The best way—with a few exceptions!—to use white noise at night is with an iPhone or iPod docked in some kind of speaker-thing. Or from your computer to speakers! (As long as everything else is shut off.) Whatever is in the room, it'll work. Don't go crazy. Don't try to "game" the "system." You go to sleep war with the sleep aids that you have. You set that puppy to "repeat one" track and turn off shuffle and boom, done. I personally find that if I turn my speakers away from the bed, so that sound is bouncing off the walls and around the room, I get more out of it. And then I use it on headphones on planes. Here is my guide to everything in my white noise rotation.
Brown Noise
From Simply Noise
Nice, but very flat. Doesn't have gradations in tone. Does a decent standing fan imitation though. But slightly forceful. Their white noise and pink noise are not ideal.
White Noise Blowdryer
From "White Noise"
Do you like hairdryers? Well, here's a heinous, irritating recording of a hairdryer for you!
Victoria Falls
From WhiteNoiseMP3s.com
This has a nice "wide scope" sound. The waterness of it is not distracting. The full 66 minutes of this "quasi-binaural field recording" has both low and high tones, which is important, but is concentrated in the medium spectrum. Because it's "real audio," it is actually random noise, and patternless, which is terrific. Feels like: sleeping in a hammock without all the discomfort and bugs. Downside: you might wake up having to pee desperately. (...)
3 Hour Nap
From White Noise Therapy Volume 2
Oh man. This is deep. It's not good for snorers. But it is great for sleeping on your own. Best possible use for this is actually playing on your iPhone from under your pillow. It's a dreary kind of drone, but when close to your head at low volume, it's extremely soothing—the way you'd imagine a train ride should be, but never is, here in disappointing real life. Can be weird on planes, as it's very similar to wind noise and actually somehow embeds with the plane noise.
Sleepy Jet Cabin
From WhiteNoiseMP3s.com
Speaking of. Ugh! I don't really want my plane to sound MORE like a plane.
Deep Sleep Therapy
From Deeper State: White Noise for Infants
This is like a frosty white cocoon of deep noise. Excuse me I'll be righ zzzzzzzzzzz. Best for sleeping alone. Some of the other cuts on this classic album are decent too. (See also: "Safe and Sound" and "Snugglebug." Avoid "Goodnight Moon" and "Counting Sheep." Too shrill.)
