Performance Test of Noise Reducers Installed on Noise Barrier
방음벽 상단의 소음감소기 성능 평가
Abstract
The use of noise barrier is being increased to reduce the environmental noise in these days. Also, many noise reducers installed at the top of noise barrier are developed for improving the efficiency of noise reduction. So we evaluate the performance of the noise reducers and compare the results among the others. Results of field tests show that the insertion loss due to the noise reducers is up to 10.6 dB.
