Common problems and fixes
No sound
Check the system volume and that the tab is not muted (right-click the tab).
Binaural beats do nothing

On phones the system may suspend the page: keep the screen on or the browser in front.
Frequently asked questions
What is the difference between white, pink and brown noise?
White has all frequencies equally loud (hiss); pink softens the highs (rain); brown is deeper still (waterfall).
Does white noise help with sleep?
It masks sudden noises that wake you. Keep the volume moderate, under 50 dB for babies.
Are binaural beats proven?
Studies are mixed; many people simply find them relaxing.
Do I need to download a file?
No, the sound is computed live by your browser.
