Abstract

Time-domain acoustic contrast control method using loudspeaker array has been studied for generating bright and dark zones in personal audio system. Acoustic contrast which is defined as the acoustic energy ratio between bright and dark zones can be inevitably influenced by the uncertainties in the frequency response of loudspeakers. In this paper, a robust extension of broadband acoustic contrast control with response variation is proposed through exploiting knowledge of the statistical model of the uncertainties. Its performance is evaluated by Monte Carlo simulation method and compared with other acoustic contrast control methods. Simulation results show that better contrast over the continuous frequency range can be achieved using this proposed method.
