アクティブ制御によるエンジン音の音色と音像のリデザィン

摘要

統合運動知覚，音源知覚に基づいたェンジン音の情報 性の再構築を目的とするデザインとして以下を示した. ①複合音のスぺクトラ構造において，基音やスぺク トル構成と密度を変化させることで，一様なスぺク トラ構造の連続的ピッチ上昇に対し，ピッチ上昇を 高められ，加速感を高められる.%In this development, the functions of engine sound were considered from the standpoints of the perception of overall vehicle dynamic performance and the perception of the engine sound sources. The engine sounds that emphasize the provision of vehicle information to the driver were designed. The developed technology generates interior sounds that combine original engine sounds with acoustics. Electroacoustic transducers were placed in the vehicle sub cavity to perform appropriate acoustic localization image in the interior in accordance with the engine sound type, Since the type of engine sound varies in accordance with the engine speed range, the designed sound emphasized the changes in timbre and pitch that occur at different engine speeds. The design also accomplished a spatial engine sound by shifting the acoustic localization image. This designs and system are installed in LEXUS GSF.
