Brown noise is preloaded on this page as one option for covering daytime household and street sound during a daytime sleep. It starts and fades gradually, rather than switching on and off abruptly.

Brown noise or white noise against traffic?

Brown noise is weighted toward the low end of what you can hear, with none of white noise's bright hiss (its own page has the detail). White noise, spread evenly across the whole range, and green noise, weighted toward the middle, are one tap away if you would rather try either instead. All three are generated live in your browser and never repeat.

How long should it play?

With Pro, the timer offers 15, 30, 60 and 90 minutes, or all night, which is eight hours. Without Pro, a free sound plays for fifteen minutes a day. Whichever length you choose, the sound fades out over about half a minute at the end rather than stopping suddenly, and rises over about four seconds at the start.

Blackout, earplugs and sound together?

This page cannot rank blackout curtains, earplugs and background sound against each other, because they address different things. Blackout curtains deal with light, and a background sound like this adds an even layer on top of whatever else gets through.

Listen safely

This is a sound, played back through whatever speaker or headphones you already own. It doesn't diagnose, measure, or promise anything about how you sleep, focus, or feel — it's just noise and a handful of real recordings, mixed the way you like them.

Keep the volume low enough that you'd still notice a smoke alarm, a phone ringing, or someone at the door. If you fall asleep in headphones, choose a volume and a pair you'd be comfortable wearing all night, and a session length that ends when you'd want the sound to stop.

If you use this near a baby, keep the speaker several feet from the crib, never inside or clipped to it, and keep the volume low — the same care you'd take with any sound machine in a nursery.

If your relationship with sound, or with sleep, feels difficult rather than simply restless, a doctor or audiologist is the right person to talk to. This is a mixer, not a clinician.

Is daytime sleep the same as nighttime sleep?

This page does not compare how daytime and nighttime sleep differ, a broader question involving light and body clocks that a page about background sound is not positioned to answer. A doctor is a better source for that than a website.

What volume should I use during the day?

Loud enough to sit alongside daytime household or street sound, but still at a level you would be able to hear a phone or an alarm over. The level worth checking is the one at the actual time of day you plan to sleep.

Can I use a different sound entirely?

Yes. Every noise color and real recording on the site is one tap away from this page.
