This paper investigates the applicability of parametric array loudspeakers to render 3D audio. Unlike conventional loudspeakers, parametric array loudspeakers are able to produce sound in a highly directional manner, therefore reducing interaural crosstalk and room reflections. The investigation is carried out by performing objective evaluation and comparison between parametric array loudspeakers, conventional loudspeakers, and headphones. The objective evaluation includes crosstalk measurement and binaural cue analysis using a binaural hearing model. Additionally, the paper also investigates how the positioning of the parametric array loudspeakers affects 3D audio rendering.
