自動車室内音開発支援システムの開発(Part I 乗り物の音色・音質改善技術,特別オーガナイズドセッション「音色・音質設計技術〜開発者と利用者・第三者を繋ぐ」,振動・騒音改善技術)

抄録

A system for development of sporty interior sound during acceleration was achieved that supports evaluation of interior sound quality, definition of interior sound target and definition of intake noise target. A technique defining an intake noise target was developed with a method, which simplifies the interior sound by separating into three components: a component caused by intake orifice noise, a component caused by exhaust noise and the background noise. An intake noise target is calculated with an interior sound target, a background noise of an original interior sound and a transfer function from an intake orifice to the interior.
