Automatic sound level

 Audio output automatically increases as external ambient sound increases

Audio monitoring of ambient noise level and automatically increase audio output to compensate. For some of us hearing impaired, to listen to radio, etc., while driving we must increase db such that when stopped at a signal it becomes deafening (is this a conundrum?). If the radio would automatically adjust downward, then back up when driving noise is increased again. Certainly there could be some threshold level to prevent breaking windows, drivers glasses, etc.

       Cars that increase the radio volume as vehicle increases speed or converts (if its a convertable) are very baked.

       My mother's Maxima did that in 1985.
