I am interested in examples of sound(ing) art in public spaces. That is, not so much in temporary sound(ing) art works but in permanent sonic interventions meant to improve the sonic quality of a public space. Anybody around who knows of some concrete examples? Any literature on this topic? Any “best practices” by which I mean concrete collaborations between a sound artist and architects, urban planners, engineers, city governments, etc.?

One example springs immediately to my mind: Champ Sonique, the soundart installation by Mo Becha in Amsterdam, placed onder a viaduct, not far from our office at the Veemkade. Realised in 2005 and still in working function, which is quite special for a soundart installation in public space. https://www.amsterdam.nl/kunstencultuur/kunst-openbare/kunst-openbare/kunstwerken/amsterdam-stadsdeel-0/centrum/champ-sonique/
It changes and enhances the athmosphere of the place. Improvement? That’s in the ear of the beholder. But it fits with your query.
All the best, Michiel
