The matching hearing aids are different, their wearing effect may be different.For example, an optional high-powerHearing aid, An optional with frequency shift functionHearing aid.The direct compensation of high-power hearing aids has less sound loss, but there may also be serious low-frequency ear plugging effects, low-frequency low-frequency sound can not be heard, and high-frequency compensation is not enough to still be inaudible. Hearing aids with frequency shift function pass Frequency shift technology can well compensate for the high frequency partHearing loss, Especially for hearing impaired people with cochlear dead zone at high frequency.At this time, their wearing effect and feeling may be very different! But it is worth exploring that some people feel that the sound distortion after frequency shifting is serious and unacceptable, so there are two people with similar situations Choose the same hearing aid, but the result is far different.
In fact, hearing aids, like our glasses, are just an auxiliary tool. The earliest hearing aids became loudspeakers, simply amplifying the sound. Now most hearing aids are digital hearing aids.It can selectively amplify the sounds of different frequencies according to the hearing of each frequency and the needs of the patient, and can also achieve noise reduction. Of course, this is only the majority. There are still a small number of analog machines on the market, that is, loudspeakers.
