To achieve both clarifying a sound image and enhancement of a wrapped feeling.SOLUTION: An acoustic device according to the embodiment includes a first processing unit and a second processing unit. The first processing unit generates a first acoustic signal which is delayed as the frequency is higher and is output so as to be localized in front of a listener, based on a sound source signal. The second processing unit generates a second acoustic signal which is delayed as the frequency is lower, and is output from the surroundings of the listener, based on the sound source signal.SELECTED DRAWING: Figure 2
【課題】音像の明瞭化および包まれ感の充実化を両立させること。【解決手段】実施形態に係る音響装置は、第1処理部と、第2処理部とを備える。第1処理部は、音源信号に基づき、周波数が高いほど遅延され、聴取者の前方に定位するように出力される第1音響信号を生成する。第2処理部は、音源信号に基づき、周波数が低いほど遅延され、聴取者の周囲から出力される第2音響信号を生成する。【選択図】図2
