Method to Evaluate Aerodynamic Bogie Noise from Shinkansen High-speed Trains by Considering Acoustic Fields
Aerodynamic bogie noise was quantitatively estimated at a wayside observation point by using spatial distribution of the sound pressure level (SPL) obtained by a two-dimensional microphone array in a wind tunnel test. In order to evaluate the SPL, it is necessary to appropriately consider noise generation and sound field with respect to various acoustic properties such as ground reflection and insertion loss of a bogie side cover. In this study, the transfer function between the integrated spatial distribution of SPL and results obtained by an omnidirectional microphone were calculated using a numerical method. The SPL of aerodynamic bogie noise of Shinkansen trains can be estimated using this transfer function and compared with the results obtained in field tests.
