Abstract
A vehicle sound effect generation apparatus includes a running state detecting unit that detects a running state of a vehicle, an adjustment wave sound selector that selects one or more adjustment wave sounds having a half-order frequency component or an integer-order frequency component, a sound effect generation unit that synthesizes a fundamental wave sound having a fundamental frequency component with the one or more adjustment wave sounds selected by the adjustment wave sound selector, and an inhibition condition determining unit that can determine a condition that correspondence between an amount of an operation performed by a vehicle occupant and a behavior of the vehicle is inhibited. When the inhibition condition determining unit determines the condition that the correspondence between the amount of the operation and the behavior of the vehicle is inhibited, the adjustment wave sound selector reduces the output characteristics of the adjustment wave sounds selected.
