Abstract The possible approaches to the description of nonlinear processes caused by gas bubbles contained in liquid. Fluctuations single gas bubble in the scattering of acoustic waves in the fluid are considered as oscillating vibration. The general expressions for the pressures respectively in both the first and the n-th harmonics in an analytical form. Select the expression to assess the contribution to the practical results and the relation between the contributions of different harmonics of the signal scattered by the acoustic field.
