I have one of those water fountains in my room and when I drift off to sleep,it seems so much easier to sleep.What is it about water cascading in a fountain thats so soothing?They should pipe this sound through out the world.Maybe we all be a little calmer.I also have those cd's that have oceans and thunder storms.Those work pretty good to.Just an observation.
Birds are attracted to that sound also..cuz of course they need water daily so they habitate toward water..lotsa bird watchers setup fountains or running water sound producing devices..some birds wont come around without that.
personally I sleep with a fan running every night of the year...be hard to sleep without it.

had a fishtank for years, now when i listen to it it gives me bloodshot eyes and a fierce grip that could crush skulls. I can't take any noise when im trying to sleep, gotta be black and silent...
I just have my computer run 24/7 in my room. It's louder than crap but it helps me sleep because it's constant noise. When the computer is off, I can actually hear my watch ticking and it drives me nuts!
