Frequently Asked Questions
What is the difference between white, pink, and brown noise? +
White noise has equal energy at every frequency and sounds like static. Pink noise reduces higher frequencies by 3dB per octave, producing a balanced, natural sound like rainfall. Brown noise drops off even more steeply, creating a deep rumble similar to thunder or a waterfall.
How does the auto-stop timer work? +
Set a duration in minutes before starting playback. The noise will automatically stop and the timer resets when the time runs out. You can also stop it manually at any point.
Will this keep playing if I switch to another tab? +
Yes. The Web Audio API continues generating audio even when the tab is in the background. The sound will play until you stop it or the timer expires.
Which noise color is best for sleeping? +
Most people find pink or brown noise best for sleep because they emphasize lower frequencies, which are less harsh than pure white noise. Experiment with each to find what works for you.
