Feedforward multichannel virtual-sensing active control of noise through an aperture: Analysis on causality and sensor-actuator constraints
The multichannel implementation of the auxiliary-filter-based virtual-sensing (AF-VS)
technique for active noise control applications is revisited and realized in the paper.
Frequency-domain analysis based on random primary noise proves that the multichannel
virtual-sensing active noise control (MVANC) technique can achieve optimal control at the
desired virtual locations even if the signals at the physical and virtual microphones are not
causally related. Further analysis on a number of sensor-actuator configurations shows that …
