Structural acoustic modelling of three dimensional enclosed sound fields with active/passive piezoelectric networks
In this paper, analytical effort for modelling piezoelectric-structural acoustic interactions of sound transmission through a flexible smart panel into an enclosure is presented. A spherical wave is transmitted into a rectangular enclosure through a flexible panel, while piezoelectric patches, bonded on the panel, are used as actuators and /or passive dampers. The developed model accounts for panel interactions with both the external and enclosed sound fields as well as the bonded piezoelectric patches, which makes it appealing for a broad field of model-based active, passive, and hybrid noise control schemes.
