The Toll

Issue

The population / demographic of Venice is declining, b/c there are more deaths than births. The current average age in Venice is around 50.

Concept

beam ultra-directional sound in a place, so that when someone walks by they can hear a toll. There would be one sound for each person who died, and a different sound for each birth that day. these would alternate, then when one count completed, the other sound would continue. These counts can be found online.

Next Step

investigate the microwave speakers.

search "supermarket directional speakers"
