complex app request/idea

So this might be a little to intensive, but hear me out. Would there be a way to make an app so that your ringer profile changes based on the ambient noise around you. For example, i have mine set to normal which is fine in regular environments, but if i walk into like the library its retardedly loud. Or if i'm listening to music i can barely hear it on normal, but can in Loud setting. The program would basically turn on the mic for a fraction of a second before the ring comes on, measure the ambient noise, and change the ringer volume accordingly.

I think it would be sick and useful, rather than having to change the volume settings a ton of times throughout the day.

Edit: I just saw the GPS enabled request, but that would only work if you are going from outside to inside (my gps almost never works inside).

wonder if this is even possible

It would be cool if it was possible

I'm not a programmer just adding to the idea.

This would be a battery killer is my first thought.

If you programmed a decibel meter to adjust profiles it could in theory work

The phone has a mic so it should be possible. Still, there migh be some OS stuff that prevents the changing of sound profiles like that. And then, how accurate would it be? In a Holster, pocket, handbag, etc?
