- For
- People who use ambient sound to wind down or mask noise
- Worth noticing
- Its sleep advice distinguishes everyday masking noise from timed pink-noise pulses studied in labs, and says evidence for continuous noise remains very low quality.
Field notes
The mixer offers separate levels for its sound sources, with spatial placement and distance variation available as options; the page recommends headphones for clearer 3D placement. It advises keeping playback quiet and notes that rain and ocean waves may mask background noise better than forest or bells. The site also cautions that evidence for continuous noise improving sleep is limited and directs persistent sleep problems toward medical advice.
