First, why is there a noise in the hearing aid?
Hearing aids are electronic products, so they have a current sound. They generally think that it is a noise. It is not that there is no so-called noise at all. Even the best machines have current sounds, as long as the user operates. Correctly, this so-called murmur can be slowly adapted to the time.
1. Check if the size of the earplug is suitable for the user and whether it is tight.
Because the hearing aid can't be in contact with the air, if the earplug is not tight and the air leaks, there will be a lot of current.
2, as soon as possible to turn the volume down a bit, generally do not open to the maximum sound at first.
It is recommended to adjust to the first or second gear when you first start wearing it. Wear it first. If you can't hear it, adjust the volume slowly.
3. Sometimes the elderly or mom and dad are accustomed to the previous hearing, so when I first started using the hearing aid to hear some unfamiliar sounds, I felt that kind of noise, I couldn’t hear clearly, the hearing aid was like a small horn, and we usually The sound that can't be heard is magnified, and it usually takes some time to adapt.
Second, why does the hearing aid scream when it is turned on?
The main reason for the general hearing of the hearing aid is that the eardrum and the external auditory canal have sound leakage, and the contact between the earplug and the ear canal is not tight. The sound amplified by the hearing aid leaks through the gap of the ear canal, is picked up by the microphone and then amplified, and a howling is generated, so the opportunity to open is normal.
Correct wearing method: When using, choose the earplug of the appropriate size. If the earplug is not suitable, there will be a howling when there is a gap. In addition, remember to turn off the switch when the speaker is worn, and the sound is adjusted to the minimum. After the boot is turned on, the sound is gradually increased until the sound is turned up. Can listen to it, to avoid excessive sound to stimulate the user's ears.
