About white noise
White noise contains every audible frequency at equal power, like the static between radio stations or the hiss of a fan. Because it fills the whole spectrum, it is effective at masking sudden sounds: voices in an open-plan office, traffic, a partner's snoring or a neighbour's television. Sound masking works because our brains notice changes in sound more than steady sound; with a constant background, a door slam or a car horn stands out less.
Some people find white noise harsh because it sounds bright to our ears. If so, try pink or brown noise, which reduce the high frequencies. For babies, studies suggest white noise can help them settle, but paediatric guidance recommends keeping it quiet (around 50 dB, like a soft shower) and the source at least 2 metres from the cot. The noise is generated in your browser without streaming.
