What are the sounds usually associated with a city? The irritating ones issued from cars hooting, tyres screeching, trams rumbling, from air-conditioning units humming relentlessly? From ambulances swishing by with sirens amplified by the Doppler effect that hurts our eardrums and sets our minds on alert? When embarking on a trip to a busy metropolis, an undistinguishable concoction of man-made noise will have to be tolerated as an inevitable part of the package. Positive connotations are asking for more pleasant experiences, though.
Conquering an urban jungle by mapping it out via the typical sounds it exudes, is an idea temporarily put into practice in Paris, Brussels and Amsterdam during an “ambient marketing” campaign: from interactive audio billboards, the “Sounds of the City” could be tapped by means of a personal headphone plugged into jacks directly embedded in the “neighbourhoods” of choice.
