Tire–road interaction noise

Abstract

The relative importance of tire noise to overall vehicle noise is established. A general description is then given of the tire engineering process and of tire structures. The important parameters influencing tire noise are discussed, based on presently available data, followed by an identification of unknown and contradictory areas. The basic mechanisms of tire-noise generation, although not well understood, are investigated largely from a theoretical viewpoint. Areas for future research and development are identified based on gaps in the existing physical data base and a rather primitive level of understanding of noise-generating mechanisms.

Influencing Parameters on Tire–Pavement Interaction Noise: Review, Experiments, and Design Considerations

“…It is often assumed the difference is about 2 dBA in favor of radial tires (Sandberg and Ejsmont, 2002 [1]). Leasure and Bender (1975) [48] indicated that radial tires are 1-3 dB quieter than bias-ply tires. A more important benefit of radial tire is 20-30% reduction of rolling resistance (Ejsmont, 1990 [41]).…”

“…Tire wear might be the most important single tire-related parameter in terms of TPIN (Tong et al, 2013 [50]). Leasure and Bender (1975) [48] reported that tire noise often increases then decreases with wear due to initial flattening of tire curvature and edges, then tread depth reduction.…”

“…These spectral data can be best explained b}" considering the mechanisms by which tire-road interaction noise is generated. As sumirLarized in references [3,17], at present three generic types of tire noise source n.echanisms have been postulatedaerodynamic, air pumping and vibration.…”
