The Relationship Between Truck Tire Vibration and Near and Far Field Sound Levels 762021

The paper investigates and proves that measurement of the near field sound and sidewall vibration are comparable to the tire far field noise and thus may be used to reasonably evaluate tire noise characteristics. Other conclusions of the research include: Any two of the three quantities of A-weighted sidewall acceleration near field sound, and peak pass-by sound may be related by a constant for a given road surface and that vibration normal to the surface of the tire is coherent with the tire near field sound.
