Intermediate Frequency Sound Absorption in Seawater: The Role of Magnesium Sulphate,
MATERIALS RESEARCH LABS ASCOT VALE (AUSTRALIA)
Pagination or Media Count:
The resonant absorption frequency, and the excess absorption parameter for 0.014 m MgSO4 in water a 4 C and 100 atmosphere pressure have been calculated and agree quite closely with those values defined by the Thorp equation for deep ocean sound channel absorption at intermediate frequencies.
