Vibration and acoustic insight on high speed trains running on a ballast superstructure

Last updated on 02 September 2014 3:35

A modern parameter in the global quality assessment of high speed trains is the noise emission. An innovative method for the identification and comparison of mobile acoustic sources was implemented: the microphone array. Basis of the method is the "beamforming algorithm” that from a measure of the acoustic pressure in...
