线声源下小型声屏障在隔声窗中的应用

Application of Small Sound Barrier in Sound Insulation Window on Line Sound Source

结合道路交通的发展趋势及噪声特点,针对临街高层住宅的通风隔声窗问题进行研究。主要分析了在线声源交通噪声前提下,小型隔声屏障在顶部通风凸窗上的可行性,在模拟了实际临街高层住宅噪声特点的前提下,进行了有效的理论推导,并得出了小型声屏障在此类特定前提下的可行性、局限性和适应范围。

Considering the development trend and characteristics of road traffic noise, this paper studied the ventilation and sound insulation window for street high-rise residential buildings. Specifically, the feasibility of utilizing small sound barriers at the top of the ventilation bay windows was analyzed under the premise of line source traffic noise. The actual street noise characteristics of the high -rise residential buildings were simulated and effective theoretical derivation was performed. Conclusions were drawn regarding the feasibilities, limitations and applications of utilizing the small sound barriers under the soecified conditions.
