The method for the absolute values of preliminary computed acoustic parameters oscillations, transmitted in axisymmetrical channels is proposed. The equation for the second order acoustic potential and condition of solvability of this equation are used. The formula for the stream of acoustic energy for the second order values is obtained. Examples of acoustic parameters amplitude dependence on the acoustic admittance of fuel on the channel's walls are considered.
