Abstract:In this paper, a new type of sound barrier based on microperforated panel structure with top absorbing cylinder is presented, and the acoustic property of this barrier is studied in detail both in laboratory and in situ. With the barrier installed on the inner city viaduct, tests show that it could reduce traffic noise by more than 7dB(A)
Keywords:microperforated  panel structure  sound barrier  inner city viaduct
