Activities in acoustics

Abstract

Approaching high-speed railway vehicle acoustics as a corporate multi-domain task. Increasing the attractiveness and society's acceptance of rai! transport is defined as an important aspect within the overarching aims of the Next Generation Train (NGT). Due to their impact on passengers and residents, external noise emissions and internal structure-borne and airborne sound transmission, are fundamentally undesirable properties of rai! vehicles. An ambitious project such as the NGT must thus place increased emphasis on the avoidance and reduction of noise and vibrations. Furthermore, from an economic perspective it appears attractive to counter acoustic issues as close to the source as possible and not to rely on infrastructural noise reduction measures.
