Abstract. The aim of the study is to adapt the method of impedance spectroscopy as applied to the assessment of possible effects of acoustic impact of various parameters.

Materials and research methods. The study was carried out using 70 rabbits (chinchilla) weighing 2.5-3 kg. Five experimental and control groups were formed based on a preliminary examination of the animals in order to cull individuals with altered acoustic stem evoked potential and other parameters. The experimental animals were exposed to five series of 160 acoustic pulses with low-frequency spectrum each.

Results of the study and their analysis. The study showed the promising prospects of using the method of impedansometry in experimental work to assess the impact of acoustic factors on the functional state of the body.

High sensitivity of the method was also proved, allowing to identify difference in the negative impact of acoustic factors of different parameters, which were not identified, in particular, in the analysis of the altered acoustic stem evoked potential.

The results of this work confirmed the need for further research on this phenomenon and for the search for methods of assessing the functional state at the organ and organism levels, correlating with impedance parameters.

Keywords: acoustic stem evoked potential, effects, impedance polarization, impedance spectrometry, intensity, lung biophysical parameters, non-lethal weapon systems, parametric emitter, parametric exposure, peak level, phase angle, probabilistic and temporal characteristics, shock-acoustic effect
