Abstract
The noise produced by the vibrating window is commonly caused by nearby transient noise sources such as road traffic, construction work, and the take-off and landing of airplanes. It is known that proper stiffening treatments may improve the sound insulation of windows. In this study, the transient vibration and sound radiation (TVSR) of a window with stiffening treatments is investigated using the time-domain finite element method (TDFEM) and time-domain boundary element method (TDBEM). A stiffened-plate element was developed in this method, which allowed the window to have arbitrary elastic boundary conditions and arbitrarily located stiffeners. Numerical studies of the effects of various stiffening conditions on the TVSR of the window are carried out. The results can be used to guide the design of windows with better transient vibration and noise isolation performance.
