Are There Hearing Aids That Are Waterproof? Is It OK To Put On Hearing Aids In The Swimming Pool?

Hearing aids are prone to all forms of moisture and their is no way to avoid it completely. The best you can do to care for your investment and your instruments is to keep an acceptable level of dryness and that can be done in a number of ways.
People frequently asked if there is such a thing as a water-resistant hearing aid. The answer is “not any that have been effective.” Part of the reason why hearing aids continue to have moisture issues is attributable to the battery. The batteries in hearing aids are air initiated… that means that they ought to be exposed to the air to work. If the hearing aids were completely sealed from air, the batteries would not work (therefore, they cannot be easily sealed from water for the same explanation). Also, if the aids are sealed and moisture gets in the aid it won’t be able to escape back out. If moisture becomes trapped inside the hearing aid you then have battery decay issues and possibly moisture linked failure of the amplifier, and/or processor (or other delicate parts of the hearing aid). So, some escape of air (and water) is necessary for a hearing aid to operate. Perhaps sooner or later with sciences like Nanotechnology we will finally be able to generate a membrane barrier that will not allow moisture in but will allow moisture to flow and air in for the battery. Perhaps with improvements to the batteries (for instance the new rechargables that are coming out) we will no longer require zinc-air battery cells for power. Some makers are starting to play around with Nanotechnology and it is an intriguing science. Maybe someday consumers will see many of their troubles bit by bit addressed as appropriate solutions are put on the market.
As for dampness prevention solutions… Firstly, you cannot go for a dip with your hearing aids in, but if you are going to put on your in-the-ear (ITE) aids in or around the swimming pool or other potentially harmful places, at the very least find a head wrap called EarBandit. This will also hold the aids from plunging in the water. For those of you that put on behind-the-ear (BTE) hearing aids, you can also use the sweatband or EarGear products. These are not water-resistant options and you still have to keep away from getting the aids damp… but they will provide splashguard. Therefore, you can unwind a little and have some fun. When you are through for the day at the pool… let your hearing aids dry up for 8 hours prior to wearing them yet again. Unfasten the battery access and put in a dry, safe place. Never utilize hair dryers, heat lamps, hot air guns, microwaves or ovens to dry up the hearing aids.
