ISO 3095:2013 / EN ISO 3095

Railway Pass-By Noise Measurement

ISO 3095 defines the standardized method for measuring and reporting noise emitted by railbound vehicles during pass-by at a fixed observer position. This is the primary standard used to assess compliance with European TSI Noise limits and national environmental regulations for passenger and freight trains. Manufacturers, railway operators, and regulatory authorities depend on this test to demonstrate noise performance, support fleet certification, and document compliance with noise reduction requirements. Accredited laboratories provide the independent, traceable measurements required for regulatory approval and public confidence in noise impact assessments.

What it measures

  • Sound pressure level during pass-by (LAmax, dB(A))
  • Noise emission per axle or per vehicle
  • Frequency spectrum of pass-by noise
  • Time-weighted sound exposure level
  • Noise contribution by vehicle type and condition
