At present, hearing aids on the market all have whistling. If you wear and use them correctly, the whistling will be greatly reduced. There will be a small echo hole on the hearing aid. Do not block it, and do not place the hearing aid in a small closed space.
Hearing aids can amplify sound to help you hear more clear, but cannot treat deafness. If you have special requirements for hearing, you need to go to the hospital for testing and customize hearing aids that suit you.
