[edit] Another reference

I think this is a good alternative to the commercial crap about Brainwave Synchronization. The helpfile of CoolEdit '96 discribes the principle very simple and clear and also instructs how to make your own soundfiles if you want to 'Sync your Brain'... Arnoldus 23:09, 1 August 2007 (UTC)

[edit] External Link For Simple Overview

Would it be ok to add a link to a site which describes the documented responses within our brains when in certain brain wave patterns. This site has an easy to understand chart and brief and simple explanations of how binaural beats work, how isochronic tones work and how brainwave entrainment is achieved. http://www.relaxmp3.co.uk/brainwave-entrainment/chart.htm many thanks Leelahcat 15:22, 8 July 2007 (UTC)

[edit] Link to Commercial Site

Anyone have an objection to linking to [1], which has an MP3 demonstration of binaural beat frequencies? Grunnah 02:04, 9 January 2007 (UTC)


[edit] Deletion?

Why in the world would this article be deleted? It was nominated for deletion over a year ago and that's still valid? 209.150.56.190

[edit] Health issues?

Noted in the article on binaural beats, risks include seizure and death. Can we get some numbers on how often that happens? Same risk as a Pokemon episode? or are we talking 1 in 10 here.

On http://en.wikipedia.org/wiki/Talk:Hemi-Sync the user Pessia complained of having tinnitus after listening to this. I got it too however only temporarly and for a short time. KhaaL (talk) 02:37, 15 January 2008 (UTC)

[edit] Possible addition

I have been reading here and there about brainwave entrainment. This is how I understand it. Correct me if I am wrong. I don't feel confident adding this information to the article. Maybe someone with more knowledge?

  • The frequency that the brain is entrained is being entrained to is too low for our ears to hear and so two sounds are played at the same time in different ears. If one sound was at 500 hz and the other at 10 hz then they ,.... ok I thought I could recall what I had learned lol. Wow, does anyone understand what I was trying to get at?

[edit] Marked for cleanup?

Marked for cleanup? What does that mean? This is a perfectly fine entry. Additional information wouldn't hurt, but it shouldn't be removed. —The preceding unsigned comment was added by 207.65.59.153 (talk • contribs) 06:48, 29 January 2006 UTC.

[edit] Sub-bands reference

I've found and added a reference for the sub-bands,[2] at least we are sure they weren't made up by the author of the article. However, this is a page selling commercial products, so it's not the best choice. If someone finds a link to a non-commercial page with the same info, feel free to remove the current one. --Army1987 17:04, 11 April 2006 (UTC)

You've almost got it. If in one ear is a pattern of 500hz and in the other 510hz, then theoretically the brain calculates that as 10hz.

[edit] External links

This article was jam-packed with commercial/advertising links, so I reduced it to the only non-commercial link I saw. Please discuss links here first before adding them to the article. Thanks --AbsolutDan (talk) 02:42, 5 July 2006 (UTC)

[edit] overview

not to be an ass, but am i the only one who thinks the overview sounds like total nonsense? "Brainwave synchronization is a private case of functional brain connectivity concept, whereas functional connectivity is defined as the temporal correlation between spatially-remote neurophysiological events, expressed as deviation from statistical independence (temporal correlation) across these events in distributed neuronal groups and areas, which produce the brainwaves". near as i can tell, functional connectivity means 'two things happen at the same time' which could have been written a lot better. and i have no clue why this is a private case; are there public cases of brain connectivity? this seems like someone took a dense scientific article and ran it through babelfish a few times. --dan 03:56, 12 August 2006 (UTC)

[edit] No criticism?

Something as flakey as this sounds must have some critics. —The preceding unsigned comment was added by Siodine (talk • contribs) 15:18, 21 January 2007 (UTC).

Yeah, I'm curious about it too. I vaguely remember there was a criticism section in the binaural beats article completely debunking it, but it disappeared. Frigo 16:01, 25 April 2007 (UTC)

Nothing "flaky" about Brainwave synchronization except that this article should be called "brainwave entrainment" or "Frequency Following Response", because "Brainwave synchronization" is not the official term I've seen in the literature. BTW, Stanford just held a big symposium on this Brainwave Entrainment -- see external link to: Brainwave Entrainment to External Rhythmic Stimuli - Interdisciplinary research and clinical perspectives symposium

Hello 69.183.0.63. You haven't explained WHY it is not flaky. And by the way, you seem to be eager to spam wikipedia about this symposium. Frigo 00:49, 7 July 2007 (UTC)

It is not flaky, as it's grounded in some solid scientific background. Agreed: Brainwave Entrainment would be good, but Frequency Following Response would be better. Synchronization is factually shoddy, and kinda sounds rather too positive. If that makes sense. Suffice to say, there will always be some significant grey areas when dealing with fringe science such as this.89.241.181.185 23:22, 9 August 2007 (UTC)

[edit] What about centerpointe.com?

