Abstract: This paper presents a theoretical study on noise transmission control through double-glazed windows. Acoustic resonators are incorporated into the window to reduce sound pressure level in the air cavity at the targeted frequencies, thus attenuating the fluid loading on glass panels to enhance the sound transmission loss. A vibroacoustic model, representing the interaction between the panels, air cavity, and acoustic resonators, is developed. The sound transmission loss through the window is classified into three categories in terms of coupled and uncoupled structural and acoustic modes, i.e., acoustic-mode dominant, structural-mode dominant and coupled-mode dominant. The controllability of acoustic resonators for each category is examined in detail, leading to a set of criteria for determining the locations of the resonators. Numerical results are presented to demonstrate the significance of using multiple acoustic resonators in broadband noise transmission control for double-glazed windows.
