Abstract
An apparatus to perform sound processing in a virtual reality system includes a sound processing unit to process and produce sound output in sound areas divided into a focus area within a predetermined visual field and a non-focus area out of the predetermined visual field in a virtual reality space for sound sources; and a control unit to divide the sound areas into the focus area and the non-focus area, and to control the sound output of the sound processing unit such that a volume of sound in a first space is gradually decreased while a volume of sound in a second space is gradually increased when a space shift from the first space to the second space in the virtual reality space is detected.
