This book was released on 1962 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cavity resonators with acoustically soft side walls were developed for measuring sound attenuation in sea water. The equipment is capable of such measurement at discrete frequencies between 5 and 8 kc/s, in the range from 10 to 200 db/kyd. Natural sea water with suspended particulate matter and high oxygen content showed attenuations in the whole range, in contrast to either distilled or clean sea water which produced no measurable attenuation. It is suggested that fine invisible bubbles or bubble nuclei may account for the excess attenuation. Theory and experimental results are discussed fully. (Author).

This book was released on 1980 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attempt has been made to trace the contributions of various physical and chemical factors which effect the low frequency attenuation of sound observed in deep ocean channels and to establish that chemical relaxational processes do in fact contribute to the overall attenuation of this sound. The available evidence indicates that below 0.5 kHz, attenuation is affected predominantly by diffraction and diffusive scattering, but in the range 0.5 to 2.5 kHz, it is the effects of chemical relaxation processes, involving boric acid/borate and magnesium/carbonate equilibria, which dominate the sound absorption phenomenon.
