Head-to-head verdicts across 10 dimensions — noise quality, volume range, features, infant safety, value.
The mattress comparisons buyers actually search for.












Five decisions collapse this whole category into a clear pick.
The Yogasleep Dohm runs an actual mechanical fan in a dome — continuous physical noise with no loop point. Digital machines (LectroFan, Hatch) synthesize or loop recordings; cheap ones have an audible seam that snaps light sleepers awake. LectroFan's non-looping synthesis is the digital exception that works.
For babies, follow the AAP guidance: 7 feet from the crib, volume under ~50 dB, and pick a machine that can't be bumped to max by a toddler. White noise helps infants by masking household sound, not by being loud. Our white-noise tool has the infant volume cap built in if you want to test tones first.
The Hatch Restore 2 bundles sound, sunrise alarm, and wind-down routines into one bedside unit — worth it if you'll use the light-alarm half. If you just need noise, a dedicated machine (Dohm, LectroFan) does that one job better per dollar and never asks for an app login.
White noise masks broadly but can hiss; pink noise shifts energy lower and reads as 'softer rain'; brown noise is the deep rumble many adults prefer. Fan-based machines make one adjustable sound; LectroFan gives 10 fan + 10 noise variants. If you don't know your preference, digital variety wins.
$20-30 → LectroFan Micro or basic units for travel. $45-50 → Yogasleep Dohm, the 60-year reliability pick. $170-200 → Hatch Restore 2 only if the sunrise-alarm + routine features will genuinely get used — as a pure sound machine it's overpriced.
