초록

We test the running performance of KHST(Korean High Speed Train) that is developed in Korea. The interior noise of high speed train is dependent on the train speed generally and is one of the most important problem recently. In this paper, we present the test results of interior noise for KTX and KHST and examine into the cause of interior noise for KTX. From the analysis results, we know that the interior noise of KHST is lower about $2{\sim}5dB(A)$ than KTX and also the noise levels of KTX at 80Hz and 250Hz in tunnel increase very highly.
