Some phones, iPhones above all, pause sounds from web pages when the screen locks. This turns your mix into a two-minute recording that loops with no seam, which phones keep playing like music.

How it plays
A slightly different tone in each ear; you hear the difference as a slow beat. Needs headphones.
Or follow a journey
Whether these beats change your brain rhythm is not settled: of 14 studies reviewed in 2023, 5 found that they did and 8 that they did not (Ingendoh and others, PLoS ONE). Many people simply find them pleasant. They are not a treatment. Do not use them while driving, and if you have epilepsy, ask your doctor first.
Tinnitus sounds
Not in your mix1. Find the pitch of your ringing
Use headphones in a quiet room, with the volume low. Start the tone and move the slider until it sounds most like your ringing.
Ear
Ringing is easy to mistake for a note an octave away. If the octave buttons sound closer, keep that one.
2. Play a sound shaped around it
Sound
Soft noise with your ringing's pitch taken out.
Width
Keep it a little quieter than your ringing, so you still hear both. See a doctor if your tinnitus is new, in one ear only, beats in time with your pulse, or comes with hearing loss or dizziness, and get help the same day after a sudden loss of hearing.

How to Use NoiseHaven
Set each one
Every sound has its own volume, and the arrow on its row opens more: how hard the rain falls, how rough the sea is, the speed of the fan, a darker or brighter tone.
Place them around you
On the round stage you are the head in the middle. Drag a sound to the left, the right or behind you; further out it sounds quieter and more distant. Headphones make this come alive.
Fall asleep
On Sleep, start a timer that fades your mix out over up to fifteen minutes, open the dim bedside screen, or set a gentle alarm that rises from silence in the morning.
Focus in rounds
On Focus, work for 25, 50 or 90 minutes or your own length, with breaks between, and the mix plays while you work. A soft bell marks each part.
Save and share
Save mixes you like, share one as a link, make a seamless sound file for any music player, and keep a backup file of everything.
Why Use This White Noise Generator?
🌧️ Sounds that never repeat
Nothing is a recording. Each drop, wave and bird call is made as it plays, so an hour of rain has no loop to notice.
🧭 A room around you
Every sound has a place: in front, behind, near or far, with a little drift if you like, so a mix sounds like a place rather than a track.
😴 Made for the night
A timer that fades slowly, a bedside screen that dims to deep red, a gentle alarm and a sleep diary of how you rated each night.
🎯 Made for focus too
Focus rounds with breaks, a week of focused minutes, and steady sounds such as brown noise, a cafe or a soft drone.
🔒 Nothing uploaded
There is no account and no upload. Your mixes, diary and focus times stay in this browser on this device.
📱 Phone friendly
Large buttons, a player bar that stays in reach, and a seamless recording for phones that pause web sounds when the screen locks.
White Noise and Sleep Sounds Explained
🎨 The colours of noise
Noise is named by how its energy spreads over the pitches. White has the same energy at every pitch; pink falls 3 decibels an octave, so each octave carries the same energy; brown falls 6 decibels an octave and sounds deep. Blue and violet rise instead, and grey is shaped so every pitch sounds about as loud to the ear.
🛌 Steady sound and sleep
A steady sound can cover sudden ones, such as a door, a car or a neighbour, which is why many people sleep with a fan or rain playing. The research is not settled: a 2021 review of 38 studies rated the evidence very low (Riedy and others). Keep it quiet, and for a baby keep the speaker well away from the cot.
〰️ Beats and tinnitus sounds
Two tones a few hertz apart beat against each other; played one in each ear, the beat is heard inside the head. Whether that changes brain rhythm is still argued. For tinnitus, notched noise leaves out the pitch of the ringing; trials of notched music disagree, so it is something to try, not a treatment.
Frequently Asked Questions
What is the difference between white, pink and brown noise?
White noise has the same energy at every pitch, so it sounds like a bright hiss. Pink noise falls by 3 decibels with each octave, which gives every octave the same energy and sounds softer, like steady rain. Brown noise falls by 6 decibels an octave and sounds deep, like a distant waterfall. NoiseHaven also has grey noise (shaped so that every pitch sounds about as loud), green noise (centred on the middle pitches), blue and violet noise (rising with pitch) and deep brown noise with the hiss taken out.
Are the sounds recordings that loop?
No. Every sound is made live on your device from small models of the real thing: each raindrop, bubble, bird call and crackle is worked out as it plays, with a little chance in it. Nothing is a recording, so nothing loops: an hour of rain never repeats itself.
Does white noise help you sleep?
Many people find that a steady sound helps them fall asleep, mostly because it covers sudden noises such as traffic or a door. The research is not settled: a 2021 review of 38 studies rated the evidence that steady noise improves sleep as very low quality (Riedy and others, Sleep Medicine Reviews). Treat it as something to try, keep the volume low, and see a doctor about sleep problems that go on.
Will the sleep timer and the alarm work with the screen off?
They work while this page stays open. Many phones keep playing with the screen off; some pause sound from web pages when the screen locks, and for them Keep playing when the screen is off, under Sleep, turns your mix into a seamless recording. Leave a phone on its charger with the bedside screen showing, and keep the phone's own alarm as a backup. If the device slept and the alarm is found more than ten minutes late, it says it was missed instead of ringing.
What are brainwave beats, and do they work?
Two tones a few hertz apart, one in each ear (binaural, with headphones), mixed together (monaural) or one tone pulsing (isochronic), so you hear a slow beat. Whether such a beat changes your own brain rhythm is not settled: of 14 studies reviewed in 2023, 5 found that it did and 8 that it did not (Ingendoh and others, PLoS ONE). Many people simply find them pleasant. They are not a treatment; do not use them while driving, and ask your doctor first if you have epilepsy.
Can NoiseHaven help with tinnitus?
It is not a treatment. It can match the pitch of your ringing and play soft noise with that pitch taken out, or a narrow band at that pitch that covers it for some people. A small trial of music shaped this way found the ringing rated quieter after a year (Okamoto and others 2010); a larger one found no clear change on its main measures (Stein and others 2016). See a doctor if your tinnitus is new, in one ear only, beats with your pulse, or comes with hearing loss or dizziness.
How is it different from the site's other tools?
Prana Breathing Exercises teaches fifteen breathing techniques in depth, and the Clock has alarms, a countdown, a stopwatch and a world clock. NoiseHaven is a sound mixer first: its alarm wakes you with its own sounds rising from silence, its sleep timer fades your mix out, and its short breathing guide lets the sound swell and settle with your breath.
