White Noise Generator

What this tool does

White Noise Generator synthesises white, pink and brown noise live using the Web Audio API, no audio file is ever downloaded or streamed, with an adjustable volume, useful for masking distracting background sounds during focus or sleep.

Masking distracting background sounds during focused work or sleep often means playing some kind of steady noise, but downloading an audio file or streaming one from a video platform is more overhead than the task really needs.

This tool synthesises the noise directly in your browser using the Web Audio API, no file download, no streaming, no ads, just press play for a continuous, adjustable-volume noise signal in your chosen colour.

How to use White Noise Generator

1. Choose a noise colour: white, pink or brown.
2. Adjust the volume to a comfortable level.
3. Press Play, and Stop whenever you’re done.
4. Switch colours at any time to compare how each one sounds.

Tips for better results

• White noise has equal energy across all audible frequencies, a flat, hissy sound, the most commonly recognised "static" type of noise.
• Pink noise reduces higher frequencies relative to white noise, producing a softer, often more pleasant sound that many people find more comfortable for extended listening.
• Brown noise reduces higher frequencies even further, producing a deep, low rumble, like distant thunder or ocean waves, favoured by some for sleep or deep focus specifically because of its lower register.
• Since the noise is generated live, it never loops or repeats in an obviously detectable pattern the way a short looped audio file sometimes does.

Common use cases

• Masking distracting background sounds (traffic, conversations, HVAC) while working or studying.
• Playing continuous ambient sound to help with falling asleep or staying asleep.
• Providing a privacy buffer against being overheard in an open office by masking speech cues.
• Creating a calming, steady background sound for meditation or relaxation.

Common mistakes to avoid

• Setting the volume too high for extended listening, which can be fatiguing or even risk hearing strain over a long session, start at a moderate volume and adjust down if needed.
• Expecting a dramatic tonal difference between pink and brown noise if your speakers or headphones have weak low-frequency reproduction, the deeper rumble of brown noise is most noticeable on equipment that reproduces bass well.
• Closing the tab expecting the noise to keep playing in the background, like most browser audio, it stops once the tab is closed or (depending on your browser) sometimes when backgrounded.
