(included) ProductDescription : Possible problem when wearing the hearing device: How to solve the whistling? Adjust the volume to normal.The volume of the hearing device is turned on to the maximum because of the product test, it needs to be turned down at the beginning use. Selecting an appropriately-sized earplug to keep the ear canal sealed , can effectively prevent the whistling. How to relieve feeling dizzy when wearing the hearing device? The initial wearing of hearing aids has a process of adaptation. Now wearing in a quiet environment, the wearing time needs to adapt slowly, please refer to USER GUIDE. Why would hear the noise? Normal hearing is accustomed to external environmental noises such as computer fans, air conditioners, and road noises for a long time. However, after hearing loss, the sound cannot be heard for a long time and in a relatively quiet space. Once you wear the hearing aids will feel that the environment is noisy and unaccustomed, and need to adapt for a while. The noise is whistling, which is a positive feedback whistling sound generated by the sound from the hearing aid horn after being leaked and picked up by the microphone. The solution is to cut off the feedback path, reduce the sound leakage, choose an appropriately-sized earplug and wear it seal. Why no sounds can be heard from the hearing device? Check whether the volume is adjusted to suit your hearing situation. Check whether the hearing device has power. Check whether the ear canal is not cleaned and the cerumen is blocking the sound outlet of the hearing aid.
