Influence of rubber hardness on tyre rolling noise

Investigation of the perception of tyre noise is gaining momentum recently due to the implementation of Electric vehicles. This is because the EVs are noiseless and could lead to a compromise in pedestrian safety and interior noise. In this work, the influence of rubber hardness on the tyre rolling noise is discussed and simulated using FE up to 1 kHz. It was observed that variations in rubber hardness alters the characteristics of tyre rolling noise. As a future study, these noise files will be subjected to psychoacoustic tests to analyse the tyre noise for their perception by vulnerable road users.
