Brown noise for overthinking, with a voice on top.

Why it works

Most brown noise pages give you the noise and wish you luck. This one starts with a story already playing over it, because overthinking is rarely solved by less sound. The noise is a soft floor at 400 Hz and below. The voice is slow and level, and it is reading about Aristotle.

The story does not need your attention. That is the design. It is interesting enough to drift toward and uneventful enough to drift away from, and you were told how it ends before it started. Take the voice out with the first button if you would like to hear what the noise does alone.

What you are hearing

• Brown noise. White noise run through a leaky integrator, so its energy falls six decibels per octave, then low-passed at 400 Hz. A low, even wash.
• The voice. The first four minutes of Aristotle, the Greatest Philosopher, a Lullable story, in a synthesised voice. It only plays if you bring it in.
• The ending. The preview lasts four minutes. Its last ten seconds are a straight fade to silence, so it never stops abruptly.

For a real recording that runs forty minutes, the Lullable iPhone app has rain, waves, a campfire and plain noise, with no voice and no music.
