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.

Apparatus and method for sound processing in a virtual reality system

A method of conducting a hearing test, and a device to perform the method, the method including configuring multiple test sound sets including multiple sound sources at each included audio frequency, wherein the sound sources, when sequentially arranged according to volume, have a uniform volume difference and a same frequency band, the uniform volume difference indicating a volume difference between neighboring sound sources, outputting the sound sources included in one of the multiple test sound sets, and determining and outputting a following test sound set according to a subject's input sound sources' number one or more times, and determining an auditory threshold of the subject regarding the audio frequency of the output test sound sets based on a result of the subject's input.
