Elastic mean free path of acoustic waves in randomly inhomogeneous media

Formulae for the differential scattering cross section and the scattering cross section of unit volume of a random turbulent medium have been derived using the von Karman correlation function of the acoustic refractive index fluctuations. The differential scattering cross section has been studied in dependence on scattering angles, mean scale of inhomogeneities, and the wavelength. The elastic mean free path of acoustic waves in turbulent media has been estimated in dependence on k (DOT) a and the mean square fluctuation of the medium refractive index for acoustic waves.
