Abstract
A vehicle sound generation apparatus 20 is constituted by a first pressure sensor 21a, a second pressure sensor 21b, a signal processing section 24 which performs processing of changing pressure signals output from the first pressure sensor 21a and the second pressure sensor 21b in accordance with the operation state of an automobile 10, and speakers 28a, 28b which output, as an intake sound of an engine 12, a sound pressure signal processed by the signal processing section 24. The first pressure sensor 21a is provided on an intake duct 15 connecting an air cleaner 16 and a throttle body 17 at a position between the air cleaner 16 and the center of the intake duct 15, and the second pressure sensor 21b is provided between the engine 12 and the throttle body 17.
