The objective of this thesis are to develop a parametric array system based in ultrasonic transducers, study and propose methods of preprocessing to improve on the fidelity of the audio, as compared to those in the prior art, and to propose ways to incorporate psychoacoustics effects to further improve the performance of the system. Issues such as system bandwidth and distortion measurement will be examined in this thesis.Master of Engineerin
