高速公路声屏障降噪声场的分布特性

Sound Field Distribution Character of Sound Arrester Degrading in High Way

通过对高速公路侧向有、无声屏障状态下的声场分布测试与分析 ,旨在揭示高速公路声屏障降噪声场的分布特性 。

Through monitoring with sound arrester and without sound arrester, analyses the sound field distribution on the side of high way, discover the sound field distribution character for the purpose of advising the scientific methods of sound degrading design and checking.
