Sound localization of stereo reproduction with parametric loudspeakers

Abstract (in Japanese) (See Japanese page) 
(in English) We can perceive sound localization in stereo reproduction using ordinary left and right loudspeakers. A parametric loudspeaker is known as a super-directivity loudspeaker and realizes a spot sound reproduction. In this report, subjective tests were conducted to clarify characteristics of sound localization of the parametric loudspeakers. Subjective test results showed that listeners perceived correct sound localization of all signals using the parametric loudspeakers. However, they could not perceive it using the ordinary loudspeakers in the case of sinusoidal waves with binaural information ITD. It was determined that the parametric loudspeaker could exclude the contradiction between the binaural information ILD and ITD that occurred in stereo reproduction with ordinary dynamic loudspeakers because the super directivity of parametric loudspeaker suppressed the cross talk components.
