摘要：

Reproduction　of　a　multi-source　sound　field　is　an　important　problem　which　should　be　considered　in　acoustic　signal　processing.　A　common　method　is　to　use　an　array　of　loudspeakers　to　reproduce　the　desired　sound　field　where　the　driving　function　is　the　key　issue.　In　this　paper,　a　multi-source　sound　field　reproduction　method　using　cylindrical　harmonic　analysis　is　proposed.　Cylindrical　harmonic　analysis　is　used　to　derive　the　loudspeaker　driving　functions.　Specifically,　this　paper　presents　an　analysis　on　the　impact　of　cylindrical　harmonic　orders　for　the　truncation　problem　in　actual　system.　The　experiments　indicate　that　the　proposed　method　can　reproduce　the　target　multi-source　sound　field　accurately　with　a　large　range　of　effective　listening　area.　©　2014　IEEE.
