Scatter of Structureborne Noise in Four Cylinder Motor Vehicles 860431
Scatter of the structureborne component of interior noise can be as high as. 15dS for nominally identical vehicles. A hybrid analytical and experimental model of structureborne noise generation has been employed to evaluate the scatter problem, and it is shown that the essential features of structureborne noise scatter are reproduced using this technique. Structural - acoustic transfer functions may be used to characterise the nature and extent of structureborne noise scatter.
