Generatore di rumore bianco, rosa e marrone.
Ascolta rumore bianco, rosa o marrone per concentrarti, coprire i rumori o dormire, con volume e timer con dissolvenza.
White noise has equal energy at every frequency (a hiss); pink noise drops 3 dB per octave (like rain); brown noise drops 6 dB per octave (a deep rumble, like a waterfall). Many people use them to mask distractions or to fall asleep; keep the volume moderate, especially for babies, and do not rely on it as a medical treatment.
The sound is generated in your browser and fades out when the timer ends. Keep this tab open; some phones pause sound when the screen locks.

Noise is synthesised in the browser: white from random samples, pink with Paul Kellet’s filter (−3 dB per octave), brown by integrating white noise (−6 dB per octave), looped with a cross-fade.
Brown noise with a 30-minute timer plays a deep rumble and fades out after half an hour.
