White, pink and brown noise
| Type | What it sounds like | Often used for |
|---|---|---|
| White noise | Even hiss across all pitches, like a radio between stations | Masking background sound |
| Pink noise | Softer, with more low pitches, like steady rain | Relaxing and sleep |
| Brown noise | Deep and rumbling, like a waterfall or a strong wind | Focus and blocking out speech |
Noise is a steady, constant sound that covers other noises. The three types differ in how the sound is spread across low and high pitches. People use steady sound to cover traffic, neighbours or office chatter. Research on whether it improves sleep or focus is mixed, so treat it as something to try and not as a treatment. Keep the volume low and do not play loud noise close to the ears for long periods.
What people use it for
