Are there waterproof hearing aids?
Hearing aids have to have some sort of opening for the microphone so that sound waves can get inside. Once inside, the computer chip in the hearing aid processes the signal (adjusting for noise, different frequencies and so on) and delivers the modified sounds to your eardrum.
Because there must be an opening for sound waves to get in to the aid there are no hearing aids that are completely waterproof (meaning you can’t store them in a bowl of water!). There are some new hearing aids that are surprisingly water-resistant.
What’s the problem with water and moisture?
Hearing aids are small electronic devices. They have one or more microphones, a receiver (or “speaker”), a computer chip, a battery for power, plus delicate wiring and other components. Electrical devices and water don’t mix. In fact, moisture, whether from water, sweat or humidity is one of the leading reasons hearing aids need to be repaired. In Texas this is an especially big problem.
What about these new Water Resistant hearing aids? How are they different?
Some new hearing aids are nano-coated to make them very water resistant. This coating is extremely thin – less than one thousandth the thickness of a human hair. The company doing this nano-coating is P2i www.p2ilabs.com. (Note: watch their video to see how this coating keeps water out!)
A few hearing aid manufacturers including ReSound and Starkey are now using this nano-coating technology on some of their hearing aid models. This coating makes them very resistant to moisture, which should greatly reduce the need for repairs. Nano-coating can only be applied during the manufacturing processing and is only available for BTE and RIC models.
