Shannon's Journal Discussion

[Shannon]

I would prefer forest or nature sounds myself. I can sleep very easily and much better with trickling stream because I stop hearing it soon after playing, and i think the white noise induces sleep. Ultrasonic at night sometimes made me feel a bit twitchy.

Trickling stream is actually pink noise. The difference is that white noise is purely random, and pink noise has a specific pitch bias. Pink noise is much better than white noise because that pitch bias is what both rainfall and other natural random sounds are composed of. The human brain is much less annoyed by it.
