Sleep

This preset combines brown noise characteristics with a gentle roll-off of higher frequencies, mimicking the soothing sounds of ocean waves or distant storms. The absence of harsh high frequencies prevents sleep disruption and promotes relaxation. Low-frequency sounds are associated with safety in evolutionary psychology, helping trigger the parasympathetic "rest and digest" response. Studies show consistent sleep sounds can help establish healthy sleep routines and improve sleep onset. The gentle spectrum is safe for all-night listening at low volumes. Ideal for: falling asleep, staying asleep, napping, relaxation before bed.
