患者在佩戴助听器的过程中，通常会遇到觉得助听器音质不好，总是有噪音，而且还伴随着耳鸣，从而造成佩戴助听器不舒服的情况，Jinghao助听器提醒您购买助听器一定要选择较好的，值得信赖的品牌助听器，保证质量，那么一般有哪些原因会造成助听器音效不好呢?以下为您解答:
1, hearing aid background noise
Background noise has a great impact on users with better hearing or better frequency. At the same time, it is necessary to distinguish the difference between ambient noise and background noise. The small sound amplification is sufficient, but normal people will sound very noisy and feel noise.
2, frequency response range of hearing aids
We know the frequency range that can be heard by normal human ears: 20Hz-20KHz, the frequency range of speech: 200Hz-8KHz. The wider the frequency response of the hearing aid, the less likely it is to feel the horn, and the more natural the sound is, the more realistic it will be.
3, hearing aid response speed
The slow response speed makes the sound sound soft, the feeling is not strong, the sound is faint, and it is easy to produce echo. People with better bone conduction or low frequency are more obvious. In general, the low frequency response speed of the sound is slower than the higher frequency response. Therefore, some hearing aid users with low frequency hearing and high frequency difference are more likely to feel the echo feeling and the sound is not clean and unclear.
Nonlinear distortion of 4 and hearing aids
These include distortion caused by digital processing technology, distortion caused by nonlinear amplification, and distortion caused by some noise reduction processing.
5, compression technology
Is it fast compression or slow compression? There are advantages in speed compression. In general, slow compression technology helps linear language reduction, language signal contrast and high definition, but in some specific occasions. It is necessary to use fast compression.
