Abstract

The main objective of this study is to develop a novel noise attenuation device which can resolve the conflict of noise and ventilation issues faced by conventional glass or louver windows. Therefore, a sonic crystal (SC) window was designed and was tested in a reverberation room. The effects of the jagged flap on the acoustical performance of the SC window were investigated too in the present studies. In the narrow frequency range of 700 Hz to 1400 Hz, the SC window was able to attenuate 4.1 dBA of white noise which accompanied by 40% of wind speed reduction if compared with the case of without window. From the experimental results, we can conclude that the SC window can improve the sustainability of urban environment due to the good balancing of noise mitigation, natural ventilation and daylighting provided by the window.
