Android :: Volume Controls For Adjusting Notification Sounds Automatically?

An app or mod that will use the microphone to sense the amount of noise around you and adjust the notifications accordingly - that is to say when its quiet, next to my bed and I am sleeping I want it to be all quiet sounds - but when I am working and there is fan noises and other stuff that is louder then normal I want the notifications to be loud - but if I walk into the break room which is quiet I want it to be quiet again - or if I am listening to music in a room or car turn up the notifications so I can here them and back down when not. You know take a sound reading and turn up or down the volume of the notification that is happening at that given time.

Only problem being when its in your pocket it will always seem to be quieter then normal so they will be quiet also, so there would need to be something to listen to the sound and determine if its being muffled by a pocket or whatever and turn it up then - if playing a sound and analysing that sound it should be able to determine what environment the phone is in, like a pocket or bag that will make it quieter. I am not even sure if i am describing this properly but I know someone can probably figure it out, but it might have to be something the manufacturer does, like that phone that has 2 microphones to auto cancel out background noises like a bluetooth headset.
