5. In the version of the ideal gas law used here, m is the mass of the gas and R is the gas constant. The gas constant is defined such that mR = nR̄, where n is the number of moles in the parcel and R̄ is the universal gas constant.
6. Because p varies nonlinearly with x in the present model, we have used the displacement amplitude to match the two models.
