Abstract: Noise, vibration, and harshness (NVH) are synonymous with quality factor in automotive engineering. This quality factor is influenced by the internal noise such as engine noise, and external noise such as aerodynamic noise and tyre-road noise. Whereas many studies have been done to identify noise sources and reduce the noise and vibration transmission from the engine and aerodynamic sources to the passenger compartment, the tyre-road noise reduction outside the compartment still remains challenging. It is known that the exterior tyre-road noise being regulated by European legislation under ECE R117 and EC R661/2009 but for the interior tyre-road noise, it is only regulated by market requirement (consumer orientated). Wheel-tyre structure and tyre acoustic cavity resonances have been identified in literatures as the culprits. In this paper, a comprehensive review will be made to tyre-road noise studies and specifically to the acoustic cavity resonance effects and countermeasures.
