Which noise should I choose?
White noise is bright and hissy and masks voices well. Pink noise is softer and many people find it easier to listen to for long periods. Brown noise is deep and rumbly, like distant thunder or a waterfall.
Playing for a long time
Playback loops seamlessly until you stop it. Keep this tab open; some phones pause audio in background tabs, so a downloaded file in your music app is better for all-night use.
