Railway Noise and Vibration

Eurailtest performs acoustics and vibration audits to verify the compliance with relevant standards and regulations.

Railway noise and vibration - local residents

Assessing the noise and vibration pollution caused by rail transport.

Objectifs des essais :

  • Characterize situations that can create discomfort for local residents, caused by vibro-acoustic phenomena due to structure-borne underground or ground vibrations
  • Characterize the operation of specific equipment (fans, escalators, air conditioning, air vents, etc.) from an acoustics point of view before and/or after renovation work

Moyens d’essais :

  • Class 1 integrating sound level meters (SOLO type, 01dB-Metravib)
  • Sound calibrators (Brüel & Kjaer)
  • Tri-axial and regular accelerometers
  • Data acquisition system, NetdB by 01dBMetravib or equivalent (4 to 16 channels)
  • Software: dBTrait, dBFA

 Accréditations :

ISO/IEC 17025 awarded by COFRAC

Normes d’essais  :

  • NF S31 010- Acoustics – Environmental noise characterization and measurement – Special measuring methods
  • NF S31 110- Acoustics – Description and measurement of environmental noise – Basic quantities and general evaluation methods
  • NF S 31-088 – Acoustics – Measurement of railway traffic noise with a view to its characterization
  • French decree of 31 August 2006 – Regarding local noise abatement requirements and amending the Public Health Code

 

Noise from industrial sites

Check that noise emitted by industrial sites complies with relevant standards and regulations.

Objectifs des essais :

  • Check at regular intervals, through measurements of ambient and residual noise defined by regulations, that industrial activity does not cause noise pollution for neighbours
  • Qualify the risk of noise-induced discomfort for those living in the vicinity

Moyens d’essais :

  • Class 1 integrating sound level meters
  • Sound calibrators (Brüel & Kjaer)
  • Software: dBTrait, dBFA
  • Measuring masts (up to 40m high)
  • All-weather kits for long-term measurements (7 days)
  • Weather station

 Accreditations :

ISO/IEC 17025 awarded by COFRAC

Normes d’essais  :

  • NF S31 010- Acoustics – Environmental noise characterization and measurement. Special measuring methods
  • NF S31 110- Acoustics – Description and measurement of environmental noise – Basic quantities and general evaluation methods
  • Arrêté du 23/01/1997 – Regarding the reduction of noise emitted into the environment by facilities classified for environmental protection
  • Décret du 31/08/2006 – Regarding local noise abatement requirements and amending the Public Health Code
