4. WHISTLER

It's also called acoustic feedback, which is a normal phenomenon occurring in working of hearing aid. It is more likely to occur to the one with larger power and higher power. In the event of it, the following methods shall be used for improvement:

1. Reduce the volume
2. Fit the earplug and air canal closely or replace with larger earplug, ensuring the sound not leaked or leaked as little as possible
3. Turning up gradually, and then leave the hand away from the ear, avoiding acoustic reflection. At this moment, the whistler will be controlled.
