play --show-progress -c 2 --null synth 01:00 brownnoise \
reverb 19 vol 0dB bass 6 treble -3 repeat 558
It sounds like a big waterfall, or like a continuous wave crash. And it's stereo. :)
EDIT: Or this:
play --show-progress -c 2 --null synth brownnoise \
reverb bass 6 treble -3 echos 0.8 0.9 1000 0.3 1800 0.25
Stupid question: Is it necessary to play something through a pair of noise canceling headphones if you just want to "cancel noise" with them?
Not with the ones I'm familiar with (Bose QC-15). You have to turn the headphones on to engage the 'active' noise cancellation, but you don't have to be listening to anything. In fact, you can unplug the cable from the ear piece completely and still hear (not hear?) the effect.

White and brown noises are slightly different.
You could check them out here http://simplynoise.com/
Excellent link! And the terms are explained, too.
EDIT: I just clicked the link 'simply rain' on that site- that is more like what I listen to.
These days, I tend to listen to this:

I have a music composition and conducting background, so any kind of music ends up distracting me at some level.
Brown noise helps me concentrate a fair bit. Personally, I've got SimplyNoise generating brown noise in oscillation mode which sounds a bit like waves.

Yikes. What terrible branding!
"Green noise" is better, sort of honest, and obvious.
They are engineering terms, not marketing terms. The 'colors' are to give you an analogy of sound frequencies in the spectrum: White is a blend of all (audio) frequencies with equal intensities; with pink noise, the intensity falls off at higher frequencies (1/f), and with brown noise the intensity falls off faster at higher frequencies (1/f^2).
Yep. More detail (with samples) here: http://en.wikipedia.org/wiki/Colors_of_noise
