Využití akustické kamery pro lokalizaci zdrojů hluku železničníchvozidel

This master thesis deals with using acoustic camera with beamforming method for identification and localisation of railway noise sources. On theoretical basis are identified main railway noise sources and its causes. In other part are investigated methods and possibilities of noise measurement focused on acoustic camera. In practical part is measured real train noise moving on test railway track in Velim. On this basis is made detailed analysis of noise sources and according to theoretical background are made some suggestions to decrease raiway noise.
