Abstract : The paper combines previously developed theories of surface and volume scattering and reflection with published and previously unpublished acoustic reverberation data to develop a composite theory for reverberation strength as a function of acoustic frequency, incidence or grazing angle, and sea-surface wind speed. In passing, spectra of sea-surface roughness and of the surface sublayer turbulence are developed, these spectra being consonant with theoretical and experimental estimates. (Author)
