What Is White Noise?

White noise contains every frequency you can hear at equal intensity — which is why it sounds like a steady hiss, similar to radio static, an air conditioner or a fan on high. Because it covers the whole range evenly, it's very good at masking other sounds: a door closing or a conversation next door gets lost in the background instead of grabbing your attention.

What People Use It For

• Focusing in noisy places — open-plan offices, share houses, cafés and libraries.
• Sleeping through disturbances — traffic, neighbours, a partner's snoring. Set the stop timer so it fades out after you've drifted off.
• Studying — a consistent sound can make it easier to settle into a task. Pair it with a 25-minute Pomodoro timer for structure.
• Privacy — reduce how clearly phone calls carry in a home office.

White, Pink or Brown?

If white noise sounds too bright or harsh, try pink noise, which is softer like steady rain, or brown noise, a deep rumble like a waterfall. Many people find the deeper colours more comfortable for long listening — switch between them with the Colour buttons above.

Listening Safely

Keep the volume comfortable and as low as still works for you, especially with headphones or when listening for hours. Long, loud listening can damage hearing. If you use white noise for a baby, keep it at a low volume with the speaker well away from the cot.
