Brown Noise

Brown noise is not a fart, not the fabled frequency that causes humans to loose control of their bowels.  It is a type of noise pattern like White noise or “static.”  It is the most calming and pleasing color of noise, and sounds like a far off waterfall or the hum of a turbine.  Have a listen!

Brown noise (also called red noise or Brownian noise) is named after a fellow named Brown who found an equation to model the random motion of particles suspended in liquid.  The sound spectrum that follows this pattern decreases 6db per octave, so it is more intense at the lowest frequencies and less intense at the higher.  It is these lover frequencies that add a balance to the high static-like sounds and makes for a nice muffled sound.  Here is an EQ-ed version that even further boosts the lows.

These samples will loop endlessly, but for some silly reason it isn’t completely seamless. However, you should still be able to sleep to them. Otherwise, download them from my server and loop them in your favourite software.
