| Sep 7, 2016 at 22:22 | comment | added | TheBlackCat | Binaural beats are derived from interaural time differences (ITDs). We can't detect ITDs more than about 30 ms, which is equivalent to a binaural beat of about 33 Hz. We also can't detect ITDs with frequencies more than about 1000 Hz due to how neurons encode sound. So the limits of binaural beat processing are really the limits of ITD processing. And ITD processing is a pretty low-level (brainstem) activity, not cortical. | |

| Jun 29, 2015 at 15:08 | comment | added | Christian Hummeluhr | Binaural beats are not substantially different from optical illusions, in my view. No one would expect staring at a vase-face illusion for an hour a day to bring cognitive benefits. Why would we expect BBs to have applications outside of things like artistic expression? (Mostly responding to allusions made to this 'following in line with research' by various companies marketing to consumers here.) | |

| Jun 23, 2015 at 20:09 | comment | added | draks ... | @Krysta I added a more recent reference...and I also agree with all your comments on the paper, but it's still interesting to read... | |

| Jun 23, 2015 at 11:43 | comment | added | Krysta | It's also worth noting that this paper doesn't compare the effects of binaural beats on any particular variable at a higher level than an evoked potential to that of non-binaural beats, nor does it attempt to correlate the change in evoked potential to any particular experiential or higher-level variable. That's really the level of experimentation that would be required to establish that BB does anything other than make a different sound. | |
| Jun 23, 2015 at 11:40 | comment | added | Krysta | Since you've asked, I'll say this seems like fairly early-stage research to me; as far as I understand it, the question it's answering is whether and what binaural beats can be perceived, and not whether they have any effects on cognition/mood/etc. Similarly, using them as a diagnostic tool would require significant validation not done here--that seems entirely speculative (or possibly anecdotal). So although this is a good description of what binaural beats are, it doesn't present any evidence for any application. | |
