Parametric array loudspeaker (PAL) can achieve a sharp directivity utilizing the straightness of ultrasounds. A carrier wave in the ultrasonic range is modulated with target sound and emitted intensely. Then the target sound is self-demodulated du...

High presence sound field reproduction technology has recently gained attention. We have previously proposed a virtual sound source (VSS) construction method based on wave field synthesis (WFS) using parametric loudspeaker array (PAL array). The p...
3-D sound field reproduction systems can provide a high presence. These systems commonly use electro-dynamic loudspeakers. Electro-dynamic loudspeakers tend to construct diffuse sound images due to its wide directivity and high reverberation. In c...
