重要なポイント
- Running ambient audio overnight without a timer can disrupt deep sleep cycles — set a 30–60 minute fade so the sound stops once you are under.
- Rain is a broadband sound (similar acoustic mask to white/pink noise) but with more variability, which most people find less fatiguing.
- An ad-free, account-free sound app avoids the worst category problem: a 3 a.m. video ad cold-starting on your nightstand.
Quick Answer
[White Noise Sleep Sounds](https://apps.apple.com/us/app/white-noise-sleep-sounds-baby/id6740737671) is a free GradFlowLab app for iPhone, iPad, Mac, and Vision Pro that plays rain, white noise, pink noise, brown noise, and other ambient presets, each with a configurable sleep timer that fades out.
Why a Sleep Timer Matters
Running ambient audio at a steady volume across the whole night sounds harmless, and for many people it is. But research on sleep and auditory stimulation suggests that continuous broadband noise can suppress REM cycles and reduce overnight memory consolidation. The practical answer is not "do not use sound" — it is "use it to fall asleep, then let it stop." A 30 to 60 minute fade is the usual sweet spot.
What's in the App
A short list of preset categories you will use most:
- Rain — light rain on a roof, heavier rain on leaves, distant thunder, rain through a window
- White noise — flat broadband for fast masking of speech and traffic
- Pink noise — softer, more like a waterfall; many people find it less fatiguing
- Brown noise — deeper, surf-like, useful when you want a low rumble more than a hiss
- Nature — wind, wave, fan, fire
White vs Pink vs Brown vs Rain
The four sound similar at a glance, but they are not interchangeable:
| Sound | Spectral shape | Best for |
|---|---|---|
| White | Flat across frequencies | Masking sharp speech (TV, neighbors) |
| Pink | High end rolled off | General sleep, less fatiguing |
| Brown | Rolled off harder again | Deep, low-bias mask |
| Rain | Pink-like, more variable | Most people's "easiest to fall asleep to" |
If a sound feels grating after ten minutes, try moving one step toward brown.
Setting It Up
- Open White Noise Sleep Sounds.
- Pick a preset. Most people start with rain or pink noise.
- Set the timer to 30 or 45 minutes. Tap fade-out.
- Drop the phone face-down on the nightstand.
That is the whole setup. No account, no sign-in, no nag screens.
Pricing
Free. There is a Pro tier that unlocks additional preset packs and longer mix options, but the base app — including the sleep timer — is free and ad-free.
Try It
Get [White Noise Sleep Sounds on the App Store](https://apps.apple.com/us/app/white-noise-sleep-sounds-baby/id6740737671). The first night, pick rain, set a 30-minute timer, and see whether you wake at the same time as usual or earlier — that is the most honest signal about whether ambient audio helps your sleep specifically.
よくある質問
Why use a sleep timer at all — won't it just stop playing if I'm asleep?
Continuous broadband noise across the full night can suppress REM and reduce overnight learning consolidation. A 30–60 minute fade gives you the falling-asleep benefit without the all-night cost.
White, pink, brown — what's the difference?
White noise has equal energy at every frequency (hissier). Pink noise rolls off the high end (softer, more like a waterfall). Brown noise rolls off harder again (deep, more like surf). Rain is closer to pink in spectral shape.
Does it work with Apple Watch?
The app runs on iOS, iPadOS, macOS, and visionOS. Watch playback is not the primary use case; the typical setup is iPhone next to the bed with the timer on.
