Tyre noise reduction using damping layers

Tyre noise on highway is proposed to be reduced by a damping layer. When rolling tyres on high way are continuously impacted at the edges of contact areas, vibration will be generated and leads to structure borne noise. The use of the damping layer has been proven useful in suppression of vibration response caused by the impact. The effect of a range of thickness of layers are analysed and calculated with damping magnitudes.
