AuWiS – Audiovisual recording and reproduction of traffic noise for the simulation of sound insulation measures

The aim of the project was a realistic audiovisual analysis, simulation and reproduction of railway noise as well as noise insulation measures. By means of spatial visualization and auralization train passings and variable noise insulation was to be made virtually tangible. The focus was on the development of new, cost-efficient and versatile methods and tools, which can also be used in interactive applications. In order to enable dynamic simulations, innovative audio recording methods were developed, with which sound fields can also be correctly reproduced for various immission or listener positions. Interactive simulation models for various noise insulation measures were also to be developed in order to be auralized in real-time. By implementing computer-generated, audiovisual simulations and the use of cost-effective reproduction formats such as VR glasses or tablet applications, affordable and versatile simulation systems were developed for future use in the areas of noise assessment and noise planning.

Fraunhofer IDMT was responsible for the auralization of railway traffic noise as well as for the acoustic simulation of noise insulation measures. For this purpose, suitable audio recording methods were developed and applied, the acoustic effects of noise protection measures are derived, and the auralization was implemented in an object-based reproduction system.
