<P>PROBLEM TO BE SOLVED: To provide an engine sound processing device capable of effecting acceleration feeling fitted to an operation state by processing a collected engine sound to an engine sound having a reverberation effect fitted to the operation state. <P>SOLUTION: The engine sound processing device is provided having a signal processing means for dividing a received engine sound signal to two flows, the reverberation effect of a long reverberation time as a vehicle speed is high is given to the one flow and mixing it with the other flow by set mixing balance to output it; a mixing balance setting means for setting the mixing balance that a ratio of the engine sound signal given with the reverberation effect is large as the number of revolution of the engine is large to the signal processing means when both a time slope of acceleration opening and a time slope of the number of revolutions of the engine are positive, and setting the mixing balance that the ratio of the engine sound signal given with the reverberation effect is 0 to the signal processing means in the other case; and a speaker for outputting an output signal of the signal processing means as a sound. <P>COPYRIGHT: (C)2009,JPO&INPIT |
