PROBLEM TO BE SOLVED: To solve a problem in effective use of resources in which a sound image of a speaker output is localized to people who is not interested in listening to a sound or a music that is being reproduced such as those who are sleeping, those who operate personal mobile terminals, etc. in a case in which there are multiple occupants in the same vehicle.SOLUTION: An in-vehicle sound field control device according to the present invention that controls an audio device having a sound output unit for outputting a music or a sound in a vehicle includes a passenger presence/absence detection unit that detects presence or absence of an occupant in a seat in the vehicle, a sound output necessity determining unit that determines whether sound output is necessary at a seat position where an occupant of a music or sound output by the sound output unit is present when the occupant presence/absence detection unit detects occupant presence in the seat, and a sound field processing unit that localizes a sound image of the music or sound output by the sound output unit with the seat position of the occupant for which sound output is determined to be necessary as a listening point based on the determination of the sound output necessity determining unit.SELECTED DRAWING: Figure 1

    【課題】同一車両内に複数の乗員が居る場合、全員が再生中の楽曲を聞きたいとは限らない場合があり、居眠している者、個人の携帯端末を操作する者等、音声・楽曲を聞くことに興味がない場合があり、そのような者に対してスピーカ出力の音像を定位させてしまうことは車内リソースの有効利用上の課題である。【解決手段】本発明の車載音場制御装置は、車両内で楽曲または音声を出力する音出力部を備えるオーディオ装置を制御する車載音場制御装置において、車両内の座席の乗員有無を検出する乗員有無検出部と、乗員有無検出部が座席に乗員有を検出した場合に、音出力部が出力する楽曲または音声の乗員のいる座席位置に音出力要否を判断する音出力要否判断部と、音出力要否判断部の判断に基づき、音出力要と判断した乗員の座席位置を受聴点として音出力部が出力する楽曲または音声の音像を定位する音場処理部と、を備える。【選択図】 図1
