The sound of skating on thin ice

Henrik Trygg: “This is how 45mm new black ice sounds like. Don’t forget to put on the sound. Recorded on Lissma Kvarnsjö outside Stockholm the 5th of December.” (Previously)

It’s beautiful and a little bit scary. See (below) a cool NPS video about the weird sounds that ice make. The same phenomenon, acoustic dispersion, is often heard in wind-whipped metal cables. It’s the foley artist’s secret sauce for making laser-gun sound effects that don’t register as synthesized.
