Motorway service stations sound like swimming pools

Pausing at the service station on the M25 home, we were sitting having our coffees when I realised that the service station soundscape really reminded me of a huge swimming pool. The hum of electricity, the fraught children yelling, the huge expanses of glass reflecting all the sounds... ok the coffee-making sounds are less swimming-pool like but the din of many people in a large, reflective space was quite astounding. What a soup of noises. I drank my coffee and tuned in to the soup. Weirdly, you can't see the services at all on the aporee map; I think the satellite imagery predates this build. It feels very strange to overlay this very industrial, car-related racket onto a green field site. But I did double check the post-code and this is where the sound is. Maybe in thousands of years time aporisti will overlay this recording with the sounds of birds and trees once again.
