Vibroacoustical Identification of a Double Wall Panel

摘要

This paper focuses on the identification of the structural modal behavior of double wall panels, as well as the acoustic mode shapes in the cavity between the walls. Additionally the model of a whole panel including dynamics of sensors and actuators used for active control was identified. This general state space model was used to design a control system to improve sound transmission of a double wall panel around mass-air-mass resonance.
