About of hearing aids

1, For the way the sound is handled

A, Digital hearing aid: The sound can be modified according to the individual’s hearing situation (audiogram) so that the patient can hear the sound. The better the chip, the better the processing power and the better the effect.

1. Analog hearing aid: The sound is amplified in the same proportion, and the sound is not modified too much. However, it is not suitable for most people. Because the sound is amplified in the same proportion, many noises in the environment will be amplified, and the ability to cope with complex environments is very poor. In a noisy environment, it is basically useless, and it is impossible to hear others. Therefore, if the economic ability is worse, don’t buy a machine below 300 yuan (very few people may be suitable). Because it is not only inaudible, but it will damage the patient’s residual hearing.
