"Where is that white noise coming from?"<br>"I don't know, but it's so relaxing I think I'll take a nap."<br><b>squish</b>,(reply>), Oh frick I’m so bad at this—,(reply>), Yes, white noise helps you fall asleep <b>because it drowns out other noise</b> including some internally generated by your brain, and it being <b>constant</b> is what makes brain stop noticing it too, so you end up with effectively no (or little) auditory input and relax.<br><br>And here it still drowns out other noise, but is also really loud, sudden, pwlsing and moving towards you when you are supposed to pay attention to it. And yes, it is much easier to pinpoint such a wide-spectrum signal up close, and when it echoes it starts sounding more like background construction noise and does not interfere with the source.,(reply>), @OmikronWeapon does it work?,(reply>), it immediately reminded me of the white noise I use to fall asleep sometimes.
