The ultrasonic attenuation coefficients for longitudinal waves in bulk superconductors containing high-T/sub K/ Kondo impurities and in proximity effect sandwiches containing the Kondo impurities in the normal layer are obtained using the Matsuura, Ichinose, and Nagaoka approach to treat the scattering by the Kondo impurities. The attenuation coefficients are obtained for temperatures close to T/sub c/ by suitably renormalizing th propagators and vertices appearing in the leading graphs in the expansion of te density--density correlation function appearing in the definition of the longitudinal attenuation coefficient for the case ql>>1. Closed-form expressions for the attenuation coefficient for the bulk superconductor case are obtained.
