No account, no app, no advert before it starts. Press play and it loops for as long as you leave the tab open. Eight other sounds are on the same page if white turns out not to be the one for you.
The file plays from our own servers, not from a video site, so nothing else starts afterwards and nothing is recommended to you. The audio is licensed for commercial use and the proof is written down, track by track.
White noise is a sound that carries the same energy at every frequency you can hear. That is the whole definition: not a recording of something, a shape. It sounds like a fan, or like the hiss between two radio stations, and it is the brightest of the noises for exactly that reason, because the high frequencies are in there at full strength.
What it does is masking. A sudden sound stands out against a quiet background the way a lamp stands out in a dark room. Fill the background and the same lamp is one light among many. It is the reason you cannot follow the next table's conversation in a busy café while you can hear a whisper in a library.
So it is good against voices and sharp, high sounds: a conversation through a wall, a keyboard, cutlery, a notification. It is much weaker against low, heavy sounds that pass through walls anyway, like traffic or a drill two floors down. For those, brown noise gets closer.
It does not make the noise go away. It makes the noise stop being an event.
One thing worth saying plainly, because most pages about this do not say it: whether it helps you is not settled, and it is not the same for everyone. Some people work better with it and some are distracted by it. Five minutes with the volume low will tell you more than any article, this one included.
They are three answers to the same problem, and the difference is real rather than a matter of taste alone.
Equal energy across the whole range you can hear, high frequencies included. It is the brightest of the three, and the one that covers voices and sharp sounds best. Some people find it harsh after a while.
The same idea with the energy weighted towards the low end: deeper, closer to a waterfall heard from far away. Softer on the ears over long stretches, less effective against high-pitched sounds.
Not a flat spectrum but a recording. It moves a little, which some people prefer and others find distracting, and it carries a meaning the other two do not: it sounds like weather, not like a machine.
Three different sounds, one honest answer: which one works is not a fact about the sound, it is a fact about you and about the room you are in. They are all free here, so the cheapest way to find out is to try each for five minutes.
Sometimes the room is already quiet and the hour still goes nowhere. That is a different problem, and a sound does not fix it. What tends to work is an appointment: a set time, and one other person on a video call who booked the same one, each doing their own work in silence. Rooms open every fifteen minutes, day and night.
Reading the clock…
Yes. It plays straight on this page, with no sign-up, no card and no advert before it starts. The other eight sounds on this page work the same way.
It loops for as long as you leave the tab open. The track is five minutes long and starts again by itself; inside WeFocusBuddy the loop also gets a short crossfade so the seam is less noticeable.
Yes. Browsers keep audio going in a background tab. If your phone stops it when the screen locks, that is the phone saving battery, not the page.
White noise carries the same energy at every frequency, so it is brighter and better against voices. Brown noise is weighted towards the low end, so it is deeper and gentler over long stretches. Both are on this page.
