FIELD: metrology.
SUBSTANCE: invention relates to metrology, specifically to methods for detecting hydroacoustic noise emission. Method for detecting hydroacoustic actions comprises arranging hydroacoustic receiving hydrophone module in natural water body on anchor with a float, measurement of receiving module of parameters of a noisy object during further processing of such parameters on computer. Receiving hydrophone module is represented by high-sensitive sensor of angular speed. Angular speed is measured, obtained information is processed in a computing unit and based on determined value characterising measured hydroacoustic action by mathematical expression: 
where t is time for measurement; L is radius of rotation of sensor; 
EFFECT: technical result is wider of range of detection of hydro-acoustic effects in low-frequency region.
