Claim Text:
1. A vehicle system, comprising: a sound augmentation system comprising a sound augmentation generator coupled to at least one audio output, the sound augmentation generator produces an augmented audio output to drive the at least one audio output based on a transfer function and a plurality of audio tuning parameters; and a sound augmentation system health monitor coupled to at least one input and a feedback of the augmented audio output, the sound augmentation system health monitor compares the feedback of the augmented audio output to a level of the at least one input relative to at least one environmental condition to determine a current performance level of the sound augmentation system, determines a difference between the current performance level of the sound augmentation system and at least one performance threshold level, and initiates an alert upon determining that the difference is at a predetermined level, wherein the sound augmentation system health monitor develops a plurality of boundary maps based on the level of the at least one input relative to the at least one environmental condition and a plurality of thresholds, and the plurality of boundary maps are combined with a generalized sound augmentation system-on map defining expected normal levels of performance relative to the at least one environmental condition when the sound augmentation system is active and a generalized sound augmentation system-off map defining expected normal levels of performance relative to the at least one environmental condition when the sound augmentation system is inactive, and further wherein the boundary maps are defined at levels between the generalized sound augmentation system-on map and the generalized sound augmentation system-off map.
