    "abstract": "The system of hydrodynamic-type equations, derived by two-side distribution\nfunction for a stratified gas in gravity field is applied to a problem of\nultrasound propagation and attenuation. The background state and linearized\nversion of the obtained system is studied and compared with the Navier-Stokes\none at arbitrary Knudsen numbers. The WKB solutions for ultrasound in a\nstratified medium are constructed in explicit form. The problem of a generation\nby a moving plane in a rarefied gas is explored and used as a test while\ncompared with experiment.",
