Whenever steam escapes in the atmosphere it creates lot of sound but when high pressure air escapes it does not produce that high sound level . Why ?

The sound speed of a two-phase fluid, such as a magma-gas, water-air, or water-steam mixture, is dramatically different from the sound speed of either pure component.
The sound speeds of the pure liquid and gas are nearly independent of pressure, but the sound speed of a mixture is highly dependent on pressure and temperature (difference of pressure at the exit of a pipe). The sound speed in a single-component two-phase system, such as a water-steam mixture, depends on whether or not equilibrium between the phases on the saturation curve is maintained. Heat and mass transfer which occur when equilibrium is maintained and cause the sound speed to be much lower than under non-equilibrium conditions in which heat and mass transfer are absent.
