I am one of them folks whut cant sleep without some sort of "fan noise"
I simply cannot get to sleep in complete silence.
Therefore I have a noise machine that makes whale noises, rain, wind, all that kind of stuff though I really only ever use it in the WHITE NOISE mode.
Something I have noticed is that my ear will pick up a pattern in the noise. Almost like a repetitive kind of soft techno rhythm. Once I hear it my brain locks onto it and my brain sort of grooves along on it. It doesnt affect my sleep either. In fact it tends to help.
What's INTERESTING however is that its often a DIFFERENT pattern/beat. And it has switched up on me many different nights.
So I guess what Im asking IS...
• Does anyone have any idea how this noise is generated?
• Is it simply layers of these kinds of grooves and in aggregate they make a white noise wall?
• Is it a random groove generated each time?
