Low Frequency Aerodynamic Noise from High Speed Trains

Last updated on 11 June 2018 3:01

Aerodynamic and bridge noise originate from pressure fluctuations generated by high-speed trains in open sections without tunnels. In this study, field tests using a linear microphone array were conducted in order to clarify low-frequency aerodynamic sources of noise below 100 Hz. In addition, a scale-model experiment using a launching facility...
