Abstract
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.
