After the opening of Kyong-Bu High Speed Railway, tremendous change was occurred in the various realm in Korean Society. But in the Daegu-Busan section, KTX was still running on the conventional line where the railroad was improved to more straightly. For the noise prediction of KTX train which runs on the conventional line, components of noise source were analyzed using SEL(Sound Exposure Level) of meassured data. For the validation of suggested prediction equation, the predicted result was compared to the measured.
