    Abstract:
    Using a single scattering approximation, the authors derive equations for the scattering attenuation coefficients of P- and S-body waves. The results are discussed in the light of some recent energy renormalization approaches to seismic wave scattering. Practical methods for calculating the scattering attenuation coefficients for various Earth models are emphasized. The conversions of P- to S-waves and S- to P-waves are included in the theory. The Earth models are assumed to be randomly inhomogeneous, with their properties known only through their average wavenumber power spectra. The power spectra is approximated with piecewise constant functions, each segment of which contributes to the net, frequency-dependent, scattering attenuation coefficient. The smallest and largest wavenumbers of a segment can be plotted along with the wavevectors of the incident and scattered waves on a wavenumber diagram
