Comprehensive testing

In preparation for the extensive tests in the coming days and weeks, the first preliminary acoustic tests were recently carried out on the test track of the Institute for Automotive Engineering (ika).

HEAD acoustics GmbH and the ika equipped two different electric vehicles with measuring equipment and carried out near and far field measurements of tyre/road noise. An acoustic camera for high-precision localisation of the sound sources and microphones on the vehicle were used.

The aim of the measurements is to collect data for models of tyre-road noise. The models are being developed as part of the BaLSaM research project. Together with other models of the dominant vehicle noise sources, data is generated that is used by the Institute of Hearing Technology and Acoustics (IHTA) as the basis for a sound propagation simulation.
