| Summary: | To improve riding comfort and optimize noise insulation design for high-speed EMUs, the noise source was analyzed, and noise value of high-speed EMUs typical position passenger room was introduced. Noise source under different speed was discussed and indicated mainly from wheel-track noise and pneumatic noise. When the speed of vehicle was under 200 km/h, noise in the passenger room was from wheel-track noise; with the vehicle speed increasing, the pneumatic noise effect was gradually highlighted and became the primary when the speed reached 300 km/h. |
