Abstract
The propagation of plane, infinitesimal acoustic waves through fog media is studied theoretically using a continuum formulation. It is shown that the correction of theories previously published decreases the effects of mass transfer between vapor and droplets and produces lower attenuation and dispersion predictions. General features of attenuation and dispersion phenomena as functions of fog and sound frequency parameters are otherwise unchanged. Correction of the theory improves the agreement between attenuation predictions and experimental measurements.