Why you mentioned only HemiSync, Immrama, and not Centerpointe Reasearch Institute

[edit] Copying Off I-Doser

"Brainwave synchronization (entrainment) may be achieved when audio signals are introduced to the brain causing a response directly related to the frequency of the signal introduced, called binaural beats. Two tones close in frequency generate a beat frequency at the difference of the frequencies, which is generally subsonic. For example, a 500 Hz tone and 510 Hz tone will produce a subsonic 10 Hz tone, roughly in the middle of the alpha range."

This is lifted directly from the I-Doser website, which I consider to be incredibly unreliable because, A, their main object is to sell you their product, and B, they themselves fail to cite any resources, such as scientific evidence to support their claims. So does this passage merit a delection, a citation, a disclaimer, or what? -71.104.92.253 00:19, 15 May 2007 (UTC)

Deletion as copyvio. Go ahead, fix it. :-) IPSOS (talk) 03:42, 17 May 2007 (UTC)

It's copyright violation alright, but I have to say, it's also scientifically sound, and nicely put. Maybe someone should write something similar, as then it would not be paraphrasing others, because it is pure fact. Sorry to be an ass, but I had to point out that there's nothing SCIENTIFICALLY wrong with the above.89.241.181.185 23:19, 9 August 2007 (UTC)

[edit] Removed link to online shop making false claims

Just look at http://www.mind-optimizer.com/Answers and you understand what i mean. they have testimonials writing things like: "I had been stuck in a low paying office job for over 10 years and thought I'd be stuck there for another 10. Then my wife gave me the Mind-Optimizer Volume 6 CD for "Attracting Money and Wealth". All I did was start listening to it regularly and that was it. Now it's 4 months later and I'M looking for office staff for my own business! I can't believe how this one little CD pulled me out of a 10 year rut in a dead-end job. I can just imagine what the other CDs will do for me." most statements on the page are exaggerated likewise. if it would be that easy to change a boring life, they wouldn't set up boring websites and sell stuff over the internet.

[edit] THIS IS A SEPARATE POST, SORRY. WIKIPEDIA'S EDITING SOFTWARE IS COMPLICATED!

Please forgive/excuse any rule-breaking in this post, as I'm not totally au fait with Wikipedia's posting guidelines, and don't have time to read them.

In short: Brainwave entrainment HAS been scientifically proved, and there is no doubt about that. BUT... at present, the market is dominated by Hemi-Sync, a large company who more than likely make hundreds of thousands out of the crap they sell.

In my opinion, all LINKS to Hemi-Sync be removed, and the obvious bias in their favour be removed. NAturally, they must be left in the main article as their founder conducted significant research into the method of binaural beats etc.

Thanks for reading. Again, apologies If I'm not making a great deal of sense. PS: the reason I say to remove links to Hemi-Sync is purely because I believe SOME of the stuff they sell, and the claims they make, are unfounded and ridiculous. 89.241.181.185 23:15, 9 August 2007 (UTC)

Feel free to back up the claims that it's scientific with some links to made research! KhaaL (talk) 02:40, 15 January 2008 (UTC)

[edit] Yes this article needs help

I have read plenty of clinical literature on this topic. I am out of time now, but someone (maybe me) needs to work on this. It is a legitimate subject, and it requires no commercial hype or links. There is plenty of research. And yes, it should be entrainment, not synchronization. Also, the frequency following response is a specific subcategory of phenomena in this topic and should be included in the topics whithin this article or as a separate one.

I just corrected a key myth in this article. Binaural beats are just one way to achieve entrainment. Pulses (tremelo) are actually more powerful from what I've read. A great deal of verifiable information can be added to this article. The nature of light and sound machines, legitimate theory of the mechanism, clinical uses, how the pulses are produced, what the various frequencies correspond to in terms of states of consciousness, (e.g. trance, sleep, alertness...)

Please just think of it as a work in progress and don't remove it. There is a significant body of non-commercial research. Just look in Pubmed (peer reviewed journals database) and see. Robert A. Yourell —Preceding comment was added at 09:53, 10 January 2008 (UTC)
