Problems often encountered when wearing hearing aids

1. How to wear hearing aids?  

  When using hearing aids for the first time, you may feel that the sound is not real and clear enough. Because you are used to the original hearing condition, when hearing aid is used, I heard some unfamiliar voices., therefore, it cannot be adapted for a while. The main method to solve the problem is to carry out necessary adaptive training., don't wear it too long at the beginning, the volume should not be too large., slowly adapt.

2. How to conduct adaptive training? 

  Adaptive Training of hearing aids is not complicated., the general principle is to insist on wearing and adapting step by step:

   (1) from the daily wearing time, from short to long;

   (2) judging from the volume adjustment, small first and Big later;

   (3) from the perspective of communication environment, it should be quiet first and then Cao Miscellaneous, simple first and complicated.

So step by step, only in this way can you get through the adaptation period as soon as possible, to maximize the role of hearing aids.

  3. Why does hearing aid produce howling?

Earplugs and meatus acusticus contact parts are not tightly closed, the amplified sound leaked from the gap and returned to the microphone to be amplified again.. It will produce howling. This phenomenon is similar to our common microphone whistling when approaching the stereo.

(1) the hand or an object is close to the hearing aid, because part of the sound is reflected on the palm or object and sent back to the microphone for further amplification.

(2) the hearing aid is not completely inserted into the meatus acusticus or is not tightly sealed with the meatus acusticus Wall. The amplified sound is leaked and sent back to the microphone.

(3) there are a lot of earwax in the ear, and ear wax embolism occurs. The amplified sound is reflected to the earwax and transmitted to the microphone again, which will also generate feedback.

4. How to avoid howling?      

  (1) first adjust the hearing aid volume adjustment knob"1" position, then plug the earplugs into the ear and try to plug them tightly, and then adjust the volume to the clearest position.

 (2) if the earplugs cannot be tight, please try another more suitable earplugs, and plug the ears tightly., do not leak air.
