【Why is there a strange sound (howling/noise)?】
In order to make a smaller sized hearing aid, the internal amplifier and the microphone must be close to each other. The sound is continuously received and expanded, so there is a possibility of producing a howling sound when the power is turned on.At present, it is not likely that small hearing aids and high-powered hearing aids on the market can avoid the howling.
【How to avoid whistling】：
Operate so that the hearing aid is completely closed to the ear canal, such as larger earplugs, adjusting the position and volume, etc.
