Abstract
A theory is presented to describe the acoustic properties of high concentration clay suspensions in terms of the long range electrical forces between the clay particles. The equation describing the attenuation of compressional waves in low concentration suspensions, derived by Urick [2], is extended to cover high concentration suspensions. The constants of the new equation are obtained from Urick's experimental results and it is shown that the equation predicts the attenuation coefficient of clay suspensions over a wide range of concentrations (0 to 40 per cent) and frequencies (10 to 1000 kHz).
