The transport and civil industry research has been aiming at improving vibro-acoustic performance of panel-like structures such as trim panels, glazing windows or separating walls. Focusing on the airborne path, the application of an active control for optimizing the plate acoustic isolation performance is here investigated. A transmission model of an acoustically excited plate is derived in the time domain predicting the plate velocity and its acoustic radiation. The dynamic system is modelled together with the control loop in MATLAB (R) where a suitable control algorithm for enhancing the panel transmission loss performance is developed.

Abstract
The transport and civil industry research has been aiming at improving vibro-acoustic performance of panel-like structures such as trim panels, glazing windows or separating walls. Focusing on the airborne path, the application of an active control for optimizing the plate acoustic isolation performance is here investigated. A transmission model of an acoustically excited plate is derived in the time domain predicting the plate velocity and its acoustic radiation. The dynamic system is modelled together with the control loop in MATLAB (R) where a suitable control algorithm for enhancing the panel transmission loss performance is developed.File | Dimensione | Formato | |
