PROBLEM TO BE SOLVED: To correctly determine a state of a sound environment in a cabin and properly control magnitude of sound of a noise generation source.SOLUTION: A sound environment adjustment device 300 comprises: a sound collection device 330 for collecting sound in a cabin and outputs a sound signal; an acquisition unit 322 for acquiring a rotation number of a fan 113 as an operation amount according to an operation of a user to an air conditioner 100 as an on-vehicle noise generation source; a determination unit 323 for determining whether or not an index indicating a state of a sound environment in the cabin exceeds a reference on the basis of the sound signal and the rotation number of the fan 113; and a control unit 320 for, when it is determined that the index indicating the state of the sound environment in the cabin exceeds the reference by the determination unit 323, controlling the rotation number of the fan 113 for reducing magnitude of the sound of the air conditioner 100.SELECTED DRAWING: Figure 1
【課題】車室内の音環境の状態を正確に判定することができ、雑音発生源の音の大きさを適切に制御すること。【解決手段】音環境調整装置300は、車室内の音を集音し、音信号を出力する集音装置330と、車載された雑音発生源としてのエアコン100に対する利用者の操作に応じた動作量としてのファン113の回転数を取得する取得部322と、音信号とファン113の回転数とに基づいて車室内の音環境の状態を示す指標が基準を超えたか否かを判定する判定部323と、判定部323により車室内の音環境の状態を示す指標が基準を超えたと判定された場合、エアコン100の音の大きさを低減させるようにファン113の回転数を制御する制御部320と、を備える。【選択図】図1
