Why do some users wear ear canal hearing aids for a long time? The ear canal is often wet?

The external auditory canal of the person is an open tube with one end closed, but the ear canal is blocked by the ear canal hearing aid, and the air mobility is greatly weakened. Thus, the sealing time is easy to form a "wet box", and the external ear canal skin moisture of some users. The amount of evaporation is large, and the humidity is greater after the hearing aid is used to close the external auditory canal, so the ear canal is particularly prone to moisture. Some users who have a history of chronic otitis media are prone to relapse. The moisture in the ear canal is particularly easy to contact and corrode the receiver and chip of the ear canal hearing aid, so maintenance is often required without paying attention to maintenance. A better improvement method is: it is recommended to make a vent hole for the hearing aid casing, or to loosen the outer casing to improve the air mobility; when the user wears the hearing aid, the pressure should not be too tight; sometimes the hearing aid is used to open the external auditory canal; if the hearing loss is better than Light users can replace hearing aids with open ear options; electronic dryers are often used, and dry hearing aids are regularly maintained at the hearing center.
