Abstract
This work devoted to research the temperature and salinity distribution in ocean turbulence. The sound velocity when ocean turbulence presented was calculated by the function relation between temperature, salinity, depth and sound velocity. The sound transmission loss was calculated when the ocean turbulence was presented or not and compared them. The sound field fluctuation resulted by ocean turbulence was analyzed. It was very significant to comprehend the mechanism and variation rule of ocean turbulence. Thus it was further study the effect of ocean turbulence on acoustic propagation. As an example, there was thermocline in the ocean water. The sound transmission loss was calculated when presented ocean turbulence or not. It analyzed the effect of ocean turbulence on acoustic propagation. The sound field fluctuation caused by ocean turbulence could reach 8dB.
