摘要：
The results of experiments on the damping of a weak high-frequency pulse in the field of a strong low-frequency pump wave in a heat-treated (annealed) cooper rod resonator are reported. In order to describe the observed phenomenon, it is assumed that the logarithmic decrement of the acoustic wave depends on the strain amplitude of the wave in the metal.
