摘要:
Three‐dimensional angular distributions of acoustic scattering strength arising from flexural and Rayleigh resonances of a prolate steel spheroid are presented. Flexural resonances are found to produce strong scattering into four almost symmetrical lobes, by as much as 20 dB above the nonresonant background. Rayleigh resonances are weaker, but significant portions of the scattered Rayleigh energy are radiated into steep angles. In both cases, considerable interactions of the scattered energy with waveguide boundaries may be expected.

摘要:
This letter presents regression equations for determining sound velocity in marine sediments of the Brazil Basin (NW South Atlantic). These equations are a revision of an earlier work by Orsi and Dunn [J. Acoust. Soc. Am.88, 1536–1542 (1990)], whereinsituvelocities were used to examine selected empirical relationships. In this letter, sediment sound velocities have been corrected to standard laboratory conditions to recompute the equations, as well as several other statistical characteristics. Additional new relationships have been derived that permit calculation of velocity ratio. The relationships between properties and their statistical significance remain unchanged, and the reader is referred to the original study for detailed discussion.
