Patent ID: 8885843

Claim:
A sound generator that generates synthesized vehicle sound that is obtained by synthesizing vehicle sound produced from a vehicle when a specific existent component mounted on the vehicle is replaced with a new component, comprising: existent sound acquisition means that acquires sound pressure data of vehicle sound produced from the vehicle; existent component-based sound calculation means that calculates existent component-based sound caused by the existent component; existent component-based sound cancel means that calculates existent component canceled sound obtained by canceling the existent component-based sound from the sound pressure data of vehicle sound; new component-based sound calculation means that calculates new component-based sound caused by the new component; synthesized sound generation means that synthesizes the existent component canceled sound and the new component-based sound to generate a sound pressure waveform of the synthesized vehicle sound; and synthesized sound production means that produces synthesized vehicle sound based on the sound pressure waveform of the synthesized vehicle sound generated by the synthesized sound generation means.
