Discover the Hidden White Noise Feature on iPhones

iPhones running on iOS 15 or later have a built-in white noise feature called "background sounds." Users can access this feature by going to Settings > Accessibility > Audio/Visual > Background Sounds. They can choose from a range of sounds and adjust the volume. Additionally, users can set up an accessibility shortcut to quickly turn on and off the background sounds by triple-clicking the iPhone's side power button. While the benefits of sound devices are not extensively researched, they can help block out sudden noises and create a sense of security for better sleep.
