Abstract

Korean High Speed Train (KHST) designed to operate at 350km/h has been tested on KyungBu high speed line since it was developed in 2002. The specification of the interior noise level for high speed train in Korea has been adopted through the contract between KHRC and Korea TGV consortium, not a national specification. But it can not be adopted to KHST designed at 350km/h because this has involved up to 300Km/h. Therefor, in this paper, the interior noise level at 350km/h are predicted in passenger car using the results at 300Km/h and these results show that the KHST's interior noise levels are good up to 300Km/h but need to be reduced at 350Km/h in the view point of limit value at 300Km/h of the contract between KHRC and Korea TGV consortium. Also it proposed to make a national specification for the interior noise level to evaluate it in detail at 350Km/h.
