What if we had a thread for sounds and places? I am not thinking of generic sounds (waves crashing; train breaking; lofi chill ambient beats) in generic places (seashore; metro line; advanced stage capitalism), but unique sounds at unique places.
Such as the directed amplification of the Denge sound mirrors near Kent. It was built as an early warning system against air raids, and I guess standing there listening was someone’s job.

Or the Morske orgulje in Zadar, an artwork of urban sea organ played by waves by Nikola Bašić.

Or the reverb of University of Copenhagen new bike parking facility at the Amager “KUA” campus. What were the architects thinking? I cannot tell, but it sounds incredibly satisfying, I’ve only ever encountered that much reverb on ambient synth videos on Instagram.

Or the magnificent and also incredibly loud opera of sound as the tram 903 passes under the gargantuan Ruhrort harbour from Duissen to Auf dem Damm in Duisburg. The tram reaches formidable speed, becoming itself a character in the opera, and down under the harbor it is hard to say what composes the sublime and immersive soundscape.
I would be open for us to understand both “sound” and “place” with very open minds… Intentional, unintentional, misintentional… natureculture… but I would very much like to think of specific and unique sounds and places.
Two out of four examples above are both formed by concave concrete architecture for infrastructural purposes – a narrow start of a thread from me, apologies! Such a thread would not need to be about architecture, the above are just some examples I came up with from the top of my head. Maybe I should only mention the third and fourth, ones which I have experienced personally, and not the first and second ones which I haven’t (yet). Karen Collins speaks about “sonic fingerprints” in her stellar 2020 book Studying Sound, although what she writes about and invites us to observe include fingerprints of also e.g. people.
I also have a memory of a special hum, but I cannot remember where it is.
Can you think of some places like that? What does it sound like, and what is the connection between that sound and that place?
