WebThe speed of sound (a) is equal to the square root of the ratio of specific heats (g) times the gas constant (R) times the absolute temperature (T). a = sqrt [g * R * T] The derivation of this equation is given on a separate page. Notice that the temperature must be specified on an absolute scale (Kelvin or Rankine). WebThe energy (as kinetic energy 1 2 m v 2 1 2 m v 2) of an oscillating element of air due to a traveling sound wave is proportional to its amplitude squared. In this equation, ρ ρ is the density of the material in which the sound wave travels, in units of kg/m 3, kg/m 3, and v is the speed of sound in the medium
