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 risk degree determining unit that is capable of determining a risk degree of the vehicle based on the running state detected by the running state detecting unit, and a sound effect generation unit that, when the risk degree determining unit determines a risk degree which is a predetermined value or more, synthesizes the fundamental wave sound with one or more discordant adjustment wave sounds having a discordant frequency component other than an integer-order frequency component and a half-order frequency component.

Claim (Index 1):
A vehicle sound effect generation apparatus for generating 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 comprising:\n a running state detecting unit that detects a running state of a vehicle; a risk degree determining unit that is capable of determining a risk degree of the vehicle based on the running state detected by the running state detecting unit; and a sound effect generation unit that, when the risk degree determining unit determines a risk degree which is a predetermined value or more, synthesizes the fundamental wave sound with one or more discordant adjustment wave sounds having a discordant frequency component other than an integer-order frequency component and a half-order frequency component.
