Acoustic reflections from undulating surfaces

We recently investigated the behavior of acoustic wave reflection in a medium with a single rough interface with acoustic speed [Formula: see text] and density[Formula: see text] above (below) the interface (Lerche and Hill, 1985). We used mean‐field techniques (Howe, 1971; Karal and Keller, 1964; Frisch, 1968) to find a closed‐form expression for the mean reflected field, and in particular we examined the case where the roughness is on a much smaller scale than the wavelength of the incident energy. We derived a closed‐form expression which is accurate to second order in roughness height.
