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 performance of noise reduction. So we evaluate the performance of the noise reducers and compare the results. Results of the field tests show that the insertion loss due to the noise reducers is up to 10.6 dB.
