Abstract:
1. A non-transitory computer readable storage medium having stored therein a sound-volume prediction program for a sound-volume prediction apparatus that predicts a volume of sound generated by a sound source inside an electronic device, the sound-volume prediction program causing the sound-volume prediction apparatus to execute a process comprising: extending, by using model information on the electronic device and positional information on an air-intake section and/or an air-exhaust section of the electronic device, a sound ray that indicates a transmission route of sound generated by the sound source toward the air-intake section and/or the air-exhaust section from a position of the sound source until the sound ray reaches outside of the electronic device; determining a length and a shape of the extended sound ray and a cross-sectional area and a filling rate of a flow path of the sound ray so as to predict a sound transmission characteristic; and predicting a sound transmission characteristic by using geometric information on a flow path of the extended sound ray.
