Abstract
In this research, noise of the Korean high-speed train running at different speed from 150 to 300 km/h was measured by using microphones and the difference of sound pressure according to its driving velocities was analyzed. In addition, sound pressure characteristics of front, pantograph, bogies and between-car sections of the Korean high-speed trains were deduced by applying delay and sum beam-forming method using a microphone array. From the research, the effects of locations of the high-speed train were investigated. The results of this research can be utilized to reduce noise of a high-speed train.
