Download or read book Acoustic Reverberation at the Sea Surface: Surface and Sublayer Spectra Vis-a-Vis Scattering and Reflection written by John J. Martin and published by . This book was released on 1968 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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combines previously developed theories of surface and volume scattering and reflection with published and previously unpublished acoustic reverberation data to develop a composite theory for reverberation strength as a function of acoustic frequency, incidence or grazing angle, and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).
