Mikel R. NietoThe Sound of Underwater Friction Produced by Movement

This recording was made in the Mediterranean Sea with a special hydrophone designed to listen to echolocations made by dolphins. Obviously these animal communications are masked by the sound of friction, and personally I found this sound very interesting. Scientists hate it because it affects the listening of dolphins, and a special filter was built to avoid it.

Can we maybe think about this sound as an endangered sound?

In addition, this sound is created by velocity and therefore it's not yet possible to upload in a soundmap format, much as it happens in e.g. soundwalks. It's just not possible. I prefer to experiment with this limitation than to hide it. If in a soundmap one could make two markers for a single sound, we could then maybe calculate the velocity of the bodies. And the title of the piece would be so different!
