lessen indoor water vapor by utilizing a dehumidifier. It’s not just 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. However, protecting your hearing aid more completely will require additional thinking. There are a few other things you can and should do.

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. Moisture is eliminated by putting the hearing aids into the dehumidifier for a couple of hours. 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. 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:

  • 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. 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.

Treat your hearing like the valuable asset that it is. Keep in mind how moisture can damage your hearing aids and make sure to prevent water from getting in them. If your hearing aid already has water damage make an appointment for service with a hearing aid specialist.
