The dynamics of weak harmonic disturbances in a superheated water-air bubble medium is studied when in addition to water vapor there is an inert gas (e.g. air) that does not participate in phase transitions. The maps of the stability zones of the considered systems are analyzed depending on the value of the liquid overheating on the “volume content - bubble radius” plane with an increase in the equilibrium pressure from 0.1 to 10 MPa. The effect of the initial pressure amplitude and the overheating (from hundredths to one degree) on the dispersion of harmonic waves as well as the dependence of the increment on the bubble radius for unstable systems are investigated.
