'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services.

There are plenty of apps available to iPhone users that can play white noise such as crashing waves or a gentle rain, but did you know there's a white noise tool built directly into your iPhone? The lesser known background sounds feature is buried in the Accessibility section of your iPhone, and offers up several different sounds.
How to turn on your iPhone's hidden Background Noise feature
Turning on your iPhone's background noise feature takes just a few taps on your phone's screen. You'll need to have an iPhone running iOS 15 or newer -- no other special equipment is required.
Step one: Open the Settings app
Find and open the Settings app on your iPhone.
Step two: Tap on Accessibility from the list of options
Scroll down until you find Accessibility and tap on it.
Step three: Select Audio/Visual
You'll have to scroll down a bit before you find the Audio/Visual option.
Step four: Tap on Background Sounds
Slide the switch next to Background Sounds to the On position to immediately start playing the default rain sound. You can select the type of sound you want to hear by selecting the Sound option, which will prompt your iPhone to download it on demand. You can also adjust the volume -- which is set independently of your iPhone's ring and music volume.
There's also an option here to continue playing the background sound even when you're watching a video or listening to music.
At the bottom is a toggle that will tell your iPhone to stop playing background sounds as soon as your iPhone locks.
Is there any way to put the iPhone's background sounds on a timer?
You probably noticed in the Settings app there isn't an option to play the sound for a set amount of time. Instead, your chosen sound will continue to play until you you manually stop it. That is, unless, you turn on the option to stop playing the sound when your phone locks.
So, if you want to listen to background sounds for a set amount of time, what do you do? Well, one workaround is to use your iPhone's auto-lock feature as a makeshift timer.
Go back to the Settings app and then select Display & Brightness then select Auto-Lock. You'll have options ranging from 30 seconds up to 5 minutes.
The options don't offer the longest amount of time, and it may not be enough to help you fall asleep -- but it's better than having the background noise play all night; unless, of course, that's what you prefer.
Is there an easier way to access and manage background sounds?
You don't have to dive deep into the Settings app each time you want to control your background sounds. Instead, use Control Center by swiping down from the top-right corner of your screen and then tap on the hearing icon (it's the one with the ear on it).
You can then play or pause, switch between the various sounds and control the volume of your background sounds via the small popup. Much easier.
