AEG wanted to promote the fact that its new washing-machine models were virtually silent. Its solution was to highlight the issue of noise in five European cities.
Large-format outdoor sites were installed at busy road crossings complete with LED decibel monitors in Berlin, Brussels, London, Madrid and Milan.
The screens displayed live decibel readings updated every two to three seconds, 24 hours a day, and contrasted perfectly with AEG's tagline: "In a noisy world, appliances that aren't."
The readings from the decibel monitors could also be viewed online at a special website.
