The Secret of Waterproof Hearing Aid

At present, the highest dustproof and waterproof level of waterproof hearing aid is IP68 (meaning dust is up to 6 and waterproof is up to 8).

Why is waterproof hearing aid waterproof?

The unique process of the outer shell and inner layer keeps the water firmly isolated.

Waterproof is not equal to sweatproof, because sweat will turn into steam

Sweating is a form of evaporation of the human body, just like the evaporation of water from photosynthesis in plants. When we are constantly sweating, in fact, the body is constantly braving the heat. This is why when we sweat a lot in winter, we can see that we have white steam.

Although the liquid sweat can't directly enter the hearing aid, the "sweat steam" can invade the inside in the form of vapor and form condensed water with salt, which eventually becomes the culprit of corrosion.

However, if the sweat is rolled off or wiped off, it will not be evaporated. Therefore, the hearing aid wearer should use a paper towel or a dry cloth to dry the hearing aid and the sweat around the ear in daily life.

Waterproof is not equal to moisture resistance

Even IP68-rated waterproof hearing aid is afraid of moisture. In the wet season or after the rain, the user should immediately use a paper towel or dry cloth to absorb moisture, which can prevent moisture. Because moisture is like air, it will seep into all places. Once invaded into the hearing aid, the electronic components are damp.

There are a lot of users who have this misunderstanding: after going home every day, putting the hearing aid into the dry box will make you feel better. But in fact, a dozen hours a day, although the water did not directly infiltrate, but the humidity has quietly sneaked into. Therefore, please remember: once you are sweating, raining or in a humid environment, immediately remove the hearing aid and use a paper towel to absorb the water vapor, then go home and dry.

Take good care of your waterproof hearing aid, which will give you a more comfortable listening experience.
