  1. (Also velocity of sound.) Usually taken to mean the phase speed of an acoustic (or sound) wave.
    In an ideal, stationary gas the speed of sound c is a thermodynamic property depending only on the equilibrium state of the gas and is given by
    ams2001glos-Se45
    where γ is the ratio of specific heat capacities, at constant pressure and volume, respectively; R is the gas constant; and T is absolute temperature.
  2. In seawater, a function of temperature, salinity, and pressure.
