Visual and auditory dynamic range mapping

Does anyone know of any research, white papers, draft proposals, or other
work regarding defining accessibility standards to assist users with
hypersensitive vision and hearing as is common with migraine?

I basically envision it as user settings for something like the maximum
tolerable luminance and sound volume level. Add minimum thresholds of
perception and you've got a user-defined range for the auditory and visual
content to be mapped into.

This would also benefit users who don't suffer such perception issues. For
example, gone would be the days of cranking the volume way up so you can
hear a song that's mastered at a very soft level, then getting blasted with
painfully loud sound when the next song starts (possibly even contributing
to hearing damage). The volume adjustments would be made for you
automatically. The original media would not be limited, just the
presentation of it, and the full range of the content would still be
available under user control.

This concept could be extended to compensate for other factors that can be
problematic for some users, such as contrast, color deficiency, playback
speed (audio, video, text-to-voce, animation, visual & auditory cues, etc.).

Certainly, there are many details to sort out and specify.

Reactions? Thoughts? Opinions? References? Resources? Interest?
