RT60 = k(V/Sa)

  • k is a constant that equals 0.161 when the units of measurement are expressed in meters and 0.049 when units are expressed in feet.
  • Sa is the total surface absorption of a room expressed in sabins. It is a sum of all the surface areas in the room multiplied by their respective absorption coefficients. The absorption coefficients express the absorption factor of materials at given frequencies.
  • V is the volume of the room
