GAME SOUND OUTPUT DEVICE, GAME SOUND CONTROL METHOD, INFORMATION RECORDING MEDIUM, AND PROGRAM

摘要

A first sound volume calculation unit (251) obtains a length of a straight line connecting a sound emitting object and a sound detection object, and calculates a first sound volume attenuated from a predetermined reference sound volume in accordance with the length. A second volume calculation unit (252), in a case where on the straight line there is an other object that is an obstacle, calculates a second sound volume attenuated from the first sound volume by a predetermined ratio. A third volume calculation unit (253) draws from each of the sound emitting object and the sound detection object a plurality of space recognition lines that spread in plane and at a predetermined angle from the straight line locating as a center, and calculates a third sound volume attenuated from either one of the first sound volume and the second sound volume in accordance with an attenuation ratio determined by the number of the space recognition lines having a same angle and intersecting with each other without being intercepted by the other object that is an obstacle. An output sound control unit (207) outputs game sound based on the calculated third sound volume.
