Prediction of Close-Proximity Tire-Road Noise from Tire Cavity Noise measurements using a statistical approach

This study is a first step towards reducing the time and the costs needed for standard acoustic measurements for tire homologation or for assessing the acoustic quality of different road surfaces. Our measurement method is namely not influenced by the surrounding buildings and can be used without any interference in the flowing traffic. The costs for the needed hardware are also negligible compared to the conventional exterior noise measurement systems. However, the transferability of the results on the tire test rig to field measurements still has to be checked and will be done in a future study.
