Sound and darkness, together
Steady noise with a pure black display gives you the sound without the glow a video or an app keeps throwing at the ceiling.
Broadband noise covers traffic, neighbours, snoring, keyboards, and hum far better than music, because there is no pattern to follow.
A black screen removes visual distraction while the noise stays constant and uneventful — no track changes, no lyrics, no ad break.
Leave a phone or tablet running noise on a dark screen instead of a bright looping video with autoplay and recommendations.
How it works
A practical noise guide
Most people end up playing white noise from a video site, which means a lit-up screen, a progress bar, an advert before the sound starts, a recommendation panel afterwards, and a file that loops every ten minutes whether you notice the seam or not. This page removes all of it. The noise is synthesised live in your browser, the display goes pure #000000 black, and nothing else happens until you stop it.
All three are broadband sounds containing every audible frequency at once; what separates them is how the energy is weighted. White noise is flat across the spectrum and sounds bright and hissy, like an untuned radio. Pink noise reduces the higher frequencies so the result sounds balanced and natural — most people describe it as steady rain. Brown noise rolls the highs off further again and sounds like a deep rumble, distant surf, or a waterfall heard through a wall.
There is no correct answer, only a fit. White is the most effective at covering sharp, high-frequency sounds: voices through a wall, keyboards, cutlery, a television in the next room. Pink and brown feel gentler over several hours, which is why they win overnight and during long stretches of focused work. Switch between them while the sound is playing and pick whichever one you stop noticing first — that is the one that is working.
Sound is only half the problem. A bright screen in a dark room is a distraction on its own, and light in the hour before sleep is one of the few things about a bedroom that is genuinely worth controlling. Playing noise from a video means keeping a lit display in the room all night. Here the display goes fully dark and stays that way, so nothing is competing with the sound.
On an OLED or AMOLED panel it goes further: black pixels are switched off rather than lit, so the display emits no light at all and draws almost no power for the screen. On an LCD the backlight keeps running, so drop the brightness before you go fullscreen — the panel will still be far dimmer than any video.
Noise works differently from music. A song gives your attention something to follow: a melody, a lyric, a change of section. Broadband noise gives it nothing. Instead of competing with the sound you are trying to ignore, it raises the floor around it, so the neighbour’s door or a passing car no longer stands out sharply enough to pull your attention.
That is also why you need less volume than you might expect. The aim is to sit just above the sounds you want smoothed over, not to bury them. If the noise is loud enough that you notice it as a sound in its own right, it is almost certainly louder than it needs to be — and sustained loud audio is worth avoiding, especially through headphones or near a child.
Set the sleep timer if you would rather the sound stopped once you have drifted off — 15 minutes is enough for many people, while others prefer it running until morning. Leave it Off and pair it with the 10-hour session if you want both sound and a dark, awake display all night. Keep the device on a charger, put it an arm’s length or more from your head, and keep the tab in the foreground, since switching apps on a phone can suspend the audio.
For a baby, place the device well away from the cot and keep the volume low — noticeably quieter than a normal conversation. This is a browser utility, not a sleep aid or a medical device: if you are dealing with persistent insomnia, tinnitus, or a child who will not settle, that is a conversation for a doctor rather than a page setting.
The noise is generated with the Web Audio API from a buffer created on your own device, so there is no file to download, no bandwidth cost, and no loop point for your ear to lock onto. It keeps working if your connection drops after the page loads. Nothing about your session is recorded, and there is no account, sign-up, or subscription anywhere in the tool.
If you only want the dark surface, the plain black screen does that alone. If you want a file instead of a page, download a black screen wallpaper or a black screen image. On an iPhone, the iPhone black screen page explains how to get the display fully edge to edge in Safari — noise included.
Helpful answers
It is a page that plays continuous noise while the display stays pure #000000 black. You get the sound of a noise machine without the light, the video player, the adverts, or the recommendations that come with playing noise on a streaming site.
All three contain every audible frequency at once, but weighted differently. White noise is flat and sounds bright, like an untuned radio — best at masking sharp sounds such as voices and clicks. Pink noise rolls off the highs and sounds like steady rain. Brown noise drops them further and sounds like a deep rumble or distant surf, which many people find easiest to sleep to.
Most people prefer pink or brown noise at night because the softer high frequencies feel less harsh over hours. White noise masks intermittent sounds most effectively, so it suits a noisy street or a thin wall. Try each for a few minutes at low volume and use whichever you stop noticing first.
No. The sound is generated by your browser in real time rather than streamed from a file, so there is no loop point, no seam, and no moment where the same second comes round again — which is exactly what your ear would otherwise start to anticipate.
Yes. Going fullscreen changes only the display. The audio continues until you pause it, the sleep timer ends it, or you close the tab. Switching to another app on a phone may suspend it, so keep the tab in the foreground overnight.
Only to load the page. Nothing is streamed. The noise is synthesised locally with the Web Audio API, so it costs no data, works on a slow connection, and keeps running even if your network drops.
Keep the volume low — comfortably below conversation level — and place the device away from your head, especially for a baby. Sustained loud sound is the thing to avoid. Use the sleep timer if you would rather the noise stopped once you are asleep, and speak to a doctor about persistent sleep problems rather than relying on a browser tool.
Yes. Choose 15 minutes up to 8 hours and the audio fades out on its own. Pair it with the 10-hour session if you also want the display to stay awake, and keep the device on a charger.
