Hearing Aids for Seniors Rechargeable with Noise Cancelling, COOCEER Adults Hearing Amplifiers with Volume Control, 40-Hours of Use on One Charge, Cleaning Kit, Domes, Case and Charge Cable (Single) Musical Instruments Blue ThunderBrand: COOCEER Part Number: KV601 Details: Q&A: Why does the hearing aid have loud screeching sound ? How to solve? Because the contact part of the earplug and the ear canal is not completely closed, the sound amplified by the hearing aid leaks from the gap and is amplified again by the microphone, so there will be a howling sound. Solution: 1. Turn the volume to minimum first, then turn on the switch after wearing it well. 2. Choose suitable earplugs
