The theory of squeeze film pressure and the theory of acoustic radiation pressure have been generalized to a new theory in this study. When the two flat faces are separated by a compressible fluid film, a dynamic pressure is generated in their normal direction by the oscillation of the faces. In this paper, an analytical solution to the differential equation for the phenomenon considering both the inertia and the viscosity of the fluid is presented. The relationship between the squeeze film pressure and Langevin radiation pressure is also investigated theoretically. The results show that the inertia efects of the fluid on the pressure reveal when a Reynolds number is larger then 1. If a Reynolds number is small enough to neglect the inertia effects, the conventional lubrication theory can be applied to the phenomenon. The time average value of the pressure generated by the inertia of the fluid can be considered to be Langevin radiation pressure.
