acoustic railway monitoring system:

a new benchmark for the measurement of noise generation from rail bound vehicles

The acramos system is able to measure pass-by noise and ground borne vibrations from trains in day-to-day operation automatically and vehicle selectively. The range of applications is wide. acramos has been used now for some years and was able to prove its reliability and cost efficiency for

  • the proper assessment source related noise mitigation measures
  • railway noise monitoring with the focus on train operation and management
  • the forecast and identification of trends in environmental noise emission.

If railway noise monitoring wants to serve the needs of modern track management, it has to produce reliable and traceable results even under adverse environmental and operational conditions.

In the past it was not really possible to collect a sufficient amount of data due to the high cost of a manned measurement site. The modern fully automated multi-channel measurement system acramos offers a big number of different noise and vibration indicators as well as meta information such as train category, velocity, noise levels, spectra etc. This sort of analysis is able to provide the necessary amount of high quality data which is necessary to draw the right conclusions.
