초록
Reduction of the propagation noise generated during pass-by of KTX by noise barrier was measured and analysed fur the two kinds of top-shaped noise reduction devices; one as a plywood board and the other as a PVC pipe were placed periodically. The height and length of reference noise barrier are 2.4 m and 50 m, respectively. The noise reduction with and without noise reduction devices was investigated. (omitted)
