Does listening to sound actually help you relax or sleep?

In specific ways, yes, though less than the category's marketing suggests. Reviews of continuous noise as a sleep aid find studies on both sides — some reporting better sleep, others reporting disruption — and rate the overall quality of that evidence as very low. Music interventions show more consistent benefits than noise in the same literature. The two best-supported uses are masking unpredictable environmental sound and acting as a conditioned wind-down cue.

Do binaural beats work for sleep?

The mechanism they are supposed to work by is poorly supported. When researchers reviewed fourteen studies testing whether binaural beats actually shift brain activity, eight found results that contradicted the idea, five supported it and one was mixed. If you find them pleasant they are harmless — just do not expect a particular frequency to produce a particular brain state.

Is pink noise better than white noise?

Possibly, though not by enough to be confident. A review of 34 auditory stimulation studies found more positive results for pink noise in raw count, while noting design weaknesses across the whole literature. Pink noise has more energy at lower frequencies, which most people find less harsh. Comfort is a reasonable basis for choosing.

Should sleep sounds play all night or stop after a timer?

All night is usually better if you are using them to mask noise, because silence returning partway through is itself a change your brain can notice. If you are using sound purely as a wind-down cue, a 30 to 60 minute fade is fine. Keep the volume low and avoid earbuds you could sleep on.

Can soundscapes help during the day, not just at night?

Yes, for two different jobs. Steady background sound can mask a distracting environment while you work, and a short guided audio track can serve as a deliberate pause when anxiety is rising. Neither is a treatment, but both are low-cost and have essentially no downside.

Sound works best as two things: a way to mask unpredictable noise, and a cue that tells your body the day is over. Of the options, music and structured nature audio have the most consistent evidence; the strongest review of continuous noise rated the evidence that it improves sleep as very low quality, and the brainwave entrainment that binaural beats are supposed to work by was contradicted by 8 of 14 studies that tested it. None of that makes a soundscape useless — it makes it an adjunct rather than a treatment. Keep it quiet, run it all night if you are masking, put the phone across the room, and give it two weeks before deciding whether it does anything for you.

Can sound actually calm you down?

In specific ways, yes — and it is worth knowing which ways, because the ones that work are not the ones usually advertised.

The most rigorous review of continuous noise as a sleep aid found studies pointing in both directions. Some reported improved sleep; others reported that it disrupted sleep. The authors rated the overall quality of evidence that it helps as very low. A larger review of 34 auditory stimulation studies found some encouraging results but concluded that design weaknesses made firm conclusions difficult.

One pattern does hold across that literature: music and structured audio show more consistent benefits than flat noise does.

So sound does two jobs well, and neither of them is “treating sleeplessness”:

Masking. Covering unpredictable environmental sound — traffic, a neighbour, a snoring partner — so individual noises stop pulling you out of light sleep. This is the strongest justification and a genuinely useful one.
Cueing. If the same sound starts every night at the same point in your routine, it becomes a signal that the day is finished. That is conditioning rather than acoustics, and it works for the same reason a bedtime routine works for a child.

Both are real. Neither is dramatic. A soundscape is an adjunct, and a good one.

Which kinds of sound work best?

	What it sounds like	Evidence
Music / nature audio	Structured, varying — rain, waves, soft instrumental	Most consistent benefits of the group
Pink noise	More energy at low frequencies — like steady rain	More positive results in raw count, weak study quality
Brown noise	Deeper still — distant surf, a waterfall	Very little direct evidence
White noise	Flat across frequencies — hissy, like untuned radio	Mixed; some studies found disruption

Of the colours, pink has slightly more going for it, though the review that found this also flagged the quality problems running through the whole field. Most people find white noise harsh and pink or brown easier to sleep through.

Choose by comfort. The differences between them in the research are smaller than the difference between a sound you find pleasant and one you do not.

One practical point in favour of generated or long-form audio over a short recording: a loop you can hear repeating is itself a predictable event, and predictable events are exactly what can pull you back awake. Longer, varying tracks avoid that. This is the one genuine advantage of a large library over a single file.

Do binaural beats work?

This is the corner of the category with the weakest foundations, so it is worth being specific rather than vague.

Binaural beats play slightly different frequencies into each ear — say 200Hz and 206Hz — on the theory that the brain perceives the 6Hz difference and its electrical activity shifts to match. That shift is called entrainment, and it is the entire premise.

