블루투스 오디오 모듈 ANC Technology for Bluetooth Headset

요즘에는, the Bluetooth headsets are becomming a crucial part in our life. And for this type of product, ANC technology is a key factor when it comes to noise cancelation.

What is ANC technology?

ANC refers to Active Noise Control, which actively reduces noise. The basic principle is that the noise reduction system produces reverse sound waves equal to the outside noise, neutralizing the noise. Figure 1 is a schematic diagram of a feedforward active noise canceling earphone. The ANC chip is placed inside the earphone. Ref mic (reference microphone) collects ambient noise on the earphones. Error mic (Error Microphone) Collects the residual noise after noise reduction in the earphone. Speaker plays the anti-noise after ANC processing.
