FIELD: radio, communication.
SUBSTANCE: method comprises applying voltage to the signal emitter, representing the sum of the traditional voltage signal proportional to the value of the desired acoustic pressure and the additional voltage signal obtained by the formula Ud(t)=k·(a0·p(t)'+a1·p(t)''), where p(t) is the acoustic pressure, which is necessary to create, p(t)', p(t)'' is the first and the second derivative of pressure in time, k is the coefficient that determines the volume level, a0, a1 are the constants in the formula, having the values at which the rate of increase and decrease of signals of acoustic pressure when creating by the electroacoustic emitter of test signals is as close as possible to the rate of increase and decrease of test signals, and the waveforms of acoustic pressure has the least distortions.
EFFECT: reduction in the amount of signal distortion.
