Noise for Insomnia

What the noise actually does

Continuous broadband noise gives your ears a stable, unchanging sound floor. Acoustically, that raises the level a new sound has to exceed before it stands out — a car door two blocks away or a dog barking down the street contrasts less against steady noise than against silence.

Whether that masking feels easier to sleep with is individual. Some people like a stable sound bed at night; others sleep better in silence. NoiseMoon is a sound generator, not a treatment for insomnia — trying it for a few nights is the only way to know which camp you're in.

Why brown is the default here

Brown noise rolls off at −6 dB/oct — deep, low, with most of the energy below 1 kHz. Many overnight listeners describe it as grounding and warm, with less of the high-frequency energy that can make lighter colors feel "active." Brown is closer to surf or distant rumble than to rain or hiss. That's a preference, not a prescription.

That said, the right color is whatever lets your brain stop scanning. Try pink if brown feels too heavy. Try one of the themed presets (Cathedral, Velvet, Submarine) if pure noise feels too clinical for sleep. A reverberant or textured noise can feel more like an environment and less like a sound effect.

How to use this for sleep

1. Press play. Brown is selected by default.
2. Adjust the volume to a quiet level — about as loud as a refrigerator hum from the next room. If it's loud enough that you have to focus on it, it's too loud.
3. Use the warm ↔ bright slider to taste. Pure brown is fairly dark; if it feels too rumbly, slide a touch toward bright.
4. Set the sleep timer if you don't want it on all night. Tap the timer button (it shows no zzz when off), pick a duration. The noise will fade out smoothly at the end — no abrupt cutoff to wake you.

Why on-device matters at 3 AM

The most disruptive thing for insomnia listeners using YouTube or Spotify isn't the loop — it's the interruption. A free-tier Spotify ad plays mid-night and shocks you awake. A YouTube mid-roll fires four hours into a sleep video. Wi-Fi drops and the stream stops, and the sudden silence wakes you because your sleeping brain notices what changed.

NoiseMoon doesn't have any of these failure modes. Once the page is loaded, the audio is generated on your device. No ads. No mid-rolls. No streaming. If your Wi-Fi dies, the noise keeps going. The phone can be in airplane mode and it works the same.

Volume guidance

Keep overnight noise quiet — quieter than a normal conversation, and clearly quieter than your alarm. If you sleep with earbuds, go quieter still and follow the same hearing-safety habits you would with music.

A reasonable test: if you can comfortably whisper to a partner over the noise without raising your voice, the volume is in a sensible zone. If you have to project, it's too loud.

If sleep has been hard for a while

NoiseMoon is a sound generator, not a treatment. If difficulty sleeping has been going on for weeks or months, or your sleep is unusually disrupted (trouble falling asleep most nights, waking many times, daytime impairment), talk to your doctor or a sleep clinician — they can assess what's going on and recommend care suited to you.
