Tips for buyers:
The cause of howling/noise:The internal amplifier and microphone are close to each other of the hearing aid, and the sound is continuously received and expanded, so it has a certain possibility of generating howling after power on. At present, small hearing aids and high-power hearing aids on the market can hardly avoid howling, and only full digital hearing aids can avoid howling.
Ways to avoid howling/noise:
1. When the power is high (the amplified sound is large), howling is more likely to occur. Therefore, gradually increasing the volume from low can effectively avoid howling.
2. When the ear canal is completely sealed, there will be no howling sound. Therefore, after cleaning your ear canal, please use hearing aids and test the earplugs from large to small to find the most suitable earplugs. Suitable airtight earplugs are recommended.
3. After the hearing aid enters the ear canal, it is recommended to press the hearing aid with your fingers and hold it for 1-2 seconds and adjust the earplugs to the ear canal.
