How do Noise-Canceling Microphones Work?

 

Have you ever wondered how noise-canceling microphones work? This brief product video from Icom provides the answer.

Icom’s advanced F7000 Series P25 radios, along with select IDAS models like the F3400D boast cutting-edge noise-canceling microphone technology. Icom achieves noise canceling through the AMBE+2 vocoder, distinguishing between speech and background noise, converting the former into a binary code transmitted via FSK (frequency-shift keying) modulation. Unlike traditional analog radios that transmit speech and noise without filtration, Icom ensures crystal-clear communication.
