## Abstract A plane wave is scattered by an acoustically soft or hard sphere, covered by a penetrable non‐concentric spherical lossless shell that disturbs the propagation of the incident wave field. The dimensions of the coated sphere are much smaller than the wavelength of the incident field. Low
The ergodic-theoretical formalism of nonunitary "A" transformations is compared with the derivation of kinetic equations by the hydrodynamic scaling limit. The one-dimensional hard-point system is used as an illustration. Both methods rest on the K-mixing property of the physical systems considered
