The aim of the paper is theoretical analysis of acoustic waves propagation in medium which are not homogeneous. The paper presents mathematical model and some results of numerical investigations. The mathematical model was built on the basis of the KZK equation. To solve the problem numerically the finite-difference method was applied. The on-axis pressure and power spectrum density were analysed both in homogeneous and non-homogeneous medium
