Vibroacoustic analysis of a clamped finite orthotropic laminated double-composite plate with an air cavity

The objective of this study is to develop a model to describe accurately the vibroacoustic performance of a clamped finite orthotropic laminated double-composite plate filled with air. In this investigation, the theoretical and existing experimental results were compared and reached a good agreement. The influence of several key system parameters (e.g., thickness of faceplate, the thickness of air cavity and the sound incident angles) on sound transmission loss is considered.
