Railway noise is one of the main causes of environment impact. Whenever a new railway line is planned or a housing project near an existing railway is proposed, an estimate of the relevant noise levels is usually required. For this, it is necessary to quantify those parameters that affect the railway noise. Therefore we investigated the noise level which subway trains generated passing through the block of test railway track between Hopo and Keumgok station in Busan. This paper shows the status and characteristics of the subway train noise and a subjective evaluation.
