Are binaural beats safe?
For most people this is recorded audio played through headphones, and the things worth being careful about are the things worth being careful about with any headphone audio: how loud it is, how long it runs, and what you are doing while it plays. There are two narrower cautions that deserve to be stated plainly rather than buried, and they are below.
What this page will not do is give you a reassuring number. Nobody has run a safety study of binaural beats; the research that exists asked whether they do anything useful, not whether they do anything harmful, and it is mixed and mostly small-sample. Our evidence page sets that literature out with samples and stated limitations. The absence of reported harm in small studies of a few dozen people is weak evidence of safety, and it is honest to say so.
Volume and hearing: the caution that actually applies to everyone
This is the real one, and it has nothing to do with binaural beats specifically. Sustained headphone listening is a hearing-exposure question, and the exposure depends on both level and duration.
The World Health Organization's safe listening guidance describes a sound level of 80 dB as safe for up to 40 hours a week, and notes that the safe listening time falls to about four hours a week at 90 dB. The same guidance uses a lower reference level for children and other listeners sensitive to intense sound. Those are figures about audio exposure in general; they are not a finding about this genre.
The practical version is short: binaural tracks invite long sessions, so keep them quiet. A steady low tone is easy to creep upward on because it is undramatic, and low frequencies at high volume are still loud. If you use these tracks for hours, the volume setting matters more than anything else on this page. How to listen to binaural beats covers the everyday version of this — where to set the level and how to bound a session.
Epilepsy and audio entrainment
This caution is genuine and it is routinely either omitted or overstated, so here it is with the reasoning attached.
For a small number of people, seizures are provoked by a specific stimulus rather than occurring unpredictably — these are the reflex epilepsies. The best-documented trigger is visual: flashing lights and certain patterns, in photosensitive epilepsy. Sound is also a recognised trigger in some people, including musicogenic epilepsy, where particular music brings on a seizure. The Epilepsy Foundation's account of the reflex epilepsies lists sounds among the environmental triggers and states that simple sound-induced seizures in humans are very rare.
Where does that leave binaural beats? Honestly: unstudied. We are not aware of research designed to test whether binaural beats can provoke seizure activity, and none of the studies summarised on our evidence page was designed to answer a safety question. The caution that circulates about audio entrainment is carried across from the visual case, where the evidence is strong, to the auditory case, where it has not been established either way. That is a reasonable precaution to take and a poor thing to describe as a known risk — and it is equally poor to describe the silence as proof that there is nothing to think about.
So the plain line: if you have epilepsy, have had a seizure, or have been told that sound or music is a trigger for you, ask the clinician who manages your care before adding rhythmic audio of any kind to your routine. That is a decision for someone who knows your history. It is not one this page can make, and nothing here is a judgement about whether any of this applies to you.
What you are doing while it plays
Headphones cover the sounds you rely on, and audio chosen to be absorbing is audio designed to hold your attention. Both matter more than usual here, because these tracks are used precisely when someone wants to stop noticing their surroundings.
- Not while driving, cycling or crossing roads. The point of the audio is to make the environment less salient. That is the wrong goal in traffic.
- Not while operating machinery or anything with a moving part you are meant to hear.
- Consider who else is relying on you to hear something — a doorbell, a child in another room, a colleague. Sound isolation does not distinguish between noise you wanted removed and a sound you needed.
Ordinary discomfort, and what to do about it
Some people find sustained low tones unpleasant, and a small number report feeling tense, headachy or slightly disoriented during or after a session. That is worth taking at face value rather than working around.
If a track is uncomfortable, stop it. There is nothing to push through toward: no dose has been established for this audio, so there is no threshold you are failing to reach and no benefit waiting on the far side of an unpleasant session. Try a lower volume, a shorter session or a different track another time — and if a particular kind of audio is reliably unpleasant, the ordinary conclusion is that it is not for you.
If your ears feel dull or ringing after listening, that is a volume-and-duration signal, and the section above is the response.
If your ears or your hearing are already a consideration
If you have tinnitus, sound sensitivity, an ear condition, hearing loss, or hearing devices, sustained tone-based audio is a reasonable thing to raise with the clinician or audiologist who looks after your hearing before making it a habit. Steady tones are exactly the kind of sound some people find their tinnitus more noticeable against, and that is individual enough that a general page should not guess at it.
What binaural beats are not
Binaura offers soundscapes and breathing exercises. It is not medical care, it makes no health claim, and it is not a substitute for advice from a clinician or for anything a clinician has asked you to do. It does not diagnose anything, and the app does not measure you — the frequency settings described in how to use the app are audio settings, not readings taken from you.
If sleep or anxiety problems keep happening or interfere with daily life, talk with a licensed clinician.
The short version
- Keep the volume low, especially for long sessions — this is the caution that applies to nearly everyone.
- If you have epilepsy or a seizure history, ask the clinician who manages your care first.
- Do not wear headphones where you need to hear your surroundings.
- If it is unpleasant, stop; there is no dose to reach.
- Raise existing ear or hearing conditions with the person who looks after them.
