Abstract
Proceeding from the concepts of localization processes in anharmonic l attices with impurity quasi-local excitations (resonance localized sca ttering centers) universal anomalies in the temperature dependences of the reciprocal length of ultrasound attenuation in amorphous systems are described within the temperature range where a plateau in thermal conductivity is observable. A probability of the manifestation of the localization process in quantum crystals is also discussed.
