摘要: Effective aircraft interior noise reduction measures require an in-depth understanding of the operational and vibration fields as well intrinsic system characteristics. The former requires detailed mapping in-flight sound responses, whereas latter proper modelling vibro-acoustic behaviour. is discussed in this paper where frequency-domain identification applied to acoustical transfer functions, measured a fully-trimmed cavity.
