Giant Billboards Visualize Noise Pollution

A set of billboards in four European cities measure the local area’s noise pollution level and display it live for passerby’s to see. It’s an advertisement for AEG-Electrolux’s quiet running washing machines, but also a simple public service. Quantifying an abstract figure such as noise pollution could help people become more aware of the problem. Besides getting immediate feedback on noise pollution, the data is sent to a website where you can compare noise levels from city to city.
