The noise emission from passenger trains at high speed has been determined at 7.5 m and 25 m distances at speeds between 130 and 160 km/h. The measurements were carried out according to ISO/DP 3095 and the train was in regular operation between Stockholm and Gothenburg. The measured data have been used to supplement the Nordic prediction method for railway noise. The results indicate that the maximum A-weighted sound pressure levels generally are 4-5 dB below and 8 dB below those of the Nordic prediction model for IC/CE-trains and X2 trains respectively. The equivalent continuous sound pressure levels are 7 dB lower for IC/CE-trains and 9-11 dB lower for X2-trains. The maximum noise emission occurs in the 1600 Hz 1/3 octave band compared to the 1000 Hz octave band for passenger trains at speeds lower than 140 km/h in the Nordic prediction method.
