A smart ringer

serendipitous altruism has dug up a patent for a telephone that adapts the telephone ring volume to the level of ambient noise - beyond manually adjusting the volume level or setting on "silent" mode.

"A telephone monitors ambient noise, and alters the characteristics of the audible ring to distinguish the sound of the ringing telephone from the ambient noise. Such characteristics include the decibel level, the sound frequency, and the rhythmic pattern or the ringing sound”.
