MEF AuWiS - Audio-Visual Capturing and Reproduction of Traffic Noise for the Simulation of Noise Mitigation Methods

Fraunhofer MEF-program

Duration: January 2017 – December 2018

Project “AuWiS” focusses on the development of solutions for realistic capturing, reproduction and simulation of traffic noise and noise mitigation methods. Following issues will be addressed:

  • For high quality simulation of traffic noise and noise mitigation methods, specialized solutions for acoustic capturing are needed.
  • Currently used audio capturing systems are complex and expensive.
  • Currently, only reproduction of the sound field at the chosen microphone position is possible.
  • Thus, only static reproduction and simulation are possible.
  • Based on our experiences with complex capturing systems, we will develop a method that will allow for changes in the virtual listening / microphone position.
  • Based on those capturings, state of the art real-time simulation of noise mitigation methods will be implemented to allow for interactive reproduction.
  • In combination with high quality immersive video reproduction system, an interactive audiovisual environment for close-to-life evaluation of traffic noise and noise mitigation methods will be developed.

The extensive experience of the Vision & Imaging Technologies department in the field of panoramic video & audio capturing will foster development of a flexible audio capturing and simulation system suitable for a wide range of applications.

AuWiS objectives

  • Development of a compact acoustic capturing setup for high quality and flexible use in combination with interactive reproduction systems.
  • Integration of real time processing for interactive simulation of noise mitigation methods
  • Real time video playback and / or rendering for immersive audio-visual environments such as VR and Multiscreen-systems will be implemented and combined with high quality, interactive audio reproduction.

Solution approach

  • Comparison of different capturing methods
  • Development of interactive acoustic simulation tools
  • Implementation of visual simulation environments
  • Practical tests and validation
  • Setup of an interactive, audio-visual reproduction environment
