I just returned from a tenting trip. In a tent, one hears the sounds of night more plainly. I was struck by the fact that, try as I might, I can not distinguish the sounds of wind from those of running water. Specifically,
I should confess that my ears hear nothing above 3K hertz. Nevertheless, none of those noises sound to me similar to electronically generated white noise.
I am also a sailor, so I can report that at sea, the sounds of wind are always confused with the sounds of waves, so that I can't ask the same questions in that case.
I found a previous thread about wind noise on this forum. The answers provided had to do with vorticies. But I expect the mechanisms of noise production and transmission to be very different for wind and running water. I suspect that at least some of the water sounds are transmitted through the ground.
Are my perceptions correct; are the spectra of these diverse noise sources really so similar?
If yes, is it just coincidence or are there similarities in the noise production and transmission mechanisms?
