<P>PROBLEM TO BE SOLVED: To provide a sound production device that can produce a vehicle sound with a specific sound component changed among a plurality of sound components occurring while a plurality of parts installed on a vehicle are in operation. <P>SOLUTION: A sound production device 1 comprises: current sound acquisition means 2 for acquiring sound pressure data of a vehicle sound occurring on a vehicle; current part-attributable sound calculation means 4 for calculating a current part-attributable sound occurring due to a specific part in a vehicle sound; current part-attributable sound removal means 3 for calculating a current part-removed sound in which the current part-attributable sound is removed from the vehicle sound; new part-attributable sound calculation means 5 for calculating a new part-attributable sound generated by changing the current part-attributable sound; synthetic sound production means 6 for producing a sound pressure waveform of a synthetic vehicle sound in which the new part-attributable sound is combined with the current part-removed sound; and synthetic sound generating means 7 for generating a sound based on the sound pressure waveform of the synthetic vehicle sound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
