Railway noise barriers: Measurements and Simulations

Abstract

Trains Trains passages passages generate generate aa very very annoying annoying noise noise toto the the inhabitants inhabitants ofof their their environs environs.. To To reduce reduce this this annoyance annoyance, noise noise barriers barriers are are installed installed near near several several railway railway lines lines.. Nowadays Nowadays, acoustic acoustic simulation simulation programs programs are are used used inin order order toto optimize optimize the the design design ofof the the acoustic acoustic barriers barriers. These These programs programs use use mathematical mathematical models models toto characterize characterize ththe i noise source andd tto predict di t ththe soundd propagation
