US Patent 10068620 Affective sound augmentation for automotive applications

In order to affect the mood of a vehicle operator (for example, to increase attentiveness), embodiments of the invention automatically sequence appropriate audio cues into the sound playback from a vehicle's sound system. These cues represent events related to the vehicle or taking place in the vicinity of the vehicle, and can be modulated or effected so as to better convey the vehicle event. These cues may also be part of a coherent soundscape representing a fantasy scenario, such as motocross, sailing, or stand-up paddle boarding. Both the soundscape and the mapping of vehicle events to sound cues are configurable by the user.
