Measurement Of Structure-Borne Noise From Road Input In A Motor Vehicle Cabin

Vehicle interior noise has been an important aspect to determine quality of a vehicle since it affects the level of acoustic comfort of the passengers. This paper proposes a simple noise measurement technique to quantify the contribution of the structure-borne noise due to tire-road interactions. A...
