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 is no howling sound. Therefore, please use hearing aids after cleaning your ear canal, and test the earplugs from large to small to find the most suitable earplugs.
3. After the hearing aid enters the ear canal, it is recommended to push the hearing aid with your fingers and hold it for 1-2 seconds, and then release it to fully extend the earplug.

Frequently Asked Questions:
1. Why is there noise when wearing hearing aids?
Many users buy it for their family members. If the buyer's hearing is normal, they will try it on themselves. They will not hear clearly and are very noisy. They are generally considered to be noise. This is not a noise. Regular hearing aids do not have so-called noise. They are generally called noise, voice. All hearing aids are available. Our hearing aids are made in strict accordance with the national noise standards. The average hearing patient cannot hear this noise. Some hearing loss is not so severe and can hear a little noise. This can be adapted slowly.
A. Check whether the size of the earplugs (silicone) is appropriate and whether it is plugged tightly (hearing aids must not be in contact with the air. If the earplugs are not plugged tightly and air leakage will result in a loud current noise.)
B. At the beginning, try to reduce the volume as much as possible, and generally try not to turn it to the maximum at the beginning (when you first wear it, please set the sound to the first or second gear)
C. Sometimes family members are used to the previous hearing, so at the beginning, when using hearing aids, they will hear some unfamiliar sounds. They feel that this is noise, and I feel that I can hear clearly. In fact, this is the birth of a child that I can't hear. It's good to zoom in and adapt to a period of time. (At first, it is recommended to wear it for about 2-3 hours a day, and then slowly adapt after 2-3 weeks.)
2. Why does the hearing aid hear the squeaking sound as soon as it is turned on?
The main reason for the general whistling of hearing aids is the sound leakage at the contact part of the eardrum and the external auditory canal. The sound amplified by the hearing aid leaks through the gap in the ear canal, and is amplified by the microphone, and it will produce coughing. Therefore, it is normal to open the opportunity to call. It is recommended to select the appropriate earplugs when using it, and then the sound is turned down and then plugged into the ear. it is okay.
3. How to maintain and clean hearing aids?
The habit of cleaning hearing aids, use the provided brush to remove the earwax or other tiny particles that have accumulated around the ear canal of the hearing aid, the volume adjustment knob and the battery compartment, and then gently wipe the hearing aid with a soft cloth. Never use solvents and clean Liquid or oil cleaning hearing aids When the hearing aids are not in use, turn off the switch and open the battery door, which can extend the battery life. If the hearing aid is not turned off, it will emit a "squeaking" sound, which may attract the attention of children or pets and cause unnecessary damage.
