4. Why does the hearing aid beep when it is turned on?

The main reason for hearing aids in general is that the eardrum has a sound leak at the contact area with the external auditory canal. The amplified sound through the hearing aid is covered by the ear canal , and then amplified by the microphone, and then the is generated, so the opening opportunity is normal.

* Why is there a noise in the hearing aid?

Because the hearing aid belongs to the electronic product, it has a current sound. It is generally considered to be a noise, not to say that there is no so-called noise at all. Even the best machines have current sounds, as long as they buy it back to the elderly. Or when the parents use it, as long as the operation is correct, this so-called murmur can be slowly adapted according to time.

1. Check if the size of the earplug (silica ) is suitable and it is tight. (Because the hearing aid is not in contact with the air, if the earplug is not tight, the wind will have a large current.)

2. At the beginning, do not turn the volume down a bit. Generally, don't open it very loudly at first. (It is recommended to adjust to a file or a second file when you first start hiding. If you don';t want to wear it, then you can wear it slowly. increase.

3. Sometimes the elderly or parents will get used to the previous hearing, so when I first started using the hearing aid, I heard some unfamiliar sounds, and I felt that it was noise and I could not hear clearly. In fact, this is to enlarge the sound that we can't usually hear. Generally, it will adapt to some time. (Generally, I';d like to wear a hearing aid for eight hours a day, then I';ll take two to three weeks and I';ll get used to it.)
