The current state of low-frequency noise radiated from a high-speed train was examined through field experiment based on the manual for measuring low-frequency noise which was issued by the Ministry of the Environment of Japan in October 2000. The measurements were done at a Shinkasen tunnel portal and at a Shinkansen viaduct in an open section by using a low-frequency sound pressure level meter (NA-18A) manufactured by Rion Co., Ltd. From the results obtained are the G-weighted sound pressure level, spectra of 1/3 octave band sound pressure level, and dependency of the maximum G-weighted sound pressure level on train velocity.
