It is demonstrated that the universally accepted system of gas-dynamic hydrodynamic equations is applicable only to homogeneous isentropic media and requires advancement to get applicable to non-homogeneous media. A generalized equation of gravitational wave for adiabatic and ideal media is obtained from advanced system. From this equation, in turn, is obtained an equation of acoustic wave, which is plane and different form the known equation in that the phase speed of the wave in the Earth atmosphere obviously depends on altitude, i.e. C = C z, T instead of accepted C = C T. Thus, acoustic wave is a short-period gravitational wave in which gravitational effects are revealed at altitudes z > 2.3 × 103 m, which leads to amplification of refraction of sound. The sphere of applicability of the equation is determined and it is demonstrated that it is true only up to the upper boundary of the troposphere z ≤ 11 - 12km. above which anomalous processes develop in the atmosphere.
