Active Noise Reduction digital CB Microphone is built with one noise reduction microphone module that based on DSP platform and ARM. The Interior module contains language adaptive filtering algorithm, language intelligent extraction algorithm. Mainly to solve the high noise environment speech communication problem, ensure in high noise environment with high SNR, low distortion, high speech reducibility.
