#866: AmpliPhone

I have a friend who tends to shout into her phone…my hearing is not too acute and yet I can listen to her clearly with the phone held 0.5m from my ear.

Today’s invention is a software function built into phones which allows the volume setting to be adjusted according to the incoming number.

Once the volume is manually adjusted, the first time each person calls, this optimal listening level is stored with their number so that quiet speakers are boosted automatically (and vice versa).
