摘要:
Presented herein are signal processing techniques that integrate an adaptive filtering process with a parametric post-filter in the frequency domain to control the amount of body noise reduction in each of a plurality of frequency bands (e.g., tuneable body noise reduction in each frequency band). The parametric post-filter generates a gain mask that is tuned to responses of sensors to separate external acoustic sounds and body noises, while limiting distortions of own voice. The techniques presented herein can preserve external acoustic sound quality, attenuate own voice to a comfortable level without distortion, suppress body noises, and/or lower a noise floor of the output signal.
