Sound image localization device

摘要

A sound image localization device ( 10 ) comprising: band division means ( 11 ) for dividing an inputted acoustic signal to a high-band acoustic signal and a low-band acoustic signal; a first filter ( 12 ) and a second filter ( 13 ) for localizing the high-band acoustic signal; low-band localization means ( 16 ) having a third filter ( 14 ) and a fourth filter ( 15 ) for localizing the low-band acoustic signal; a first adder ( 17 ) for adding the output signals of the first filter ( 12 ) and the third filter ( 14 ), and a second adder ( 18 ) for adding the output signals of the second filter ( 13 ) and the fourth filter ( 15 ). The sound image localization device ( 10 ) having such a configuration mitigates the limit of the listening position as compared to the conventional one and enables localization of the sound image in any direction around a listener.
