| Abstract(in English) | Active noise control (ANC) utilizes the superposition property of acoustic waves. When an anti-noise wave is elegantly generated to have the same amplitude but inverse phase of the noise wave, it can reduce the noise level at the desired location, where an error microphone is placed to monitor the error signal and make the whole system a close loop control problem. In the case when the error microphone cannot be placed at the desired noise reduction location, virtual sensing techniques are needed. In this paper, we examine one of the virtual sensing techniques in an experiment setup the feedforward ANC system using the parametric array loudspeaker as the secondary source. Experiment results show that improved noise reduction can be obtained at the virtual microphone location. |
