How to wear a hearing aid? When using a hearing aid for the first time, you may feel that the sound is not realistic and clear enough. Because you have become accustomed to your original hearing condition, when using a hearing aid, you may hear unfamiliar sounds, so you may not be able to adapt for a while. The main method to solve the problem is to carry out necessary adaptability training. The initial wearing time should not be too long, the volume should not be too high, and gradually adapt.
How to conduct adaptability training? The adaptability training of hearing aids is not complicated, and the overall principle is to adhere to wearing and step by step adaptation:
(1) Improve daily usage time, preferably from short to long:
(2) From the perspective of volume adjustment, it is advisable to turn it down first and then up
(3) From the perspective of social environment, it is advisable to first be quiet before being messy, and then be simple before being complex
Only in this gradual manner can you quickly overcome the adaptation period and fully utilize the function of hearing aids.
Why does wearing a hearing aid cause howling?
If the contact area between the earplugs and the ear canal is not tightly sealed, the amplified sound will leak out from the gap and return to the microphone for further amplification, resulting in howling. such
The phenomenon is similar to the common howling sound that occurs when the microphone is close to the audio system.
(1) The proximity of a hand or an object to a hearing aid is caused by some sound being reflected on the palm or object and then transmitted back to the microphone for further amplification.
(2) The hearing aid is not fully inserted into the ear canal or not tightly sealed with the ear canal wall, resulting in amplified sound leakage and transmission back to the surface of the wind.
(3) There is a large amount of earwax in the ear, causing ear wax embolism. The amplified sound is reflected onto the earwax and transmitted back to the microphone, which will also generate feedback.
How to avoid howling?
(1) First, adjust the volume adjustment knob of the hearing aid to the "1" position, then insert the earplugs into the ear and try to tighten them as tightly as possible, and then adjust the volume to a clear position.
(2) If the earplugs cannot be tightened, please try using another more suitable earplug to tighten the ears and avoid air leakage.
