Noise characterization of high speed

Characterization of the noise coming from the pantographs (LEAM UPC), in collaboration withSENER, through a self-developed array of microphones, allowing the measure ofinsulation from the roof rail cars, and soensure their indoor comfort. The results of this study have been applied to high-speed trains (up to 250km/h).
