摘要
The invention relates to an audio signal processing apparatus (100) for processing an input earpiece audio signal (x) upon the basis of a microphone audio signal (y), the audio signal processing apparatus (100) comprising a voice activity detector (101) being configured to determine a voice activity indicator signal (xvad) upon the basis of the input earpiece audio signal (x), a noise magnitude determiner (103) being configured to determine a microphone noise magnitude indicator signal (wy) upon the basis of the microphone audio signal (y), a gain factor determiner (105) being configured to determine a gain factor signal (ΔG) upon the basis of the voice activity indicator signal (xvad) and the microphone noise magnitude indicator signal (wy), and a weighter (107) being configured to weight the input earpiece audio signal (x) by the gain factor signal (ΔG) to obtain an output earpiece audio signal.
