摘要：

Multizone　soundfield　reproduction　with　various　potential　applications　has　recently　been　drawn　more　and　more　attention　in　acoustic　signal　processing.　However,　the　literatures　related　to　multizone　soundfield　reproduction　are　mainly　limited　to　2D　multizone　scenarios.　In　this　paper,　based　on　spherical　harmonic　analysis,　we　seek　to　recreate　a　3D　multizone　soundfield　using　a　single　spherical　loudspeaker　array.　The　desired　local　soundfield　coefficients　are　mapped　into　the　equivalent　global　soundfield　coefficients　using　spherical　addition　theorem　for　Bessel　function.　The　mode　matching　approach　is　used　to　derive　loudspeaker　weights　in　the　reproduction　step.　The　experiments　show　that　the　proposed　method　can　reproduce　the　target　3D　spatial　multizone　soundfield　accurately.　©　2015　IEEE.
