How to use

  1. Press Play. The page loads a rain + thunder + brown noise preset — you don't need to configure anything.
  2. Lower the master volume to a comfortable bedtime level (40–50% works for most people).
  3. Turn on the 30m or 60m sleep timer. The mix fades out in the last few seconds to avoid an abrupt stop.
  4. If thunder feels too busy, open the Thunder layer and drop its Probability or raise its Min delay.

FAQ

Is there a timer that stops the sound after I fall asleep?

Yes. Pick 15m, 30m, or 1h from the master bar. The engine schedules a linear fade-out a few seconds before the timer ends and pauses cleanly.

Why brown noise instead of white?

Brown noise emphasises low frequencies; it masks low-end bumps (traffic, footsteps) without the hissy top-end of white noise, which most people find easier to fall asleep to.

Can I customise the mix?

Yes — adjust any layer's volume, mode, or behavior, or open the full mixer to add more sounds. Share generates a link that reopens your exact mix.

Why this specific mix

Three layers, each doing one job:

  • Rain (loop, ~65%) — the steady masking layer. Covers household noise
    without pulling focus.
  • Thunder (random, low) — low-probability distant rumbles. Adds realism so
    your ear stops predicting the loop.
  • Brown noise (loop, ~25%) — fills in the low-end the rain doesn't cover,
    which is where most sleep disturbances live.

Together they behave like a real, distant thunderstorm. Your brain files it
as "safe background" and lets go.

Tuning tips

  • If you wake to thunder cracks, set Thunder → Max delay to 30–40s and
    Probability to 0.4. Rumbles will feel much rarer.
  • For lighter sleepers, drop brown noise to 15% instead of killing it —
    the low-end cover is the part that matters.
  • Pair with a 45m timer. Most people fall asleep in under 20 minutes; the
    fade kicks in around the time you no longer need masking.
