An Analysis of the Pass-by Noise Reduction for KTX by Noise Reduction Device
소음저감 장치에 의한 KTX 차량의 운행소음 저감량 분석
- Published : 2002.11.01
Abstract
Reduction of the propagation noise generated during pass-by of KTX by noise barrier was measured and analysed for 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.
