Abstract
A sound generator is provided capable of generating vehicle sound that will be produced when a specific sound element is changed out of a plurality of sound elements arising from the operation of a plurality of components mounted on a vehicle. A sound generatorincludes: existent sound acquisition meansthat acquires sound pressure data of vehicle sound produced from a vehicle; existent component-based sound calculation meansthat calculates existent component-based sound caused by an existent component out of the vehicle sound; existent component-based sound cancel meansthat calculates existent component canceled sound obtained by canceling the existent component-based sound from the vehicle sound; new component-based sound calculation meansthat calculates new component-based sound caused by changing of the existent component-based sound; synthesized sound generation meansthat synthesizes the existent component canceled sound and the new component-based sound to generate a sound pressure waveform of synthesized vehicle sound; and synthesized sound production meansthat produces sound based on the sound pressure waveform of the synthesized vehicle sound.
