Whether the hearing aid is worn well or not, these factors will affect the hearing aid

In the process of wearing hearing aids, patients usually feel that the sound quality of hearing aids is not good, there is always noise, but also accompanied by tinnitus, resulting in uncomfortable wearing hearing aids. Jinghao hearing aids remind you to choose a better and trustworthy brand hearing aids to ensure the quality, so what are the common reasons for the poor sound effect of hearing aids What about? Here’s your answer:

1. Background noise of hearing aid

Background noise has a great influence on the users with better hearing or part of better frequency. At the same time, we must distinguish the difference between the environmental noise and the background noise. The small noise is amplified enough, but the normal people will sound noisy, and feel it is noise.

2. Frequency response range of hearing aids

We know that the audible frequency range of normal human ear is 20Hz-20KHz, and the frequency range of speech is 200hz-8khz. The wider the hearing aid frequency response, the less likely it is to feel the horn sound, and the more natural and realistic the sound will be.

3. Response speed of hearing aids

Slow response leads to soft sound, weak feeling, weak voice and echo. The sense is more obvious in people with better bone conduction or low frequency. Generally speaking, the low frequency response speed of sound is slower than that of high frequency. So some hearing aids users who have good low-frequency hearing and poor high-frequency hearing are more likely to feel echo, which leads to unclean and unclear sound.

4. Nonlinear distortion of hearing aids

It includes the distortion caused by digital processing technology, nonlinear amplification and some noise reduction.

5. Compression technology

Is fast compression good or slow compression good? Fast and slow compression has its own advantages. Generally speaking, slow compression technology is more conducive to the best linear reduction of language, with strong contrast and high definition of language signal. However, in some specific occasions, fast compression must be used.
