Abstract
A vehicle sound effect generation apparatus generates a sound effect of an engine based on a vibration sound database including a fundamental wave sound having a fundamental frequency component and a plurality of adjustment wave sounds having a frequency component other than the fundamental frequency component. The vehicle sound effect generation apparatus includes a running state detecting unit that detects a running state of a vehicle, a sound effect generation unit that synthesizes the fundamental wave sound with the adjustment wave sounds based on the running state of the vehicle, and a visual guidance direction setting unit that sets a visual guidance direction at which a vehicle occupant shoots a look. The sound effect generation unit causes output characteristics of a sound effect in the visual guidance direction to increase more than output characteristics of a sound effect in a direction other than the visual guidance direction.
