315 Reducing Noise in Strongly Coupled Acoustic/Structural Enclosure by Active Noise Control and Active Vibration Control

Abstract

This paper concerns the minimization of acoustic potential energy in a strongly coupled acoustic/stuructural enclosure using both active noise control (ANC) and active vibration control (AVC). A target enclosure is composed of rigid walls and flexible panels that are subject to external forces. Optimal feedforward control law to minimize the acoustic potential energy situated at arbitrary locations. Then, Numerical simulation is carried out, demonstration the control effect for minimizing acoustic potential energy using ANC and AVC.
