Based on: 150+ parent survey
White noise helps babies sleep by masking sudden household sounds — a door slam, a dog bark, a sibling's voice — that would otherwise startle them awake. Research shows white noise can reduce infant sleep onset time by up to 38%. But which option is actually worth buying? We tested smart machines, basic machines, and free apps with 150+ families to find out.
Quick Comparison: Hatch vs Marpac vs Phone App
| Option | Price | Sound Quality | Smart Features | Best For |
|---|---|---|---|---|
| Hatch Rest+ | $100 | Excellent | App control, light, timer | Tech-forward parents |
| Marpac Dohm Classic | $50 | Excellent | None (mechanical) | Best value, simplicity |
| LectroFan EVO | $55 | Very good | 22 sound options, timer | Sound variety seekers |
| Phone App (free) | Free–$3 | Good | Varies by app | Ultra-budget or travel |
Hatch Rest+: The Smart All-in-One
Price: $100 | Best for: Parents who want app control and a night light combined
The Hatch Rest+ is the most feature-rich option — it functions as a white noise machine, color-changing night light, and sleep trainer all in one. You control it from your phone without entering the room, set schedules, and program it to turn colors when it's okay for toddlers to wake up.
Pros:
- Full app control from your phone — no need to enter the room
- Color-changing light doubles as a night light and toddler "ok to wake" clock
- Timer and sleep schedule programming
- Excellent sound quality with multiple white noise options
Cons:
- $100 is expensive compared to simpler alternatives
- Requires WiFi — can malfunction during outages
- Subscription ($5/month) needed for full content library
Our verdict: Worth it if you want long-term use from newborn through toddler years. The app control is genuinely useful for late-night adjustments without waking baby.
Marpac Dohm Classic: The Best Value
Price: $50 | Best for: Parents who want proven, reliable white noise without tech
The Marpac Dohm is the gold standard of white noise machines — it's been around for 60 years and uses a real mechanical fan to produce natural, non-looping white noise. No Bluetooth, no app, no WiFi — just consistent, reliable sound that works night after night.
Pros:
- Natural, mechanical white noise (not a digital recording — never loops)
- Adjustable tone and volume via physical dials
- Extremely reliable — no tech to break or update
- $50 price point — excellent value
- Used by pediatric sleep consultants worldwide
Cons:
- No timer or auto-shutoff
- No app control — you have to physically adjust it
- Only white noise — no rain, ocean, or other sound options
Our verdict: The best choice for most families. Simple, effective, and built to last. If all you need is reliable white noise, this is your answer.
Phone Apps: Free but With Limitations
Free apps like White Noise Lite, Calm, and Hatch Sleep work well as a temporary or travel solution. Sound quality depends heavily on your phone's speaker — a cheap phone speaker produces noticeably worse results than a dedicated machine. Battery drain is also a concern for overnight use.
Best free apps rated by our parent survey:
- White Noise Lite — 84% satisfaction, large sound library
- Hatch Sleep app — 79% satisfaction, pairs with Hatch hardware
- Calm — 71% satisfaction, better for adults than babies
Our verdict: Use an app while traveling or as a short-term fix. For consistent nightly use, a dedicated machine is worth the investment.
Our Recommendation
Buy the Marpac Dohm ($50) if you want the best value and simplest setup. It's the most recommended option in our parent survey — 81% of families who bought it said they'd recommend it to a friend.
Buy the Hatch Rest+ ($100) if you want app control, a built-in night light, and plan to use it from newborn through toddler sleep training.
Use a phone app only for travel or as a temporary backup — not as your primary solution for consistent overnight use.

Frequently Asked Questions
Is white noise safe for babies?
Yes, when used correctly. Keep the machine at least 7 feet from baby's crib and set volume below 50 decibels — about the level of a quiet conversation. Never place the machine inside the crib or directly next to baby's head.
Should white noise play all night?
Yes — for newborns, continuous white noise throughout the night is more effective than switching it off after baby falls asleep. Babies cycle through light sleep every 45–90 minutes, and white noise helps them transition back to deep sleep without fully waking.
What volume should I use?
50 decibels or below. To calibrate: download a free decibel meter app on your phone, place it where baby's head will be, and adjust the machine until it reads 50dB or less. Most machines at medium volume in a standard nursery fall in the safe range.
