White Noise
Pure, even masking
White Noise Player
Updated 6 July 2026
White noise is a sound that contains every audible frequency at equal intensity, producing an even, full hiss — like radio static or a fan. This free player streams seamless white noise that masks distractions and loops for as long as you need.
What does white noise sound like?
White noise sounds like steady static or a hair dryer — a constant, full hiss with energy spread evenly across the whole hearing range. That even spectrum is what makes it so good at covering up sudden, unpredictable sounds like a door, a voice or a car going by.
What is white noise good for?
White noise is best when your main goal is to mask a noisy environment: traffic, talking, a snoring partner or office chatter. It is also widely used to settle babies and to create a consistent sound bubble for sleep and concentration. Keep it at a low, comfortable level.
White vs pink vs brown noise
White noise is the brightest and most even; pink noise is softer and more balanced, like steady rain; brown noise is the deepest, with the highs removed. If white noise feels too sharp, step down to pink or brown for a warmer, more soothing sound.
White vs pink vs brown noise
| Noise | What it sounds like | Best for |
|---|---|---|
| White noise | Bright, even hiss across every frequency | Masking sudden sounds; offices; babies |
| Pink noise | Soft and balanced, like steady rain | Relaxing and deeper sleep |
| Brown noise | Deep, warm rumble with the highs rolled off | Sleep, focus, low-rumble masking |
White noise questions, answered
Is white noise good for sleep?
White noise can help by masking sounds that would otherwise wake you, and many people fall asleep faster with it. Research is mixed and limited, so think of it as a way to control your sound environment rather than a guaranteed sleep aid.
Why does white noise mask other sounds so well?
Because it holds equal energy at every audible frequency, there is no quiet gap in the spectrum for another sound to cut through. A door, a passing car or a raised voice lands against a bed of sound that already occupies those frequencies, so it has far less contrast. The brain soon tunes the steady bed out and the room feels quieter.
Does white noise loop seamlessly?
Yes — it is a lossless, gapless loop, so there is no click or break at the loop point no matter how long you play it.
