Abstract

A double panel structure, which consists of two panels with air in between, is widely adopted in many applications such as aerospace, automotive industries, and buildings due to its low sound transmission at high frequencies, low heat transmission, and low weight. Nevertheless, the resonance of the cavity and the poor sound transmission loss at low frequencies limit the double panel’s noise control performance. Applying active structural acoustic control to the panels or active noise control to the cavity has been discussed in many studies. In this thesis, the resonances of the panels and the cavity are considered simultaneously to further reduce the transmitted noise through an existing double panel structure. Various control strategies have been compared and developed to improve the noise control performance. Both numerical and experimental studies are presented.
