Train operator Thalys created three interactive sound billboards that each captured over 1000 noises from different cities.
The billboards were part of a campaign to encourage people to explore nearby cities. Each of the billboards represented Amsterdam, Paris or Brussels, included sound ports allowing pedestrians to plug in their headphones and hear different sounds from the regions.
