Acoustic Studies of Colloidal Suspensions and Marine Sediments. I. Theoretical Considerations and High Frequency Measurements.
Abstract
The propagation of sound in concentrated colloidal dispersions and marine sediments has been theoretically examined with particular attention to the influence of the interfacial phenomena. In addition to the heretofore identified factors which may effect the propagation of sound in sediments, a possible new effect, heterodeflocculation of various mineral grains, was experimentally demonstrated. The contribution of the interparticle forces to the acoustic particles in sediments is discussed. The treatment of absorption and velocity with the interparticle forces taken into account using the D.L.V.O. theory do not lead to of such forces in a simple geometry of particles, although the assumption of small flocs increases the estimated influence considerably.
