Background Noise Suppression (BNS)
Background noise suppression (BNS) is designed primarily for hands-free operation and reduces background
noise to enhance communication in noisy environments.
Automatic Gain Control (AGC)
Automatic Gain Control (AGC) is applicable to the hands-free operation and is used to keep audio output at nearly
a constant level by adjusting the gain of signals in some circumstances. This increases the effective user-phone
radius and helps with the intelligibility of soft-talkers.
