«Acoustic pollution» is a dangerous anthropogenic load on the ecosystems of the World Ocean. At present, hydroacoustic emitters are widely used to solve a variety of scientific and applied problems, no longer limited to the traditional tasks of long-distance sound underwater communications, remote control, illumination of the underwater environment, acoustic thermometry of the ocean climate, monitoring of underwater objects, geological, seismic and fishery exploration. In many of the above mentioned applications, in particular in the tasks of providing long-distance sound underwater communication as well as in conducting geological and seismic exploration, powerful sources of low-frequency hydroacoustic fields are needed. The sound pressure created by such hydroacoustic emitters reaches several thousand, and in some cases — tens of thousands of Pa (reduced to 1 m). The effect of sound fields of such intensity on aquatic organisms has hardly been studied. The main problem of such studies is the difficulty in recording the impact of powerful acoustic fields on marine ecosystems. This work is devoted to the development of a methodology for researching the influence of powerful low-frequency sound fields on luminous planktonic marine organisms. The methodology is based on determining the parameters of bioluminescence, which is one of the most important indicators of the functional state of aquatic organisms.
