Noise management: Sound and vision

Computer simulations that paint Europe's cities in riotous colour are at the core of a bold plan to restore peace and quiet to a population driven to distraction by traffic noise. Declan Butler takes a tour.

I'm swooping down the boulevards of Paris in a virtual simulation of the city of light, where sound levels are depicted as colour. The deep blue roar of traffic washes along the streets, blazing crimson against the base of adjacent buildings, fading to orange and gold further up the façades where the noise is fainter.
