SOME EFFECTS OF ROAD SURFACE MACROTEXTURE ON ROAD TRAFFIC NOISE

This paper was presented at session 30 - noise and environmental studies. Road surface macrotexture is known to affect the level of road traffic noise in various ways. However, little is known about the details or magnitudes of the effects. This paper presents the initial results of an ARRB research project which is investigating these effects. Roadside noise levels are presented as a function of macrotexture, tyre tread pattern and vehicle speed. These data may be used for design. Frequency spectra of the data are shown and used to consider the controversial topic of how the tyre/road noise is generated. The relative importance of the various components of vehicle noise on traffic noise levels is discussed with the aid of the data presented. (Author/TRRL)
