International Journal of Vehicle Design (IJVD), Vol. 11, No. 3, 1990

Abstract: The mechanism generating booming noise was investigated through experimentation and numerical analysis. By applying such new techniques as rotating torsional excitation and speckle interferometry, it has become possible to analyse the vibration mode of a tyre under actual rolling conditions. Through the use of these techniques, it was found that the dominant factor producing booming noise was the coupled vibration between the tyres and the powertrain-suspension system. Booming noise can be effectively reduced by tuning the vibration characteristics of these components.
