Measuring Tyre Rolling Noise at the Contact Patch

Abstract

The paper describes the development of the measuring device used to measure rolling noise at the tyre/road interface at the Institute of Road Structures, Faculty of Civil Engineering, Brno University of Technology. The measuring device combines a lightweight and a simple construction of American OBSI devices together with parameters of the CPX method used solely in Europe. This solution allows easy and fast mounting and demounting onto the measuring vehicle. The measuring device is used to the noise comparison of different wearing courses and different road equipment, like road marking.The paper describes the development of the measuring device used to measure rolling noise at the tyre/road interface at the Institute of Road Structures, Faculty of Civil Engineering, Brno University of Technology.
