摘　　要：声屏障是降低交通噪声等流动性声源的一种有效而经济的方法。通过分析声屏障的降噪原理,研究和探讨不同声源状况的声屏障插入损失计算模型以及城市主干道声屏障的声学设计方法,选择噪音超标的校园作为研究对象,根据得到的插入损失计算模型对所选校园设计出相应的声屏障,并对声屏障进行验证,结果表明所设计的声屏障具有良好的隔声降噪效果。Noise barrier is a kind of effective and economical method to reduce traffic noise.By analyzing the theory of the sound barrier＇s noise reduction,researching and exploring the sound barrier insertion loss calculation model of the different sound source as well as the acoustical design methods of the noise barrier of the urban trunk road,according to the insertion loss calculation model,the corresponding sound barriers were designed for the selected schools,through proving the sound barriers,the results show that the sound barrier have good effect of noise reduction.
