Spectra and Shape of Complex Pulses Reflected from a Slatted Surface

In this paper we present some results which have been obtained by the simulation process, namely, the reflection of pulses from a slatted surface. The result of the reflection of sound from arbitrary surfaces depends, of course, on both differential amplitude and phase shifts over the surface, in addition to differential travel times to the listener or receiver. At this point, all of these factors can be adequately accounted for in a practical fashion by introducing certain measured parameters for the scattering material for attenuation and phase shift and using a cosine scattering law over the surface of the scatterer.