Researchers have reviewed fourteen studies testing exactly that. Eight reported results contradicting the entrainment hypothesis. Five supported it. One was mixed. A 2026 review of music and binaural beat interventions in young adults concluded they can beneficially affect sleep, anxiety and cognition, while noting that heterogeneity in design and small sample sizes limit the certainty of the findings. It included ten trials.

The practical reading. Binaural beats are harmless, and plenty of people find them pleasant and calming — which is a perfectly good reason to use them. But the specific claim that a given frequency produces a given brain state is not something the evidence supports, and any product telling you otherwise is ahead of what is known. They also need headphones to work at all, which is its own problem overnight.

How do you use sound to wind down?

The practical details matter more than which track you pick.

Start it before you are in bed, as part of the wind-down rather than a last resort after twenty minutes of lying awake. The cueing effect only works if the timing is consistent.

Keep it quiet — around the level of a quiet conversation. Loud enough to mask, quiet enough to ignore. If you can describe what you are hearing, it is too loud.

Run it all night, if you are masking. A timer that cuts out at 2am restores silence partway through, and the return of silence is itself a change. If you are using sound purely as a cue, a 30 to 60 minute fade is fine.

Use a speaker, not earbuds. Sleeping on earbuds is uncomfortable, can irritate the ear canal, and means you cannot hear a smoke alarm.

Avoid words and structure. Podcasts, audiobooks and lyrics invite attention, which is the opposite of what you want. The point is sound you can stop listening to.

Put the phone across the room. The one most people skip, and it undoes most of the benefit — a phone on the pillow is a notification machine and a 3am reading device.

Can soundscapes help during the day?

Yes, for two jobs that are different from the night-time one.

Masking a distracting environment. Steady background sound while you work does the same thing it does at night: it covers unpredictable noise so individual sounds stop grabbing your attention. For this, something without structure is better — structure is interesting, and interesting is distracting.

As a deliberate pause. A short guided track — a few minutes of breathing or a body scan — is useful mainly because it is a decision to stop, with a defined end. It is not doing anything mysterious to your nervous system; it is giving you a reason to put something down for four minutes, which is otherwise surprisingly hard to justify to yourself.

Neither is a treatment. Both cost nothing and have essentially no downside.

What works better than sound?

Worth knowing where this sits, because nothing on this page is near the top of the list.

For persistent insomnia, the first-line treatment is CBT-I — cognitive behavioural therapy for insomnia — not medication and certainly not audio. It is a structured programme covering sleep restriction, stimulus control and the thinking that keeps the cycle going, with substantially better evidence than anything described above.

Below that, the unglamorous basics outperform any soundscape: a consistent wake time, morning light, a caffeine cut-off, and getting out of bed when you have been awake twenty minutes rather than lying there.

What is in the Moodify library?

We built a soundscape library into Moodify, and the honest description of it is this.

What is in it: sleep sounds and long nature audio for masking, soft instrumental tracks, guided meditations and breathing exercises for the deliberate-pause job, and binaural beat tracks for people who like them.

It is free, and it stays free. That is a deliberate decision rather than a trial period. The audio someone reaches for at 2am should not be behind a paywall, and it will not be behind ours.

What we claim for it: that it is pleasant, that it runs long enough not to loop audibly, and that it is there at the hour you need it. That it masks noise and works as a wind-down cue — the two things the evidence actually supports.

What we do not claim: that it treats insomnia, that any particular frequency does anything specific to your brainwaves, or that it is a substitute for CBT-I. The binaural tracks are in the library because people find them calming, not because we think the Hz is doing the work.

If your sleep has been bad for months, the most useful thing this page can do is point you towards CBT-I rather than towards our own library.

When is sound the wrong answer?

If what is keeping you awake is a thought, not a noise. Audio masks external sound; it does not mask a circling worry. That is a different problem with different answers.
If you have become unable to sleep without it. Dependence on one specific condition makes sleeping anywhere else harder.
If you are using it to stay up. Putting something on while you keep scrolling is not a wind-down.
If sleeplessness has lasted months, or you are exhausted during the day — talk to a doctor and ask specifically about CBT-I.

How to find out whether it is working for you: log sleep quality for two weeks with it and two weeks without. That comparison takes a month and tells you more than any review can, because it is about you rather than about an average. A notebook does it; so does Moodify, which keeps sleep next to mood on one chart.
