Apple quietly tucked a surprisingly powerful feature into iOS that can save you the cost of a dedicated white-noise machine. Background Sounds—originally launched in iOS 15 (2021) and expanded in iOS 18—lets your iPhone stream high-quality ambient audio on a loop, masking distractions, calming anxious minds, and even helping babies drift off to sleep. Here’s everything you need to know to turn the feature on, customize it, and integrate it with the rest of your daily routine.
Why Background Sounds Matter
-
Scientifically backed: Research published by the U.S. National Academy of Sciences shows natural soundscapes (rain, ocean waves, streams) measurably lower heart-rate variability and perceived pain while boosting positive mood.
-
Better focus & learning: Multiple studies have found that steady-state “white-noise–like” signals improve word recognition in infants and help adults stay on task in distracting environments.
-
Zero extra hardware: Your iPhone’s speakers (or any connected AirPods, headphones, or Bluetooth speakers) handle the playback—free, portable, and always with you.
What’s New in iOS 18
| Release | Natural Sound Loops | Noise Loops |
|---|---|---|
| iOS 15 | Rain, Stream, Ocean | Bright Noise, Balanced Noise, Dark Noise |
| iOS 18 | + Night, + Fire | (unchanged) |
Night layers light crickets and distant owls over a still evening backdrop, while Fire crackles gently like a campfire—perfect for cozy reading or bedtime routines.
How to Turn On Background Sounds
-
Open Settings → Accessibility.

Under Hearing, tap Audio & Visual → Background Sounds.

Toggle Background Sounds On (the iPhone will download the selected loop the first time).
-
Tap Sound to choose Rain, Ocean, Night, Fire, and more.
-
Adjust Volume to balance with other media.
-
Fine-tune behavior:
-
Use When Playing Media – Layer ambience under music, podcasts, YouTube, Netflix, etc.

Stop Sounds When Locked – Disable if you want continuous playback after the screen goes dark.
-
Pro Tip: Ask Siri “Turn on Background Sounds” or “Play Rain sounds” for hands-free control.
Add Quick Access in Control Center

Settings → Control Center → + next to Hearing.
-
Swipe down from the top-right (Face ID phones) or up from the bottom (Home-button phones) to open Control Center.
-
Tap the Ear icon → Background Sounds (music-note symbol) to toggle instantly or long-press to switch loops and adjust volume.

Now triple-press the Side button (or Home button) to start/stop playback.
Usage Ideas & Best Practices
| Scenario | Recommended Sound | Tips |
|---|---|---|
| Sleep training infants | Balanced Noise | Place iPhone across the room; keep volume ≤ 50 dB to protect hearing. |
| Deep work / study sessions | Bright Noise or Rain | Pair with Focus Mode; add “Stop Sounds When Locked” so it ends automatically in breaks. |
| Anxiety & mindfulness | Ocean or Night | Combine with Apple’s Mindfulness app or breathing exercises. |
| Tinnitus masking | Balanced Noise | Fine-tune volume so the noise blends with (but doesn’t overpower) the ringing. |
| Storytime ambiance | Fire | Stream through a smart speaker for room-filling warmth. |
Troubleshooting
-
No sound after enabling: Check that Silent Mode isn’t engaged, and verify volume in both Background Sounds settings and Control Center.
-
Battery drain: Streaming audio loops is lightweight, but if you’re noticing heavy usage, disable Use When Playing Media and lower volume.
-
Can’t download loops: Confirm Wi-Fi or cellular data is on; each loop is ~10–15 MB once.
The Bottom Line
Background Sounds transforms any iPhone running iOS 15 or later into a full-featured white-noise machine—no extra gadgets required. Whether you’re calming a fussy toddler, powering through exam prep, or simply unwinding after a long day, these built-in loops can make a measurable difference in stress, focus, and sleep quality. Give them a try and see which soundscape works best for you.
