Abstract
A theory of critical ultrasonic attenuation in binary liquids based on the frequency-dependent specific heat is presented. Excellent agreement with experiment, without any adjustable parameters, is found for the frequency dependence of the consolute point attenuation and for the temperature dependence away from the consolute point. The latter is exhibited for two different mixtures at several different frequencies.Keywords
