title: Time-domain acoustic contrast control design with response differential constraint in personal audio systems.
abstract: The acoustic contrast control (ACC) approach is applied to reproduce the focused sound in personal audio systems utilizing an array of loudspeakers. A time-domain design of ACC is developed here for broadband input signals, where a response differential term is introduced to control the frequency response. Based on experimental results in an anechoic chamber, the proposed method demonstrates the potential capability to provide excellent acoustic contrast over the continuous frequency and maintain a flat frequency response. Furthermore, compared with the previous method, fewer parameters need to be tuned in the proposed method.
