Except that such a phone would go quiet when I climb on the roof of a building (a GPS not necessarily detecting my elevation), I like the idea. On the other hand, perhaps if I'm climbing on the roof of a building, quiet mode is warranted... |

//Could this instead be done through direct measurement of ambient noise levels when the user isn't speaking?// |

Shhhhhhhhh! Is that someone's phone? <silence abounds in large clods> ... <Ringing gets quieter> ... Okay, make a noise, I can't hear the phone else. |

[danielo]GPS can be used in two ways: either detect your position or, if you _can't_ detect your position, assume that you're in a building. Once on the roof, the satellites become visible again => you're outside. |

[boysparks]This is for both speaker and ringer volumes, and perhaps the microphone sensitivity as well -- by switching "profiles" you actually change all those settings at once. Measuring noise can serve as a backup method, but it has its own problems: e.g. the user may block the noise-measuring microphone. |
