Do Binaural Beats Really Affect Brainwaves?
- JohnTHaller 11y agoTL;DR: No, they do not.
- leeoniya 11y agoalso follows from [1] [1] https://en.wikipedia.org/wiki/Betteridge's_law_of_headlines https://en.wikipedia.org/wiki/Betteridge's_law_of_headlines
- yathern 11y agoI think that 'law' is better applied when the headline is trying to catch attention by making an aggressive claim, but wants to not be straight up lying. Here it's genuinely taking a skeptical point of view on binaural beats. For example 'Could this new device give you thirty more years of life?' (no) versus 'Does Elon Musk have intentions of leaving Tesla soon?' (no) (or yes, I don't really know)
- abandonliberty 11y agoYes, that is valid. Yathern's corollary?
- leeoniya 11y agoyeah i guess that's true
- zamalek 11y agoSo the next question is: how would you do this (e.g. electrodes)? Following that, considering that we now don't actually know what entrainment does (by virtue of never achieving it), what would be the result of brain wave entrainment?
- yaw 11y ago"we've done this experiment on two subjects"

- rosser 11y agoI wouldn't be too eager to draw a definitive conclusion from N=2.
- abandonliberty 11y agoWasn't even single blind. https://en.wikipedia.org/wiki/Blind_experiment https://en.wikipedia.org/wiki/Blind_experiment I'm sure we could at the very least get a strong placebo response with the right participant.
- kennywinker 11y agoHow on earth would you do a blind test of something so perceptible to the senses? You can hear the beating.
- WalterSear 11y agoIt's 2 more than any published study I can find investigating the effects of binaural beats. And I'm pretty certain this is why: http://www.psychfiledrawer.org/TheFiledrawerProblem.php http://www.psychfiledrawer.org/TheFiledrawerProblem.php
- herriojr 11y agoMy wife actually did a study of this a long time ago for her Master's degree after having dealt with EEG Biofeedback training under supervision of an MD for years. She had a bunch more participants. In short, Binaural Beats don't work. edit: I'll see if I can get a link to her paper
- itistoday2 11y agoUm, brainwaves != subjective cognitive effects. Even plain old, ordinary, non-binaural music has significant, meaningful cognitive effects (and is often used in gyms and therapy for that purpose). Most know from first-hand experience that sound can affect the brain (and body) in significant ways. Sound affects neurotransmitters and hormones in the body. If it didn't, we probably wouldn't have ears. The purpose of ears is to make it possible for sound to affect us. If your conclusion is "no effect", you're probably not listening hard enough, or for the right thing. That "Not much difference" could make all the difference.
- derefr 11y agoI think the "binaural beat" literature is focused on the question of whether such beats can affect people without conscious auditory processing—i.e., whether the particular firing pattern the beats create is an effective side-channel attack on the synaptic substrate.
- itistoday2 11y agoWhat is "conscious auditory processing", and what is "an effective side-channel attack on the synaptic substrate"?

- vacri 11y agoThe problem is that EEGs can only measure symptoms, not root causes. They could have obtained exactly the pattern they were after, but still not have achieved their goal cognitive state.
- virmundi 11y agoAs a user of them and isotones, I would like a more comllete attempt. I've got a few isotones from iso-tones.com. The headache mp3 actually helps. The focus ones do too. Perhaps this is just placebo, but with only one data point, myself, I think they can help.
- DiabloD3 11y agoThis study doesn't seem to track the long term use of them, such as doing a study comparing those learning how to meditate vs those learning how to meditate while listening to binaural beats.
- JeremyMorgan 11y agoI use them, got a nice little generator for iPhone that I use almost every day for focus, and relaxing before bed. Could be placebo, could be white noise but either way it works for me.
- Zelphyr 11y agoWhat's the name of the app?
- JeremyMorgan 11y ago"Brainwave" by Bonzai Labs. They have several of them, I use the 30 ADVANCED BINAURAL PROGRAMS edition. Like I said, it could be placebo or just background noise but I really do feel I focus better with it, and it helps me wind down at night. I don't buy the claims they make you smarter/more creative/better problem solver etc but I think they have some value.
- chipuni 11y agoCan the equipment detect differences between brainwaves, outside of binaural beats? Have they run the same tests where they're trying to find the difference between someone resting (i.e. watching television) and someone being very mentally active (i.e. deep programming or whatnot)? That would give an idea of how large the effect should be.
- Omphalosskeptic 11y agoYes, it can. We have used the same OpenBCI board and software in other experiments, and it does show changes — for example, I ran OpenViBE’s demo SSVEP scenario on the same subject, and the spectrogram showed a pattern of increased amplitude that correlated with the target frequencies. Even if the effect was too small to see in the spectrogram, we should have seen some affect in the FFT plot at the target frequency; instead, the amplitude of the trials at the target frequency were very slightly below the amplitude of the control segments.
- hmage 11y agoNo.
