AB  - Human auditory does not perceive sound of all frequencies with equal loudness. It is known that a low frequency signal needs to be produced with higher power level to have the same loudness as the middle frequency part. There are two ways to overcome this problem. There are either carried out by boosting the power of the low frequency part or utilizing psychoacoustics' effect called the 'missing fundamental'. Parametric array's usage to generate highly directional audible signal has been reported since few decades ago. However the reproduced signal lacks low frequency content. One reason is the relatively low power level produced by the existing parametric array. Utilizing the non-linearity of air, it is proposed to psycho-acoustically enhance the low frequency perception of a parametric array loudspeaker.
