예측식을 이용한 철도방음벽의 성능평가에 관한 연구

초록

Railway noise barrier is generally used with welding of joint rail for railway noise reduction in our country. In this study, method for performance evaluation of railway noise barrier using insertion loss was suggested in case of without having noise measurement results before barrier installation. For this, railway noise measurements were performed in commercial high-speed railway site which has railway noise barrier. As a noise level before noise barrier installation,predicted noise level were used. From this method the performance evaluation for railway noise barrier were performed accurately and efficiently.
