FWH Total Suraface Term

What does exactly the function Total Surface Term for FWH mean? what is its unit (kg/m^3-s^2) ? I followed the tutorial for this section and instead of two point, I have created several point in with different distances from the body. Does this mean that the pressure fluctuations per surface that create noise deliver that amount of noise to those points? because in every scenes I have different values.

The total surface term is the sum of the monopole and dipole noise that results from the surface. Pressure fluctuations are only apparent in dipole noise; the monopole noise just results from fluid being displaced by a moving body.
