White Noise
Classic broadband hiss
An even, bright noise covering a wide range of frequencies. A familiar option if you want a steady background rather than changes in a rain or ocean recording.

White Noise for Sleep
A steady background, without a playlist ending after ten minutes. Choose the bright wash of white noise, the softer balance of pink noise or the deeper sound of brown noise, then leave the player running for as long as you prefer.
These are original, synthesized noise tracks. No track is proven to be the best choice for everybody, and listening is not a substitute for treatment of sleep problems.

Compare the sounds
Start your background sound
Press Play to start white noise. Use the timer and volume controls when the shared player loads, or listen through the native MP3 controls if JavaScript is unavailable.
Ready: White Noise
Audio does not start automatically. On compatible iPhones, native HLS keeps the audio timeline moving across ten-minute source boundaries, including while the screen is locked. Device and browser restrictions can still interrupt playback.
Keep it simple
A bedtime routine in three steps
01
Pick a comfortable texture
Start with White, Pink or Brown Noise. Switch while listening to decide which one fades into the background most easily.
02
Set a low volume
Begin quietly. The same percentage on a phone can produce very different sound levels through headphones, a bedside speaker or a soundbar.
03
Choose a session length
Leave the timer off for continuous play, or choose 15 minutes through 12 hours from the player. The timer is a convenience, not a guaranteed safety shutoff.
Choose by sound, not hype
Compare white, pink and brown noise
All six choices point to independently rendered audio files already in the library. Tap Listen now to change the playing sound on this page; Sound details opens its dedicated technical page. No extra audio begins without your click.
Start with the three main noise colors
Their spectrum changes what you hear, not a guaranteed sleep outcome.
Pink Noise
Softer high-frequency balance
Less emphasis on the upper frequencies than white noise. Try it if a bright hiss seems sharp on your headphones or speaker.
Original DSP · 10-minute masterBrown Noise
Deep low-frequency wash
A noticeably bass-heavy sound. It can feel less bright, but a small phone speaker may not reproduce much of the low end.
Original DSP · 10-minute masterTry softer and deeper variations
If one color feels slightly too bright or too heavy, compare these original DSP alternatives.
Soft White Noise
A gentler take on white
An independently synthesized, softened alternative to the classic white-noise hiss. Compare at low volume to find what is less distracting to you.
Owner-approved original DSP · 10-minute masterWarm Pink Noise
Warm, broad mid-low texture
A distinct original pink-noise variation designed with a warmer tonal balance. Pick this when ordinary pink noise still feels too bright.
Owner-approved original DSP · 10-minute masterDeep Brown Noise
Stronger low-end emphasis
A deeper variation of brown noise. Listen at a comfortable volume, and remember that different devices reproduce bass differently.
Owner-approved original DSP · 10-minute masterPerceived loudness can change when you switch tracks. Lower the volume before comparing, especially with headphones. All six noise masters contain ten minutes of independently synthesized audio per cycle; continuous playback repeats the approved master instead of stopping at the file boundary.
Practical setup
For a comfortable night of listening
Place the speaker sensibly
Use a comfortable listening distance and avoid putting a speaker directly beside your ear. If you use headphones in bed, be mindful of pressure, cable and comfort while lying down.
Expect differences by device
White noise can sound crisp through small speakers, while low-heavy brown noise may lose some bass. A softer track on one device can sound quite different elsewhere.
Keep control of the session
The mini player remains available as you browse this site. Choose the timer, pause or stop. A locked phone may limit background tasks; the operating system can interrupt sound despite continuous HLS.
Know when to turn it off
Sound is optional. If the noise is irritating, too loud or keeps you awake, lower it or stop. Persistent sleep difficulties deserve more than a background audio track.
Frequently asked
White noise for sleep: common questions
Is white noise or brown noise better for sleep?
No noise color has been established as universally best for sleep. White noise is broadband and often brighter. Brown noise emphasizes lower frequencies. Try both at a comfortable volume and keep whichever is less distracting for you.
Can I leave the sound playing all night?
The player supports continuous playback and an optional sleep timer. On supported iPhone browsers, native HLS is intended to avoid a restart at each ten-minute boundary; other browsers use looping MP3. Internet, device power settings and operating-system behavior can still interrupt a session.
Does the ten-minute MP3 mean the sound stops after ten minutes?
No. Ten minutes is the length of each synthesized source master, not the maximum listening session. The browser repeats the MP3 or plays an extended HLS timeline, depending on its audio support.
How loud should I play white noise at bedtime?
There is no universal safe device-volume percentage because speaker output and distance vary. Start low, avoid uncomfortable levels and do not rely on the sleep timer as a safety cutoff. This page is intended for adult listening, not infant sleep guidance.
