DIN 25008

Railway Vehicle Noise & Silencer Testing

DIN 25008 establishes standardized acoustic measurement procedures for evaluating noise emissions from railway vehicles and their components, including silencers and mufflers. This test quantifies airborne and structure-borne noise sources on trains, trams, and rail infrastructure to assess compliance with EU noise limits for rail transport. Railway manufacturers, operators, and suppliers require accredited testing to validate noise reduction technologies and demonstrate regulatory compliance. Accreditation ensures consistent measurement methodology across the rail industry, supporting fair comparison of technologies and verification of type-approval requirements. This standard is essential for achieving EU noise targets for rail transport.

What it measures

  • Pass-by noise levels from railway vehicles
  • Silencer/muffler attenuation effectiveness
  • Stationary noise from train sources
  • Frequency spectrum of railway noise
  • Structure-borne noise transmission
