Blend five generated sounds into your own background mix for sleep, study, or masking office noise. No sign-up, no streaming, no files.
Silence can be loud. A ticking clock, a neighbour’s television, or traffic outside the window can keep your brain alert long after you want to sleep. Steady background sound works the other way: it gives the brain something even to listen to, so small sudden noises fade into it. This free white noise mixer lets you blend five generated sounds in your browser, with no sign-up and no audio files to download.
The five sounds are not recordings. They are made by maths inside your browser, which means they play forever without looping clicks and cost nothing to stream. White noise is equal hiss at every pitch. Brown noise is deeper and softer, like a distant waterfall. Pink noise sits between the two. Rain is filtered hiss shaped like falling water, and fan is low, steady airflow. Mixing them lets you build the exact texture your ears find calming.
How to build your mix
- Press Play, then raise one slider at a time until you hear each sound clearly.
- Blend two or three sounds rather than maxing one out. Rain plus brown noise is a common sleep mix; fan alone suits office work.
- Set the sleep timer if you want the sound to stop after you fall asleep, for example after 30 or 60 minutes.
- Press Stop when you are done. Your mix stays on the sliders, so you can restart it exactly as you left it.
Volume balance matters more than total volume. A mix that is too loud keeps you awake just like noise does. Aim for a level where you can still hear someone speaking to you in the room, but the ticking clock and the street outside disappear. If you use headphones, keep the volume lower than you think you need; ears tire faster with headphones than with a speaker.
When each sound helps
- Sleep: brown noise and rain mask household sounds without a high hiss that can feel sharp at night.
- Focus and study: fan and pink noise cover office chatter while staying boring enough to ignore.
- Babies: steady white noise at low volume can mask doorbells and voices. Keep the speaker away from the cot and the volume low.
- Travel: a mix on your phone can turn a noisy hotel room or a long flight into a steadier space.
Do not expect miracles on the first night. Your brain notices a new sound for a few nights before it starts ignoring it, just as people who live near a railway stop hearing the trains. Give a mix three or four nights before deciding it does not work, and change only one slider at a time when you adjust it.
Honest limitations
First, generated sound is not a medical treatment. It can mask noise and support a bedtime routine, but it does not treat insomnia, tinnitus, or sleep apnoea, and loud long-term headphone use can harm hearing. Second, the sound stops if your browser tab sleeps or your phone locks, depending on your device settings, so test the timer setup before the night you need it. Third, every device sounds different: a phone speaker cannot produce deep brown noise the way a larger speaker can.
Finally, keep the volume safe. If your ears ring after listening, or you need to raise your voice to be heard over the mix, it is too loud. Background sound should sit behind your life, not in front of it.
Frequently asked questions
Why mix sounds instead of playing one?
Because a single pure hiss can feel harsh or boring. A mix adds texture: rain gives movement, brown noise gives depth, and fan gives steadiness. Most people settle on a blend they could not describe, but recognise instantly.
Does it use my internet while playing?
No. The sounds are generated on your device after the page loads, so playback itself needs no connection and no streaming data.
Can I leave it playing all night?
Yes, with the sleep timer off. On a phone, keep the charger plugged in and check that your browser is allowed to play audio with the screen locked.
