Abstract
Hypersonic attenuation in germanium at different temperatures is calculated and compared with the recent low-temperature measurements by Truell and his associates. The excellent agreement between the theory and experiment for the temperature dependence shows that Umklapp processes are responsible for the attenuation at low temperatures.
