Quietest bells of anything in Sleep (gain down at 0.25), and pink noise standing in for the usual brown-noise base, which gives it a noticeably softer edge than Drift or Night Wind. No wind, no rain, nothing textured layered on top, just the pink noise itself doing almost all the work.
A good pick if you or whoever you share a room with is more sensitive to low rumble than to noise in general. Pink noise sits higher and softer than brown, so it masks without that same felt-in-the-chest weight. As sleep music goes this is the gentlest option on the site, built to be barely-there rather than enveloping.
The pink noise itself is generated live rather than played from a static file, so even something this minimal keeps subtly changing shape across a full night instead of holding one static texture.
