The behaviour of acoustic waves in nonlinear medium is well established in literature. But there is a need of a simple computational tool through which practical problems pertaining to nonlinear acoustics can be treated with minimum effort and expense. Additionally, visualization of nonlinear acoustic waves can be useful towards the applications of acoustic diodes and ultrasonic waves. To address this issue, we have developed a numerical scheme which effectively captures the self-distortion mechanism of acoustic wave in nonlinear medium and the consequential generation of higher harmonics. Additionally, the effects of increasing non-linearity constant of the medium and amplitude of sound waves on distortion of the waveform is studied.
