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 function 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, chances are you are missing the most common reason for water damage in hearing aids: humidity.

Invisible moisture has the greatest chance of causing irreparable damage. It’s time to understand more about why humidity is a negative thing for hearing aids.

What is Humidity?

Even though the word humidity is very common, what does it really mean? 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. 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 fast when the humidity level is high. Moisture and electronics don’t mix well and that includes hearing aids.

Understand Humidities Effect on Hearing Aids

Oddly enough, electronic devices are not only sensitive to high humidity but low levels as well. When water vapor percentages are high condensation can collect on the delicate elements that make electronics function, and low humidity can result in brittle core materials.

Internal electronics are the reason your hearing aids work. A sophisticated signal processing chip controls noise levels in a newer 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 collect in the hearing aids damaging that chip. Batteries get ruined and you get corrosion of elements inside of the case. You might as well drop your hearing aid in a tub full of water, and the effect is the same.

Keeping Humidity Under Control

Water resistant models are currently available. Having this feature doesn’t mean you can swim with your hearing aids in place, but it does give some protection from humidity and other weather-related concerns such as getting caught in an unforeseen rainstorm or even sweat when you exercise.

If you live in a humid area, think about using a room or house dehumidifier to reduce water vapor indoors. 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. You will need to take other steps at the same time.

Consider buying a dehumidifier designed especially for hearing aids. There is one out there for every budget. Silica gel crystals in a drying kit are used to protect electronics. Moisture is eliminated by putting the hearing aids into the dehumidifier for a couple of hours. 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. Don’t just do this in the summer, do it all year round.

A cool dry place is the ideal for storage. Avoid putting them in the glove compartment, in a hot room or on a table in the sun.

Other Moisture Considerations

Air vapor is not the only moisture that can damage hearing aids. 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. If you are wearing your hearing aid then it’s a good idea in general. Later that sweat will cause problems.
  • Check surfaces before you put your hearing aid down. A glass or coffee cup can leave moisture behind.

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.
