Abstract
The ultrasonic attenuation in glasses at low temperatures is calculated using the model proposed by Anderson, Halperin, and Varma. It is found that the resonant absorption of sound by the localized two-level systems saturates and can be observed only if the sound amplitude is extremely small. A second contribution to the sound absorption is derived which arises from the relaxation of the localized excitations and does not saturate. Qualitative agreement with recent measurements of the ultrasonic attenuation in fused silica is obtained.

This work grew out of many stimulating discussions with Dr. S. Hunklinger. I am very indebted to him for sharing with me his knowledge of amorphous solids and keeping me informed on the process of the experimental work. I wish to thank also Dipl.-Phys. W. Arnold, P. Berberich, P. Leiderer, Professors K. Dransfeld, R. Nava, H. Wagner, and Dr. M. Papoular for helpful discussions and comments.
