Revision history [back]

How often have meetings been disturbed by phones ringing with max. volume? How often did you miss a call when outside and the volume was not adjusted to max.? An ascending alert tone could be one solution, but there might be missed calls if the ascending goes too slow. A quicker solution could be to listen to the noise level upon an incoming alert and decide about the ringer volume. The only danger I see is if the phone is not close to you. E.g. at home the phone lies in another room and rings with low volume because its quiet there. Anyway, the phone should know when it's home, based on WLAN, GPS, or cell IDs. This home status could be used by various apps, e.g. to relax security requirements like unlock code or lock timeout. In this example, the ringing volume could be fixed to a pre-determined volume because we know the environment.

Ring tone volume should adapt to surrounding noise level, also considering that it the phone could be stored in a case.
