Abstract

Microphone array (MA) involves several microphones positioned at diverse spatial locations. According to the sound propagation fundamentals, the multiple inputs can be handled to attenuate or to enhance the stemming signals from specific directions (desired signal) in the presence of demeaning noise sources (Levy et al. in IEEE Trans Audio Speech Lang Process 19(6):1540–1555, 2011 [1]; Doclo et al. in IEEE Signal Process Mag 32(2):18–30, 2015 [2]). This process is based on the known source location information, and the used MA to guarantee hands-free signal as well as noise sturdiness. Traditional classic microphones should be near the speaker either by wearing the microphone or by using movable microphone.
