Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a crosstalk reduction framework for portable parametric array loudspeakers (PALs) using the Semi-Blind Multiple-Input/Output Inverse Theorem (SBM) in conjunction with decorrelation-based adaptive inverse filtering (DAIF). The proposed method aims to realize independent binaural listening without requiring prior identification of the acoustic transfer functions between the PALs and the listener. Crosstalk resulting from the short distance between the PALs and the listener is mitigated by SBM, while DAIF provides adaptive inverse filter updates to accommodate temporal variations in the transfer characteristics. Numerical simulations confirm the effectiveness of the proposed approach in suppressing crosstalk in portable PAL environments.
