Abstract

This document specifies the methodology for measuring equivalent sound pressure levels in octave frequency bands (in
dB rel. 20 μPa), equivalent and maximum A-corrected sound levels (in dB rel. to 20 μPa), generated in the rolling stock in the driver’s cabins and in the passenger rooms of the salons, using acoustic meters - multifunctional analyzers Ecophysics, noise and vibration meters, spectrum analyzers Ecophysics 110A, Oktava 110A Eco, Oktava 110A, Oktava 111, B&K 2250, 2250L, 2270, noise and vibration analyzers ASSISTANT, noise and vibration meters, digital spectrum analyzers Algorithm-05, SVAN979. This methodology is applicable for noise measurements in the driver’s cabins and in the passenger rooms of the rolling stock of both new and old models operated by the underground railway.
