Abstract

Recently, studies on reproduction of realistic sound field for communication with presence have been under-taken. In previous study, sound field reproduction using principle of boundary surface control did not consider acoustic echo. Because of acoustic echo, precision of soundfield reproduction is dropped. In this study, Modeling of acoustic tube and reflected wave rejection using the model are proposed because acoustic echo is caused by reflected wave. Validity of model was confirmed by servo analyzer and reflected wave rejection was verified by simulation.
