A lower, warmer noise texture

Brown noise puts more energy toward lower frequencies than white noise. SleepMix creates it with a gently damped random walk so the signal remains bounded, rather than using a recording. Headphones and small phone speakers can sound noticeably different because they reproduce low frequencies differently. Try a low setting first; a deeper sound does not need to be louder.

Try a balanced combination

Pair brown noise with a quiet ocean layer, then lower the noise until the wave detail remains audible. For a minimal focus background, try the generator alone and use the timer for a planned break. You can add it to any existing mix without replacing the other tracks, provided there is an open slot.

Common questions

Does brown noise improve focus for everyone?

No sound works for everyone. Treat it as an optional background and use it only if you find it comfortable. SleepMix does not promise a medical or productivity outcome.

Can I save the generator in a mix?

Yes. Its type and volume are saved with the other tracks. On the next play, a fresh noise stream is generated.
