Abstract

Traffic noise is likely to continue as a major issue and become current significant noise problem especially in densely populated cities like Hong Kong. As the noise level keeps on increasing, opening the windows for natural ventilation has become nearly not possible. In the present study, a façade window with staggered design, called as plenum window which can provide better sound insulation with concern about natural ventilation was investigated using two-dimensional computer simulations. The influences of difference sound incidence angles onto the staggered design of the window are studied. Fully opened window is used as reference case to compare the acoustical benefits with plenum window. The results show that the insertion loss of plenum window is affecting by its staggered design and orientation of the window.
