Abstract : The effects of a high concentration of particulate matter held in suspension in water on the propagation of an acoustic wave in water is discussed. Expressions for the average wave speed, average pressure, and incoherence of the pressure field are obtained for an incident harmonic pressure wave on a large number of discrete, suspended scatterers in water. The wavelength of the wave is assumed to be large compared to a scatterer diameter. Results are compared with experiments of acoustic wave propagation in sand-water mixtures. (Author)
