What does white noise sound like?
White noise has equal power per unit of frequency across its spectrum. Because higher octaves cover wider frequency ranges, the result can sound bright and hiss-like. Think of a steady shhh texture rather than a repeating melody.
This page generates a digital noise signal in your browser. Your speakers or headphones affect how you hear its high and low frequencies.
How to play white noise online
- Lower your device volume before you start.
- Press Play my mix and adjust the master volume gradually.
- Keep the other channels at zero for white noise alone, or add pink and brown noise for a warmer blend.
- Use the stop timer when you want the session to end automatically. Pausing resets the countdown.
Choose a brightness that suits you
If white noise feels too sharp, try pink noise for a softer upper end or brown noise for a deeper rumble. You can switch pages below or use the three sliders to compare them in the same mixer.
| Sound | Character | Start here if you prefer |
|---|---|---|
| Brown noise | Deep and bass-heavy | A low rumble |
| Pink noise | Balanced and softer at the top | A gentler wash |
| White noise | Bright and hiss-like | A crisp, airy texture |
A few things to know
Do I need headphones?+
No. Speakers can play the sound too. Headphones change the listening experience and can make small adjustments easier to hear. Start at a low level either way.
Can white noise block every distraction?+
No. This generator adds background sound; it does not cancel sound electronically or provide hearing protection. Choose a comfortable level rather than trying to cover every outside noise.
Will it continue if I lock my phone?+
That depends on your browser, device, and battery settings. Background or lock-screen playback is not guaranteed. Try a short session on your device before relying on uninterrupted playback.
All sound is synthesized locally. No microphone permission, account, or audio upload is required. These noise colors are background sounds, rather than recordings of ASMR triggers.
