Abstract: An overlap identifying unit (205) obtains respective directions of the sound emitting objects with respect to the hearing position and identifies each one of sound emitting objects whose directions overlap. A sound volume estimation unit (206) estimates respective sound volumes of sounds as heard at the hearing position, emitted from the sound emitting objects that the overlap identification unit identified as overlapping. A sound emission control unit (207) cancels the sound emission of either one of the identified sound emitting objects identified, in a case where a difference between sound volumes obtained from those respective sound volumes estimated by the sound volume estimation unit (206) is at a predetermined level or greater. A sound source (208) reproduces sound effects or the like of the predetermined volumes. A game sound output unit (209) suitably outputs the game sound reproduced from the sound source (208).

Abstract: A game program KGP for playing a game by operating a keyboard connected with a computer in response to a picture displayed on a monitor 9 has a procedure for detecting and computing number of keys (S2 through S9), for detecting and computing number of keys of the keyboard 17 connected with a game machine body, and a procedure for setting key set (S9 through S13), for setting one or more key sets on the keyboard according to the number of keys if the detected number of keys is a predetermined number of keys or more. Then, people can easily enjoy the keyboard game program with only a general purpose keyboard, and it is not necessary to specifically prepare a dedicated controller, thereby providing the game program usable for various purposes.