- azernik 11y agoHuh. Listening to some samples I'm getting a decent ASMR tingle, which is relaxing and might be what people who listen to these are experiencing. Nothing to support the claims of "Extremely Powerful Third Eye Opening", though. Good lord.
- brobdingnagian 11y agoThis is not a good study. You should create a two-class classifier to differentiate the two sessions rather than just eyeballing it.
- matchagaucho 11y ago5 minutes is too short. It takes about 15 minutes of relaxed meditation for the brain to succumb and sympathize with the frequencies. Checkout the 90 minute videos on YouTube for the full effect.
- im3w1l 11y agoOne method I think I've heard somewhere, is to start the beat frequency at the dominant brain frequency (so 10Hz in this case), and then slowly slide it to the target frequency. Think you could try that too?
- RachelF 11y agoYes, that seems to be the original approach, similar to a PLL design. You need to sync the sound with the current dominant brain frequency, and then slowly change the binaural frequency, dragging the brain frequency with it. Whether this actually happens is open to research.
- photonic29 11y agoIf it dragged dominant EEG frequencies, that would suggest that the effect either alters thalamic pacemaking or otherwise takes over. This audio beat frequency may exist as an analog somewhere locally as changes in average postsynaptic potentials in the auditory cortex, but it would be surprising if the effect grew to a larger sphere of influence. Healthy brains are pretty good at attenuating that kind of insidious network effect.
- charonn0 11y agoProof once again that if the headline is a question the article invariably answers "no".
- deleted 11y ago[deleted]
- pkghost 11y ago5 minutes is just not enough time. Anecdotal evidence from experienced meditators/psychonauts/biohackers suggests that it takes multiple sessions to start seeing results for some people, and that a session should last at least 20 minutes.
- photonic29 11y agoThis study in PLOS seems to agree with the results: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0034789 http://journals.plos.org/plosone/article?id=10.1371/journal.... This study suggests some measurable effects, though not as simple and direct as the appearance of an EEG band at the target frequency: http://www.researchgate.net/publication/239803901_EEG_Coherence_Effects_of_Audio-Visual_Stimulation_(AVS)_at_Dominant_and_Twice_Dominant_Alpha_Frequency http://www.researchgate.net/publication/239803901_EEG_Cohere...
- rhinojosa 11y agoWoah, flashback! It all started with Mega Brain, what almost 20 years ago. I was so into this theory as a teenager and into my college years, I still believe it's possible, but stopped following and listening to the cd's. Glad to see the Monroe Institute still pursuing this science.
- richerlariviere 11y agoI tested it and it worked for me. The main weakness of their analysis is the duration. 5 minutes of binaural waves is not enough.
- desireco42 11y agoThey definitely work for me, I've been using them for years, making them myself. I blame them for profound beneficial effects on myself. From my experience they also worked on others, it takes few listening and effort to allow entrainment as it is subtle effect, but is definitely there. After years of meditating, I made several focus and 'work' tracks that I use. {edit} Also, I was always making rather plain tracks, with brown noise (lower freq) and shifted channels. This is a little different from actual difference in frequency, but to best of my knowledge works the same, also it is way more pleasant to listen to, which is important when you are trying to meditate.
- biot 11y agoI'd be interested in seeing a writeup on how you make them, what settings work for focus vs. work, etc.
- desireco42 11y agoI could go into great detail, and feel free to ping me directly if there are some specifics you are interested, in short for focus, roughly foundation is brown noise, with subtle pings after first 5 mins, in the middle and 3 chimes 5 mins before end. I used... I believe 16-22Hz oscilating entrainment frequency. I have those in 25 and 45 mins, and I used them for Pomidori sessions, hence the chimes.
- thanatropism 11y agoIt'd be very disturbing if something like binaural beats disrupted brain activity at the spatial resolution of EEGs. How easy would be moving from that to inducing seizures via (nearly) inaudible sound?
- rrss1122 11y agoI am wondering the same thing. In fact, I often see a seizure warning with binaural apps. How easy would it be to induce seizures, and are seizures caused by binaural sounds documented?
- michaelochurch 11y agoFive minutes is not enough. It takes 20, at least. You have to be in a quiet environment where you can focus on the sound. Also, I've found better results with isochronic tones. Binaural beats pretty much mandate headphones and, even then, if you're in a noisy environment or there are defects in the headphones that have one side louder than the other, it can be quite "off". It definitely alters consciousness, but I don't know if there's anything magical about beats per se, because drumming has been used to similar effects for thousands of years. Whether it does so by entraining the brainwaves, that I don't know. It seems like a reasonable guess, but the brain is far too complex for one to assume that such a thing as "an alpha state" exists: we actually have multiple frequencies at all times, and variation around the brain, and we're just starting to develop the technical capability to look at the complexity of all this.
- ermintrude 11y agoI use them all the time. I think they're fantastic. They make me so relaxed I almost cannot move. I relax in a very different way compared to when I meditate (with these it's a much more physical deep relaxation, but when meditating I feel a bit more dissociated from my body).
- markeroon 11y agoWhich beats do you use?
