Abstract: A vehicle system is provided that includes a sound augmentation system with a sound augmentation generator that produces an augmented audio output to drive at least one audio output based on a transfer function. The vehicle system also includes a sound augmentation system health monitor that determines a current performance level of the sound augmentation system based on at least one audio input and a feedback of the augmented audio output, and triggers a transfer function update prompt based on a difference between the current performance level and an expected performance level being at a threshold level. A user interface outputs the transfer function update prompt and receives a transfer function calibration request in response to the transfer function update prompt. A transfer function calibration module drives a calibration sequence on at least one audio output and monitors at least one audio input to determine an updated transfer function.
