| Abstract: | This paper describes the mechanism of generating tire/road noise, which contributes very much to the vehicle exterior noise, by dividing the factors of the tire/road noise into exciting force, vibration characteristics and acoustic radiation characteristics. In addition, it shows the effectiveness of suppressing the distinctive tread vibration mode, which is the main mode of vibration radiating noise of around 1 kHz with a high sound pressure level in radial tires for passenger cars. |
