<p>PROBLEM TO BE SOLVED: To reduce workload related to arrangement of an acoustic shielding object in a complex shape in a virtual space.SOLUTION: A video game processing device 100 includes: an acoustic management table for managing sound to be listened at a listening position as acoustic information outputted by a voice output part 14; and a shielding object management table for managing shielding object information that includes a shield factor showing a rate at which a shielding object representing a virtual object that shields sound in a virtual space, among virtual objects present in the virtual space, shields sound in the virtual space and a position of the shielding object arranged in the virtual space. The sound to be listened is derived on the basis of a sound source position, the listening position, and the shielding object information in the virtual space, and acoustic information is updated according to the derivation of the sound to be listened. The shielding object includes a joint shielding plate-shaped object comprising a joint shield plate formed by joining a plurality of polygonal basic shielding plates.</p> |
