Sound Speed and Attenuation in Multiphase Media

Abstract

One research goal developed from conducted shallow water (SW) acoustic transmission experiments in sandy-silty areas [1] revealed a nonlinear power law frequency-dependent attenuation at lower frequencies ( less than or equal to 1 kHz ) consistent with results reviewed in [2-4] and the observations by the ONR-HEP program.
