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 ruin 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, more than likely you are missing the most common cause of water damage in hearing aids: humidity.

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 does it mean? PBS defines 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. 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 very 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 influence your hearing aids. When water vapor percentages are high condensation can collect on the intricate elements that make electronics function, and low humidity can result in brittle core materials.

Hearing aids depend heavily on internal electronics to work. Modern digital hearing aids use a state-of-the-art signal processing chip to control noise. 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. It can corrode elements inside the casing and ruin batteries also. You might as well drop your hearing aid in a pool full of water, and the effect is the same.

How to Control Humidity

If you are shopping for hearing aids, look for products that are water-resistant. This feature will give you some protection from 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 just your hearing aid that will benefit, there are health benefits, and other electronic devices in the home 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. 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. 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.

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. 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

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.
  • Find a safe place to store your hearing aids if headed for the pool or beach.
  • 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.
  • 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.
