N2 - In this paper, distortion analysis and reduction for the parametric array loudspeaker is being presented. The parametric loudspeaker has been found useful in generating a highly directional sound beam. However, due to the nonlinear interaction of ultrasonic wave in air, several undesired harmonic distortions have been generated. Conventional approaches in reducing the distortion have not created satisfying solutions. A new approach capable of further reducing the distortion has been proposed in this paper. Several simulation results are being carried out in this work to test and compare the effectiveness of this proposed solution with conventional approaches.
