1. Speaker blockage: the bell mouth of the customized hearing aid is toward the inner part of the ear canal, and the ear canal will secrete staring wax (commonly known as earwax), which is easy to block the sound hole. A small amount of blockage of the hearing aid will reduce the sound. When the blockage is serious, the hearing aid will have no sound. If the hearing aid is blocked for a long time, the speaker is easy to be blocked
2. Microphone blockage: the oil secreted in the ear canal is very easy to enter the microphone of the hearing aid. Many hearing aids go to the fitting center and find that the speakers and microphones are full of oil, which is a great damage to the hearing aid. Not only the microphone is damaged, but also the hearing aid chip is corroded.
Therefore, the service life of hearing aids is as long as 5-8 years. Be sure to clean the speaker and microphone of the hearing aid regularly to prolong the service life of the hearing aid.
