Systems and methods for automatically adjusting volume in a vehicle are provided. One method includes generating a noise prediction based on images received from a vehicle camera; determining a cabin noise level based on the noise prediction and an audio signal detected by a cabin microphone; and selectively amplifying a quiet passage within the detected audio signal to above the cabin noise level while maintaining volume level of remaining passages within the detected signal. A vehicle system includes a cabin microphone for detecting an audio signal; a camera for capturing images; and a processor configured to: generate a noise prediction based on the images; determine a cabin noise level based on the noise prediction and the detected audio signal; and selectively amplify a quiet passage within the detected signal to above the cabin noise level while maintaining volume level of remaining passages within the detected signal.

A system capable of self-adjusting both sound level and spectral content to improve audibility and intelligibility of medical device audible cues. Audible cues are stored as sound files. Ambient noise is detected, and the output of the audible cues is altered based on the ambient noise, Various embodiments include processed sound files that are more robust in noisy environments.
