Sleep sounds are worth trying if a quiet, steady background makes bedtime easier for you. Research hasn't found one sound that works for everyone, and music has the clearest support so far, mostly for how well people feel they slept. If your room is quiet and you sleep well, silence is fine. Otherwise, try one low-volume sound for a few nights and see whether you wake up more rested.
We make StillTune, a sleep and focus app with music, nature sounds, and noise layers, so we have a reason to like bedtime audio. Below, we try to keep what the research shows separate from our own listening advice.
Which sleep sounds are worth trying?
Start with why you want sound at all. A car door slamming outside calls for something different from a room that feels too silent. Or you may simply like music while you wind down.
If you want a soft backdrop, try rain, distant ocean, or wind. A light rain track can fade into the room, while sharp drops on a metal roof may keep asking for attention. Our guide to rain sounds and guide to ocean sounds look at each one separately. We haven't found a fair head-to-head trial showing that one of them works better for sleep.
For outside interruptions, we'd try a steady fan-like sound or a low noise layer. To our ears, birdsong, voices, and sudden thunder are more likely to pull your attention. White, pink, and brown noise differ in how much low and high sound they carry. The color names describe how each one sounds and say nothing about which helps sleep more. Our comparison of white, pink, and brown noise explains the differences.
If music helps you settle, pick something you can leave alone. A favorite song may keep you waiting for the chorus. We'd keep bedtime music quiet and skip tracks that suddenly get louder. Our sleep music page shows the kind of slow, spacious sound we aim for.
What does the research say about sleep sounds?
For music, the strongest evidence we found is a Cochrane review of 13 randomized studies in adults with insomnia or sleep difficulties. Compared with no treatment or usual care, listening to music probably improved how people rated their sleep quality. The evidence on falling asleep faster, sleeping longer, and sleep efficiency was low certainty. The studies used prerecorded music for 25 to 60 minutes a day, so they say little about leaving music on all night.
Noise has a weaker record. A 2025 perspective in the journal Sleep calls the evidence for white, pink, and other broadband noise equivocal. It cites two systematic reviews that found no consistent evidence that noise improves sleep, and it describes results from home-based studies as very inconsistent.
App-based audio has been tested as well. A 2023 pilot trial randomized 300 UK working adults who slept poorly. Those who used a track of ambient music and nature sounds for four weeks reported less sleep disturbance than a waitlist group. The authors list the limits themselves: the control group received nothing, participants knew which group they were in, and sleep was self-reported.
At home, ask whether you want to turn the sound on again, whether you can stop listening to it, and whether you feel okay in the morning.
Can silence be the best choice?
Yes. If your bedroom is quiet and you sleep well, there's little reason to add audio. The National Institutes of Health advises keeping the bedroom quiet, cool, and dark. The same page lists listening to music as a relaxing part of a bedtime routine. You could play music while you get ready for bed and switch it off when the lights go out.
A sound can't remove whatever is making the noise. A low, steady layer may make some interruptions less noticeable, but a neighbor's TV can still cut through. If you can make the room quieter, start there before turning your speaker up. If you share the room, ask your partner whether the sound bothers them.
If you catch yourself following every change in a sound, switch it off. Some listeners enjoy the rise and fall of waves, and others end up waiting for the next crash.
How would we test a sleep sound at home?
Pick one reason for using sound and keep the experiment simple. Try a single sound for a few nights. If your schedule allows it, spend a few nights without it too. Notice whether falling asleep feels easier and whether you wake up rested. Don't change several bedtime habits at once if you want to judge the sound itself.
Start at a level that's easy to ignore. If you need to turn it up to cover loud traffic, look for a way to cut the traffic noise too.
Listen for abrupt edits, ads, loud effects, or a loop you can predict. Change the track if one of those keeps catching your attention.
Try a fade-out timer if you want sound while you settle and quiet later. You can leave a gentle sound on longer if that suits your room and the people in it.
Use a speaker at a comfortable distance if earbuds bother you in bed. If you use headphones, keep the volume low.
Volume matters. The National Institute on Deafness and Other Communication Disorders explains that sounds can damage hearing when they're too loud, even briefly, or when they're both loud and long-lasting. Turning a bedtime track up until it fills the room also defeats the point of a gentle background.
If sleep problems persist, talk with a doctor or sleep specialist. An app can be part of your routine, but it can't tell you why you're sleeping poorly.
Where does StillTune fit?
StillTune lets you mix instrumental music with rain, ocean, wind, thunder, or fire, plus an optional white, pink, or brown noise layer. In the Mixer, you can turn the music down and keep a texture, or leave the weather out entirely. In Sleep mode, the music gets slower and thinner as it goes, and the sleep timer fades the sound out gradually. It's free with ads, and you don't need an account. Try StillTune on the App Store.
Frequently asked questions
What are the best sleep sounds for adults?
Research hasn't identified one sleep sound that suits every adult. If your room is quiet and comfortable, silence works. Otherwise, choose a gentle sound you can stop paying attention to, such as soft instrumental music, rain, or a steady noise layer. Keep the volume low and judge it by how your nights go.
Are sleep sounds better than silence?
Not necessarily. The NIH advises a quiet bedroom, and a 2025 perspective in Sleep calls the evidence for white and pink noise equivocal. Music has better support, mostly for how people rate their sleep. If your room is quiet and you sleep well, silence is a fine choice.
Is music or white noise better for sleep?
We haven't found a direct comparison of the two for adults at home. A Cochrane review found that music probably improves self-rated sleep quality compared with no treatment or usual care, while reviews of white and similar noise found no consistent benefit. Try each one quietly and keep the one you can ignore.
Should sleep sounds play all night?
They don't have to. The music studies in the Cochrane review used sessions of 25 to 60 minutes, and we haven't seen a trial showing that all-night sound works better. A fade-out timer makes sense if you like quiet after you fall asleep. A longer session may suit a room that gets noisy later at night.
Can sleep sounds treat insomnia?
No. Sleep sounds can be part of a pleasant routine, but they aren't a diagnosis or a treatment plan. If you often struggle to fall asleep or stay asleep, talk with a doctor or sleep specialist. Turning the volume up or adding more layers won't tell you what's causing it.
