The Korean high speed train(KHST), developed since 1996, is presently undergoing commissioning tests on the high-speed track as well as on the conventional track since 2002. The purpose of the commissioning test is twofold: first to verify the performance of the train-set and equipments, and to demonstrate system reliability. Last December, KHST has reached the maximum speed of 350㎞/h and a number of data proving the performance of the train has been acquired. Among the data noise level and pressure variation in a cabin are important factors effecting passenger"s comfort. Discussed in this paper are interior noise and pressure variation when the train passes tunnels during the 350㎞/h test.

In order to develop a high speed train, various conditions have been considered. Internal noise level of cabins is an important one. In this study, The specification of the interior noise level for KHST(Korean High Speed Train) has been adopted the same level of KTX-spec. In this paper, the interior noise levels of KHST are measured and analysed through the speed and other conditions. According to the speed, the level of internal noise(driver"s room(PC2), motorized trailer(TM1) and trailer car(TT2)) is compared. The results of measuring data show that the interior noise levels of KHST are good. And noise levels of this paper are useful in the decision of noise specification.
