Kurzfassung englisch:
While a train is passing through a tunnel, the interior noise level is elevated compared to a track in open country due to reflections from usually fully reflecting walls and track surfaces. The aim of this study was to investigate how speech communication is influenced inside a tunnel at speeds typical for Austria of up to 230\,km/h using the speech transmission index for public address systems (STIPA).
Although for the covered speed range the speech intelligibility is considerably decreased inside a tunnel in absolute terms the STIPA values still indicates a good intelligibility when passengers are sitting in adjacent seats. However, when the distance between speaker and listener is increased, at higher speeds complex information may become difficult to comprehend, depending on the speech level.
