Why use a noise generator for sleep?
Ambient noise, like a whirring fan, is effective at masking disturbing sounds that can keep you from falling asleep or wake you up. Unlike music, ambient noise has no melody to engage your brain, so it fades into the background while you drift off.
Which noise type is right for you?
Not all noise is created equal. Each color has a different spectral balance that affects how your brain perceives it.
White noise
Equal energy across all frequencies. Great for blocking distractions and masking office sounds.
Pink noise
More bass, less hiss. Studies suggest pink noise may improve deep sleep and memory retention.
Brown noise
Deep rumble similar to heavy rain or thunder. Many find it the most soothing for falling asleep.
How to use
Select a noise type, press play, and adjust the volume. Please note that the player's volume slider works independently from your device's physical volume buttons. For best results keep the player slider high and use your device's hardware buttons to control the loudness. The sound will keep playing when your screen locks. Works on both mobile and PC. You can also download audio files to use offline.
Safety note
Listening to continuous noise through earphones can cause hearing fatigue or damage if the volume is too high. As an alternative to earphones, use the built-in speaker on your phone or laptop, or connect to an external speaker.
