Руденко О.В., Чиркин А.С. «Теория нелинейного взаимодействия монохроматических и шумовых волн в слабодиспергирующих средах» Журнал экспериментальной и теоретической физики, 67, № 5, с. 1903-1911 (1974)

The problem of the interaction between monochromatic and noise waves in nondispersive media is solved. The results are applied to explain a number of phenomena, e.g., the cavitation spectrum, Fermi acceleration, and sound attenuation. General formulas are obtained for transforming the spectra of the interacting waves. The interaction between the sound waves and the noise, which consists of thermal elastic waves of the meidum, are considered in detail. The theory of sound attenuation developed in the paper takes into account effects due to the finite sound amplitude, the presence of external noise, etc. Under certain conditins, these effects lead, in particular, to the Landau-Rumer formula for the absorption coefficient in solids. Application of the theory to liquids and gases yields an estimate of the sound absorption due to the translational motion of the molecules with allowance for fluctuations in the media
