NOISE TESTING OF TYRES

Noise generated from the interaction of tyres with the road surface is an important component of road traffic noise. Research conducted at TRL on tyre noise generation and propagation is reviewed. The evolution of tyre noise regulations in the European Union is described with reference to the development of a procedure for tyre noise testing and to test surfaces. Understanding the sources of tyre noise is important to reducing tyre noise. Methods have been developed to locate and quantify the sources of tyre noise: the airborne sound quantification (ASQ) method and the spatial transformation of sound fields (STSF) method. These methods were complicated and restricted to test track conditions. A close proximity tyre noise test vehicle, known as TRITON, was developed using a modified 10 tonne-truck. Research conducted to assess the propagation of tyre noise in the region of the wheel arch and the immediate area located between the tyre tread and the road surface is described. This paper was presented at the ITEC Asia 2001 Conference, Busan, Korea, 18-20 September 2001.
