abstract = "Noise occuring due to the structural / acoustic characteristics of the space formed by the combination of tires and wheels in the frequency range of 200 Hz to 250 Hz is called cavity noise. Requirements of car makers regarding cavity noise are continuously getting tighter, and accordingly,
many researches related to cavity noise have been conducted. In this paper, we describe what concept profiles should be applied to reduce resonance. First, three FE models with different profile shapes were created and analyzed. Second, a mechanism hypothesis that can describe generation of
cavity noise was established. Based on the mechanism hypothesis internal pressure, displacement change, and force transmissibility we analyzed using an analytical model. Finally, we found parameters that can represent cavity noise in the analytical model. These theoretical results and parameters
were compared with the results of the cavity noise analysis obtained for a real tire.",
