How to use this
- Brown noise is the most-loved for sleep — most people find it the least fatiguing over long sessions.
- Volume should be a touch louder than the noises you're masking, but no louder. Above 50 dB and you'll wake up tired.
- Set a 30-minute fade if your brain has already learned to associate quiet with awake. Two weeks of this resets the link.
