A 2026 clinical trial found that 24 minutes of music with auditory beat stimulation (ABS) reduced anxiety in medicated adults more than pink noise did.
How long do you need to listen to beat-embedded music before anxiety drops?
Your go-to calming playlist might be doing more than setting a mood. Depending on what’s layered into the audio, it could be shifting your brain toward a less anxious state. And the amount of time you spend listening turns out to matter more than you’d expect.
A clinical trial published in January 2026 tested whether there’s a dose-response relationship between listening time and anxiety relief when music is combined with a technique called auditory beat stimulation, or ABS. The answer:
“Yes, and 24 minutes appears to be the threshold where things click into gear.”
What auditory beat stimulation does to your brain
ABS is a broad category that includes binaural beats, one of the more popular forms. The core mechanism is easy to grasp. When two tones of slightly different frequencies reach your ears separately (say, 200 Hz in the left ear and 206 Hz in the right), your brain perceives a third tone pulsing at the difference between them. That’s 6 Hz, which falls in the theta frequency range of 4 to 7 Hz.
Theta waves are the brain’s signature pattern during deep relaxation, meditation and the early stages of sleep. The theory behind ABS is that this perceived third frequency can coax your brainwaves to synchronize with it, a process researchers call brainwave entrainment. Your neural activity starts to mirror the rhythm of the stimulus.
This isn’t a fringe idea. A 2019 meta-analysis in Madrid analyzed 22 studies on binaural beats and found a medium effect size across outcomes including anxiety reduction, cognitive performance and pain perception. Longer exposure times produced stronger effects. Sessions in the 20- to 30-minute range consistently outperformed shorter ones.
The trial
The 2026 study recruited 144 adults with moderate trait anxiety. All participants were already taking medication for their symptoms.
Researchers randomly assigned participants to one of four groups. The control group listened to 24 minutes of pink noise (a steady background hum similar to white noise). The three experimental groups listened to calming instrumental music embedded with theta-range ABS for 12, 24 or 36 minutes.
All 3 ABS groups beat the control
Every music-with-ABS group showed larger reductions in both cognitive and somatic anxiety than the pink noise group. The 24-minute group produced the most consistent improvement. The 36-minute group showed similar gains but didn’t surpass the 24-minute group. The 12-minute group still outperformed the control, though with a smaller effect.
“What we’re seeing is that 24 minutes of music with ABS seems to be the sweet spot.”
359 million people with anxiety
The World Health Organization estimates that 359 million people worldwide had an anxiety disorder in 2021, making it the most common mental health condition on the planet. The treatment gap is staggering: only about 1 in 4 people who need anxiety treatment receive any, according to WHO data. Cost, waitlists, limited therapist availability, and medication side effects all stand in the way.
Sound-based interventions won’t replace therapy or medication for people with clinical anxiety. But they fill a gap. Free (or nearly so), no appointment needed, no side effects, accessible from a phone. For someone sitting on an 8-week waitlist for cognitive behavioral therapy, or dealing with the adjustment period of a new medication, a 24-minute listening session is a low-risk option that now has randomized trial data behind it.
The researchers position ABS music as a complement to existing care. Mullen noted in the study that the findings could help people who don’t yet have access to traditional treatment, as well as those in the gap between starting a new treatment and that treatment taking full effect.
How to try it yourself
Binaural beats playlists are widely available on Spotify, Apple Music, YouTube, and other streaming platforms. Spotify’s “Binaural beats 4-8Hz” playlist is one popular option. You’ll also find playlists specifically designed for focus, relaxation and sleep that incorporate theta-range frequencies.
What to keep in mind
You need headphones. That part is non-negotiable. The entire mechanism of binaural beats depends on delivering a different frequency to each ear, and speakers blend the sound before it reaches you. Over-ear headphones tend to work best for sessions this long because in-ear buds can get uncomfortable after 20 minutes.
Look for playlists that specify theta frequencies (4 to 7 Hz). Some binaural beats playlists target different frequency bands for alertness or focus, which aren’t what this research supports for anxiety.
Don’t stress about hitting exactly 24 minutes. The meta-analysis found the effective window falls broadly between 20 and 30 minutes, so anything in that range should work. Set a timer if it helps, or pick a playlist that runs about that length.
Close your eyes if you can. Both studies asked participants to do this during their sessions, likely because shutting down visual input deepens the relaxation response.
What the science still needs to sort out
The evidence for ABS and anxiety is growing. It’s also not settled. A 2023 systematic review examined whether binaural beats produce reliable changes in brainwave activity and found mixed results. Some studies showed clear EEG shifts; others didn’t. The anxiety-reducing effects observed in behavioral studies might work through mechanisms beyond simple entrainment, including distraction, the relaxation response, or plain old expectation.
Both the 2022 and 2026 studies were partially funded by LUCID, the company that developed the music curation system used in the research. This doesn’t invalidate the results (the studies were peer-reviewed, pre-registered, and published in reputable journals), but keep it in mind when evaluating the evidence.
The participants all had moderate trait anxiety and were already on medication. Whether the same results hold for people with severe anxiety, or those not taking any medication, remains open. Larger trials across more varied populations would strengthen the case.
Slutresultatet
A 24-minute listening session with the right kind of embedded audio isn’t going to cure an anxiety disorder. But it could take the edge off a rough afternoon or calm your nervous system before a stressful meeting.
The barrier to trying it is about as low as it gets: a pair of headphones and a free streaming playlist. If you’re already managing anxiety through other channels, this is one of those rare interventions where the potential benefit outweighs the cost of trying.
Frequently asked questions (FAQ)
What are binaural beats and how do they reduce anxiety?
Binaural beats are an auditory phenomenon that occurs when two tones of slightly different frequencies are played separately into each ear. Your brain perceives a third tone at the difference between them. When that difference falls in the theta range (4-7 Hz), it can encourage your brainwaves to shift toward patterns associated with relaxation.
How long should I listen to binaural beats for anxiety?
About 24 minutes. A 2026 clinical trial tested 12-, 24-, and 36-minute sessions and found that 24 minutes produced the strongest anxiety reduction. The 36-minute group saw similar gains, so anywhere from 20 to 30 minutes is a reasonable target.
Do I need headphones for binaural beats to work?
Yes. Binaural beats depend on delivering a different frequency to each ear. Speakers blend the audio before it reaches you, which eliminates the frequency difference. Over-ear headphones are the most comfortable option for sessions of this length.
Can binaural beats replace anxiety medication or therapy?
No. The researchers behind these trials position ABS-based music as a complement to existing treatments, not a replacement. It may be useful for people waiting to start therapy, adjusting to new medication, or looking for an additional tool alongside their current treatment.
What is auditory beat stimulation (ABS)?
ABS is a category of sound-based techniques designed to influence brain activity. It includes binaural beats (different frequencies in each ear) and monaural beats (combined before reaching the ear). The clinical trials discussed here used theta-range ABS embedded in calming instrumental music.
Is there strong scientific evidence for binaural beats?
The evidence is promising but still developing. A 2019 meta-analysis of 22 studies found a medium effect size (g = 0.45) for binaural beats across anxiety, cognition, and pain outcomes. Two randomized clinical trials (2022 and 2026) both found that music with ABS reduced anxiety more than pink noise. But the brainwave entrainment mechanism itself has mixed support in EEG studies.
