FIELD: technologies for emitting intensive sound waves, technology for transferring sound energy over large distances, possible use in active location equipment - long range hydro-locators, underwater communication systems, hydro-acoustic detection and control systems.
SUBSTANCE: method for suppressing nonlinear sound absorption includes, in the same direction as signal wave movement and together with wave, study of additional wave, frequency f2, phase φ2 and amplitude A2 of which is selected in accordance to following relations: f2=3f1, φ2=3φ1, A2=A1/4, where f1 - frequency, φ1 - phase, A1 - signal wave amplitude.
EFFECT: increased manufacturability of method for suppressing nonlinear sound absorption.
