Posted on July 31st, 2008 by mersenne_twister

A set of giant posters located in Madrid, London, Berlin, Brussels & Milan that monitor the noise level on a high-traffic roads. ambient noise levels are displayed via decibel meters connected to LED screens embedded in billboards.
“Local school kids are taking it a step further and are deliberately shouting at the sign in unison in order to make the numbers change. The Manager of the night club is finding the poster helpful too – he is taking photos of the sign in the early hours of the morning to show the local council that he is not making too much noise.”
