NoiseHaven Help Documentation

A complete guide to NoiseHaven, from your first mix to the gentle alarm.

Last Updated: November 12, 2026

1. Getting Started

NoiseHaven has a player bar under the five tabs. Mix is where you build a mix of up to eight sounds; Sleep has the timer, the alarm, a breathing guide, the screen-off loop and the sleep diary; Focus runs work rounds with breaks; Tones has brainwave beats and sounds shaped around tinnitus; Saved keeps your mixes and makes a backup file. The player bar stays under the site's header while you use the tool: the play button, the name of the mix, the volume, a quick way to the sleep timer and the bedside screen.

2. The 35 Sounds

The sounds come in six kinds: Noise (white, pink, brown, deep brown, grey, green, blue and violet), Rain and water (rain, rain on a tent, rain on the window, thunder, ocean waves, a stream, a waterfall, under water), Nature (wind, wind in the trees, birdsong, crickets, frogs, a campfire), Indoors and travel (a fan, an air conditioner, a plane cabin, a night train, a car on the motorway, a cafe, typing, a clock), Calm and music (singing bowls, wind chimes, a soft drone, a tanpura) and Baby and body (a heartbeat, shushing, a cat purring). Each is made live from a small model with a little chance in it, so it never loops.

3. Your Mix

Tap a sound in the library to add it; tap it again to remove it. Each row of Your mix has a volume slider, a mute button, an arrow for more settings and a remove button. More settings holds the sound's own controls (for example how hard the rain falls, how often the thunder rolls, the key of the tanpura and which string it starts on), a darker or brighter tone, its direction and distance, and Drift a little. Tone of the whole mix, under the stage, makes everything darker or brighter. Clear empties the mix, with Undo for a few seconds.

4. The Sound Stage

The stage is a round room seen from above, with you as the head in the middle facing Front. Drag a dot to move its sound: to the side to hear it from there, further out to make it quieter, softer and more distant, and behind you to make it a little duller. The halo round each dot follows how loud the sound is at that moment. Spread out places the sounds evenly around you, All close brings them near, and Let sounds drift makes each one move and swell a little. With the stage selected, Enter picks the next sound and the arrow keys move it; the new place is read out. Brainwave beats and tinnitus sounds play inside your head and show as rings round the listener.

5. Ready-made Mixes and the Library

With an empty mix, twelve ready-made mixes appear beside the library, and all twelve are on the Saved tab. Each shows a small picture of where its sounds sit. In the library, the chips show one kind of sound at a time and Find a sound searches names and descriptions.

6. The Sleep Timer

Choose how long (15 minutes to 3 hours, or Until a time), how long the fade lasts (10 seconds, 1, 5 or 15 minutes) and what happens at the end: Stop, or Keep playing quietly at a fifth of the volume. Start timer starts the mix if it is not playing. While it runs, the time left shows on the Sleep tab, in the player bar and on the bedside screen; 15 min more adds time and brings the volume back. The fade never takes more than half of the time chosen.

7. The Gentle Alarm

Set the time, what to wake to and how long the sound takes to rise (1 to 15 minutes). Set alarm keeps the browser's sound ready; Hear it now plays a short version with an eight-second rise. When it rings, a dark screen shows the time with Snooze (5, 9 or 15 minutes) and Turn off, and after the rise a soft bell rings every half minute until you answer. The alarm rings only while this page stays open; while the tab is hidden the browser slows its clock, so a timer set for the moment itself wakes it. If the alarm is found up to ten minutes late it rings and says how late; later than that, a note says it was missed. A time inside the hour skipped when the clocks go forward rings when they jump.

8. Breathing, the Bedside Screen and the Screen-off Loop

Breathe to settle shows a circle that grows as you breathe in and shrinks as you breathe out, in one of three patterns: 4-7-8 (in for 4, hold for 7, out for 8), In 4, out 6 (about six breaths a minute) and Box 4-4-4-4, for 1 to 10 minutes. With Let the sound rise and fall with my breath, the mix swells as you breathe in and settles as you breathe out. If you feel dizzy or short of breath, stop and breathe normally. The bedside screen is a dark clock with your mix and the timer, in white, amber or red at three brightness levels. Keep playing when the screen is off records your mix as a two-minute seamless loop for phones that pause web sounds when the screen locks; after changing the mix, Record it again.

9. The Sleep Diary

Each time you listen for 10 minutes or more, the diary notes when and what you listened to (a stretch is never counted longer than the time that has passed). In the morning, the Sleep tab asks how you slept the night before, from Badly to Very well, or you can skip the night. Each entry can be rated or deleted later. Once two or more rated nights share a sound, Your ratings by sound shows the average rating on nights that sound played. It shows what went with your better nights, not what caused them. The diary keeps the last 200 entries.

