PROBLEM TO BE SOLVED: To provide an on-vehicle acoustic system by which a driver is surely notified of an audible alert of an emergency vehicle or the like outside of a vehicle and the driver is enabled to intuitively recognize the azimuth of a sound source of the audible alert relative to the vehicle per se.SOLUTION: An on-vehicle acoustic system 10 includes: a sound acquisition section 11 for acquiring the audible alert outside of the vehicle; an azimuth calculation section 12 for calculating the azimuth of the sound source of the acquired audible alert relative to the vehicle; and an output control section 13 which instructs a speaker in a direction where the sound source of the audible alert is located, to output an audible alert notification sound on the basis of the calculated azimuth. Thus, the driver is surely notified of the audible alert of the emergency vehicle or the like outside of the vehicle, and the driver is enabled to intuitively recognize the azimuth of the sound source of the audible alert relative to the vehicle per se.

    【課題】車外の緊急車両等の警報音を運転者に確実に通知するとともに、その警報音の音源が自車両に対してどの方位にあるかを運転者に直感的に認識させることが可能な車載用音響装置を提供する。【解決手段】車載用音響装置10が、車両の外部の警報音を取得する音声取得部11と、取得された警報音の音源が、車両に対してどの方位にあるかを算出する方位算出部12と、算出された方位に基づいて、警報音の音源がある方向のスピーカーに対して警報音通知音声を出力するよう指示を行う出力制御部13とを備えることにより、車外の緊急車両等の警報音を運転者に確実に通知するとともに、その警報音の音源が自車両に対してどの方位にあるかを運転者に直感的に認識させることができる。【選択図】図1
