Abstract: A method and an apparatus for reproducing a virtual sound of two channels based on individual auditory characteristic are provided to set one of imaginary surround filters as a user filter based on the imaginary sound signals generated from a stereophonic sound generating part in order to generate the optimal stereophonic sound without an additional speaker. An apparatus for reproducing a virtual sound of two channels based on individual auditory characteristic comprises a hearing feature correction part(400), and a stereophonic sound generating part(410). The hearing feature correction part generates stereophonic sounds, using a plurality of imaginary surround filters. The stereophonic sound generating part generates multi-channel signals into stereophonic sound based on filter values of the imaginary surround filters. The hearing feature correction part has a test signal generating part(420), a stereophonic sound generating part(430), and a filter selection part(440). The filter selection part sets one of the imaginary surround filters as a user filter based on the imaginary sound signals generated from the stereophonic sound generating part.
