Abstract [en]

Reducing development time and costs is a never ending challenge in the automotive industry. Development times are decreased by using CAE-tools for early predictions of product performances and qualities and by moving field testing to indoor lab-environments. In the automotive industry, an NVH issue such as road noise is an important factor for the perceived product quality. A useful method to address NVH problems and to reduce field testing is to combine recordings and simulations into auralizations. The objective of this study was to compare auralization of structure borne tyre noise based on operational data against artificial head recordings made under the same conditions. Results from a listening test showed that clear audible differences existed in the auralizations compared to the artificial head recordings. These audible differences were caused by low coherence in the measured binaural transfer functions below 150 Hz and in the frequency range 1000-1600 Hz.
