PROBLEM TO BE SOLVED: To provide means for reducing leakage of voice from other hearing positions at hearing of sound sources at each hearing position when the different sound sources are reproduced at the same time in a space having a plurality of hearing positions such as in a compartment of a vehicle.SOLUTION: An acoustic processing device includes: a first input unit into which a first sound source signal is input that is a sound source signal for reproduction at a first hearing position and includes a first Lch signal and a first Rch signal; a first output unit that outputs the first sound source signal to a first speaker group including a first speaker installed in the vicinity of a head position of a listener at the first hearing position; and a signal processing circuit. The signal processing circuit takes out a first common signal common to both first Lch signal and first Rch signal and outputs the first common signal to the first speaker.SELECTED DRAWING: Figure 1
【課題】車室内などの複数の聴取位置が存在する空間において異なる音源が同時に再生される場合に、各聴取位置における音源の聴取において、他の聴取位置からの音声の漏れを低減する手段を提供することを目的とするものである。【解決手段】第1の聴取位置において再生するための音源信号であり、第1のLch信号および第1のRch信号を含む第1の音源信号が入力される第1の入力部と、第1の聴取位置における聴取者の頭部位置の近傍に設置された第1のスピーカを含む第1のスピーカ群へと第1の音源信号を出力する第1の出力部と、信号処理回路と、を備え、信号処理回路は、第1のLch信号と第1のRch信号との両方に共通する第1の共通信号を取り出し、第1の共通信号を第1のスピーカへと出力する。【選択図】図1
