About BrownNoise.com

One sound, one button, no catch. This page explains why the site exists, how the loop was built, and who is behind it.

Why brown noise got its own site

Brown noise spent years as a footnote under white noise, a track buried in a list of forty. Then a lot of people found that a deep, hiss-free rumble was the thing that finally let them sleep or work, and started searching for it by name. A whole site for a single sound seemed excessive until we watched how people use it: at 2 a.m., half awake, on a phone with a dying battery. At that moment nobody wants a catalog. They want the sound to start.

So BrownNoise.com does one thing. Open it, press play, and a low rumble runs for ten hours or more. There is a sleep timer, a volume slider, and a Black Screen button, and that is the full feature list on purpose.

How the loop was made

A ten-hour file would be wasteful, so the player repeats a shorter master instead. The trouble with repeating audio is the seam: a tiny click or dip every time the track wraps, which is exactly the kind of sudden change that wakes a light sleeper. Our master is a loop-cleaned .wav in which the tail is crossfaded into the head over 150 milliseconds at equal power, so the join carries no bump in level and no audible edge. The cleaned master is then encoded to AAC, downloaded once, and repeated from memory, so a whole night costs one quarter-megabyte download.

The result is a rumble that sounds the same at hour eight as it did at minute one. If you ever hear a tick or a gap, that is a bug, and we would like to know about it.

No ads, no accounts, no tracking of your sleep

An ad breaking in at 3 a.m. defeats the purpose of a sleep sound, so there are none. There is no login, nothing to install, and the page never asks for a notification permission. The site uses the minimum analytics needed to know whether it is working, governed by the cookie banner you can reopen from the footer at any time, and it collects nothing about when or how long you sleep.

The same idea runs in our mobile app for people who want the sound offline or mixed with rain, ocean, or a fan. The app is optional. This page will keep working without it.

Who makes it

BrownNoise.com is built and run by Slumber Studios, the trading name of Slumber Group, LLC, a sleep-audio company based in Durham, NC. The company was formed in 2019 and makes the apps Deep Sleep Sounds, Bedtime Fan, and Slumber, along with a set of sleep podcasts and audiobooks. The full company story, team, and press facts are on slumberstudios.com.

A note for the curious: on Google Play the app shows the package id com.kitefaster.whitenoise. Kitefaster was one of the two companies that merged to form Slumber Studios, and Android package names cannot be renamed after publication, so the old name stays. It is the same app and the same company.

How the health claims are written

Sleep is close enough to health that we hold the copy to a stricter standard than a normal marketing site. Every figure on this site, from arousal counts in a sleep lab to safe volume for a nursery, is tied to a named primary study, and the numbers are quoted as the study reported them, not rounded up to sound better. Where the research is thin, and for brown noise it usually is, the page says so.

Longer reviews of each topic live on the Slumber Studios blog, where the sources are laid out in full. None of it is medical advice. Sleep that goes wrong most nights, snoring with pauses in breathing, or ringing in one ear are all reasons to talk to a clinician rather than to adjust a volume slider.

Press and partnership inquiries go through the Slumber Studios press page. Questions about the mobile app, including subscriptions, refunds, and playback problems, are answered in the app FAQ, which lives on our sister site because this one ships no FAQ of its own. If the loop on this page ever clicks or stalls in your browser, the FAQ explains how to reach support.
