Abstract:
The article presents the results of studying the acoustic radiation affecting the conductivity of the seawater (a solution of salt (NaCl) in water). At a salinity of 35 g/L (‰), pressure of 500–2500 Pa (Pascal), and power flux density for acoustic vibrations within 0.5–2.5 W/m, the conversion coefficient for the electromagnetic field frequency under acoustic radiation varied from 10$^{-4}$ to 2 $\cdot$ 10$^{-2}$. At a salinity of 12 g/l (‰), the authors observed a slump for this coefficient. Compared to the effect of hydrostatic pressure on the conductivity of seawater, ultrasound is three orders of magnitude more intense. The materials of the article can be applied to the problems of maritime communications and geophysics.
