I would appreciate voice rolloff curves that are based on the person's voice volume. For example, if you whisper to someone, the sound should taper off very quickly, but if you are yelling out, the sound should project much farther. This would make it easier to hold conversations in a talking voice, while also not losing the ability to get the attention of others from a distance.
A great example would be talking to your friends in a club, and then yelling something for the DJ to hear, or whispering something to your fellow murderer in a murder game so that nobody else can hear it
should be something you could turn on and off, i.e. if you were to play music, and something you can configure, so you can choose how loud you need to be in order to project your voice or whisper
