To enable a passenger to sense notification sound issued in response to an object existing outside a cabin while reducing discomfort.SOLUTION: A notification sound generation device 100 arranged in a vehicle so as to generate notification sound in response to an object existing in the periphery of the vehicle includes: a detection processing section 110 for determining whether a distance is less than a first threshold on the basis of detection signals from sensors 14FL, 14FR, 14RL, 14RR, 16F and 16R for detecting a distance between the vehicle and the object; and a sound processing imparting section 130 for imparting sound processing based on transmission characteristics of sound transmitted from an outside of the vehicle to the cabin of the vehicle to the notification sound when the distance is determined to be less than the first threshold.SELECTED DRAWING: Figure 2

    【課題】車室外に存在する対象物に対応して発せられる報知音を、搭乗者に違和感を低減させて知覚させる。【解決手段】車両に設けられ、車両の周囲に存在する対象物に応じて報知音を発生させる報知音発生装置100は、車両と対象物との距離を検出するセンサー14FL、14FR、14RL、14RR、16Fおよび16Rからの検出信号に基づいて、距離が第1閾値未満であるか否かを判定する検出処理部110と、距離が第1閾値未満であると判定された場合に、車両の外から車両の車室に伝わる音の伝達特性に基づいた音処理を、報知音に付与する音処理付与部130と、を含む。【選択図】図2
