Abstract:
1. A pseudo sound generation device mounted to a vehicle that is equipped with a drive mechanism, comprising: an acquisition part that acquires traveling information reflecting the operational state of said drive mechanism; a derivation part that derives pseudo sound-related information on the basis of said acquired traveling information, including rotating speed information of said drive mechanism, which is corresponding to engine rotating speed when said drive mechanism is an engine; a generation part that generates a pseudo sound signal having a waveform corresponding to said derived pseudo sound-related information; a control part that performs a reduction designation to reduce the level of said pseudo sound signal at a first time rate of change, when said operational state is a constant rotating speed state, in which said rotating speed information included in said derived pseudo sound-related information is changed within a predetermined range, continued over a predetermined time period after said constant rotating speed state begins; an adjustment part that adjusts the level of said pseudo sound signal according to a designation from said control part; and a speaker that outputs pseudo sound according to the pseudo sound signal of which level has been adjusted by said adjustment part.