10. Focus Rounds

Choose 25 + 5, 50 + 10, 90 + 20 minutes or My own (work 1 to 240 minutes, break 1 to 60, long break 1 to 90, and 1 to 12 rounds before the long break). Start focusing begins a work part; the dial shows the time left and dots show the rounds. In the breaks the sound pauses, keeps playing or changes to another mix. Ring a soft bell and Start the next part by itself can be turned off. The tab's title shows the time left while the rounds run. Time focused shows minutes for each of the last seven days; a stretch counts at most the length of the work part, so a computer asleep in the middle adds nothing.

11. Brainwave Beats

Choose how the beat plays (Binaural, which needs headphones, Monaural or Isochronic), a beat from 0.5 to 40 hertz with the slider or one of five presets named after the band of brain rhythm the beat falls in (Delta 2, Theta 6, Alpha 10, Beta 15, Gamma 40), the pitch of the tone (90 to 500 hertz), or a journey that moves the beat slowly: Winding down (30 minutes, 10 down to 2 hertz), Down and back up (20 minutes), Easing off (20 minutes, 14 down to 8) or Picking up (15 minutes, 10 up to 15). Add to my mix plays it under your other sounds at its own volume.

12. Tinnitus Sounds

Step 1 finds the pitch of your ringing: use headphones in a quiet room with the volume low, choose the ear, play the tone and move the slider (250 to 12,000 hertz), with Lower and Higher for small steps and the octave buttons, because ringing is easy to mistake for a note an octave away. Step 2 adds a sound shaped around that pitch to your mix: Notched noise (soft noise with the pitch taken out, half an octave or an octave wide) or a Covering band (a narrow band of noise at the pitch). Keep it a little quieter than your ringing.

13. Saving, Sharing and Sound Files

Save names and keeps the mix in this browser; the Saved tab lists your mixes with Play, Rename, Share, Sound file and Delete (with Undo). Share makes a link with the whole mix in it; the person who opens it sees the mix named and presses Play it. Where the browser blocks copying, the link appears in a box to copy by hand. Sound file makes a WAV file of 1 minute (about 11 MB), 3 minutes (32 MB) or 10 minutes (106 MB) whose end runs into its start with no seam; a phone may run out of memory on the longest one. Save a backup file and Restore from a backup move your mixes, diary and focus times between devices.

14. Limits, Keyboard and Accessibility

A mix holds up to 8 sounds; the tool keeps up to 100 saved mixes, 200 diary entries and 400 days of focus times; a name is up to 60 characters; a backup file is up to 5 MB; a share link carries one mix. Every saved value, link and backup is checked before it is used: a setting out of range is held at its edge and anything unknown is left out. With the keyboard, Tab reaches everything, the arrow keys move along each group of choices and move a sound on the stage, and while you use the tool Space plays or pauses, B opens the bedside screen and Escape closes a window. Changes such as a sound added or moved are read out to screen readers. With reduced motion turned on, the stage, the breathing circle and the windows do not move.

15. Privacy and How It Was Checked

Every sound is made on your device and nothing you play, save or write is uploaded; the tool asks no outside service for anything. Like every page on ZeroDataUpload, the page shows ads through Google AdSense and counts visits with Google Analytics; the Privacy Policy explains both. A share link's mix is taken out of the address before those load. Before publishing, the tool was compared with separate programs written from the rules on this page: 154,944 cases in 17 groups, among them the noise generators sample by sample, the slope of each colour of noise, the filters, the beats and the tinnitus notch, the places on the stage, the sound files read back by another program, the alarm and the timer in several time zones across the clock changes, the focus rounds, the diary, and thousands of saved states, links and backups made to break the tool. The page was then tested in a browser on phones and computers in both themes, with every sound played. The original version accepted a link that set a sound beyond its slider (rain about eight times louder than Downpour), made the half-octave notch only slightly quieter at the ringing's pitch, rang an alarm hours late after the device slept and counted focus time while a computer slept; that is fixed.

16. Troubleshooting and Support

• Nothing plays. Tap Play or a sound: browsers allow sound only after a tap. On an iPhone, check that the ring switch is not on silent.
• The sound stops when my phone locks. Turn on Keep playing when the screen is off under Sleep.
• The places on the stage make no difference. Use headphones; on one small speaker left and right sound the same.
• The alarm did not ring. The page must stay open and the device awake; keep your phone's own alarm as a backup.
• My saved mixes are gone. They are kept per browser and device; a private window or cleared site data starts afresh. Keep a backup file.
• The sound file failed. Try the shorter length, or a computer: making the 10-minute file needs a lot of memory.
