What is the difference between single microphone and dual microphone for hearing aids?

Author:admin AddTime:2021-09-06

There are 2 types of hearing aid dual microphones:

1. The dual microphone ports receive signals at the front and rear positions respectively, and the two signals are transmitted into the microcomputer in the movement. The computer determines the direction according to the time difference between the sound signal reaching the two microphones, etc.

2. The two microphone systems in the TM system are arranged horizontally, and the method of delay and cancellation is applied, and the chip finally realizes the directivity function. The dual microphone circuit is more complex, the chip speed is faster, the technical content is higher, and the price is slightly higher. Mainly when dealing with changing and complex sound environments, it automatically selects omnidirectional or directional microphones to improve the signal-to-noise ratio and perform better.
