Why can waterproof hearing aids be used? What kind of water?

At present, the highest dust-proof and waterproof level of hearing aids is IP68 (meaning dust-proof up to 6, water-proof up to 8). The coefficient of water-proof up to 8 means that hearing aids can still operate normally after being placed for 60 minutes under the water for 1 meter under the test of a third-party testing agency. Apple 7 series phones are also waterproof.

Why can hearing aids be waterproof?

The unique technology of the shell and the inner layer keeps the water firmly isolated. See the rubber ring in the door of the battery compartment in the picture? This is one of the waterproof processes. Don’t look down on this. To be small, light and waterproof, you need to be highly skilled.

Waterproof ≠ anti perspiration, because perspiration will become perspiration steam

Sweating is a form of evaporation of the human body, just like the water evaporated by photosynthesis of plants. When we’re sweating, we’re actually steaming hot air. That’s why we can see white air when we sweat a lot in winter.

Although the liquid sweat beads can not enter the hearing aid directly, the “sweat steam” can invade the interior in the form of vapor body, and form the condensate with salt, which eventually becomes the main culprit of corrosion.

However, if sweat is rolled off or wiped off, it will not evaporate, so the wearer of hearing aid should timely use paper towel or dry cloth to dry the hearing aid and the sweat around the ears in daily life.

Waterproof ≠ moisture proof

Even IP68 grade waterproof hearing aids are afraid of moisture. In the wet season or after the rain, users should immediately use paper towels or dry cloth to absorb moisture, which can prevent the generation of moisture. Because humidity, like air, penetrates everywhere. Once inside the hearing aid, the electronic components will be damped.

Many users have such a misunderstanding: every day when they go home, they can put the hearing aid into the drying box to dry, but in fact, after more than ten hours a day, although the water has not penetrated directly, the moisture has already sneaked in. So please keep in mind: once there is perspiration, rain or wet environment, immediately take off the hearing aid and dry it with a paper towel, and then go home to dry it.

Take good care of your hearing aid, it will bring you more comfortable listening. So if my hearing aid doesn’t reach the IP68 dust-proof and waterproof level, or I want to give more protection to the hearing aid? You can also add a pair of protective covers to the hearing aid to absorb sweat, moisture and dust.
