Attenuation in Randomly Inhomogeneous Sound Channels.

Abstract

Estimates of the absorption of sound in sea water, based on sound channel experiments, can be seriously affected by scattering from random inhomogeneities in sound speed. Ray diffusion theory leads to an additional component of attenuation independent of frequency. Order of magnitude estimates of diffusion loss, calculated from perturbations in the sound speed profiles, are in reasonable agreement for a broad range of experimental data. (Author)
