Precautions
1 Why is there a noise in hearing amplifiers?
Hearing Sound Amplifier are electronic products, and there will be a small current sound. People who use it for the first time will think it is a noise. As long as they are worn in the correct way, the noise can slowly adapt to the time.
2 Why does a hearing amplifiers turn on and cause a howling?
The reason for the howling of the hearing sound amplifier is that there is sound leakage at the contact part of the eardrum and the external auditory meatus. After the hearing amplifier is amplified, it leaks through the gap of the ear canal and is absorbed by the microphone and amplified. Therefore, howling after booting is normal. It is recommended to select the appropriate earplugs to close the ears, adjust the sound to the minimum, and then turn on to avoid howling
