Summary:

The propagation of sound from a small source over the ground, considered as an impedance boundary, is discussed theoretically and compared with measurements over short grass and asphalt. Interference phenomena relevant to the measurement configurations in SAE standard procedures for testing vehicles are emphasized. The effect of the ground impedance on propagation at the longer distances relevant to airport and highway design is also discussed
