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 that makes a hearing aid function the way it does, but few have the impact of water. In fact, you could call moisture kryptonite for hearing aids. Taking that into consideration, humidity is a big problem.

Moisture that you can’t see has the highest chance of causing irreparable damage. It’s time to learn more about why humidity is a bad thing for hearing aids.

Understanding Humidity

Humidity is a word that gets talked about a lot, especially during the summer months, but what is humidity? 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.

People 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 high. Electronics are also susceptible to humidity and that is why it has such a detrimental effect on hearing aids.

Why Electronics Have a Problem with Humid Weather

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 depend heavily on internal electronics to work. Modern digital hearing aids use a sophisticated signal processing chip to control noise. It’s what is behind elegant features like:

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

High humidity causes moisture to collect inside the hearing aids damaging that chip. It can corrode elements inside the casing and destroy batteries also. It’s the equivalent of throwing your hearing aid in a pool of water.

How to Control Humidity

If you are looking at hearing aids, look for products that are water-resistant. Having this feature doesn’t mean you can go swimming with your hearing aids in your ear, but it does give some protection against humidity and other weather-related concerns such as getting caught in an unforeseen rainstorm or even sweat when you work out.

When it’s very humid try to lessen indoor water vapor by using a dehumidifier. It’s an investment that will help you and your family in numerous ways and protect other electronic devices like that expensive TV you got for Christmas. Dehumidifiers reduce the risk of mold, mildew and dust mites, so everyone breathes a little better, too. 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.

Look for the dehumidifier made for hearing aids. There is one out there for every budget. 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.

Don’t forget to leave the battery door open when you store your device. 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. Do this all year round, not just in the summer months.

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