White noise machines are the closest thing to a cheat code for new parents. The right one buys you 20 to 90 minutes of extra sleep per nap. Here are our team’s picks, all available on Amazon AU and Amazon US.

Why white noise actually works (and how to use it safely)
- The womb is loud — about 80–90 dB. Newborns aren’t startled by sound; they’re startled by silence.
- Volume cap: 50 dB at baby’s ear. Use a phone decibel app to check. Louder is an established hearing risk.
- Pink and brown noise are gentler than pure white noise — lower-frequency emphasis.
- Position 2 metres from baby’s head — never inside the cot or on the bassinet rail.
- Wean by age 2 — some kids need it longer, but the goal is sleep without dependency.
The picks — reviewed in detail
Hatch Rest 2nd Gen
App-controlled (adjust without entering the room), 11 sound profiles including pink and brown, night-light doubles as wake-up colour for older toddlers. Audio quality genuinely better than competitors — no compressed-loop hiss.
Yogasleep Marpac Dohm
A real fan in a sealed enclosure — not a recording. Mechanical sound with no audible loop point, which is what wakes some babies on cheaper digital machines. Plug in and it works for years.
Yogasleep Hushh Portable
Pocket-sized, 12 hours of battery life, USB-C rechargeable. The cheapest portable we’d trust. Goes in the change bag, the pram, or grandma’s house.
LectroFan Classic
20 distinct profiles — ten fan tones, ten white/pink/brown variants — with no audible loop on any. If you’ve been through three machines without finding the magic sound, this is the one.
Big Red Rooster 6-Sound
Under $30. Six profiles (white noise, fan, brook, ocean, rain, summer night), auto-off timer, battery option. Audio loop is short enough to detect if you listen, but most babies don’t.
What we’d skip
- “Heartbeat” plush toys for cot use. Soft toys = suffocation risk under 12 months.
- Phone apps as primary white noise. Phones overheat, batteries drain, notifications interrupt at 3 a.m.
- Machines without continuous play. A 30-min timer that wakes baby halfway through a nap is the worst of both worlds.
