- A number of propagation phenomena which cause variability in the noise testing of vehicles using standard procedures have been isolated and studied. Included are the effects of interference produced by reflection from various ground surfaces, the effects of refraction caused by wind and temperature gradients in the atmosphere, changes in sound level due to the wake of the vehicle, and the effects of normal atmospheric turbulence.
