The spectrum of rain noise shows a peak at 13.5 - 15kHz, stronger winds smear the peak. The spectral level (SL) at 15 kHz shows a linear dependence on the log of the rain rate with wind speed as a parameter. The presence of a monomolecular film on the sea surface results in a pronounced reduction of SL beneath the film by 10 log K. The damping ratio K is related to the viscoelastic properties, surface activity, concentration and diffusional coefficient of the surface-active substances composing the film.
