Hi all, I posted this in the other binaural beat thread.
I've been personally involved directly and indirectly with binaural beat soundtracks and technologies since about 1987. The most benefit from them are never the affirmations but are definitely the entrainment frequencies.
Those could be worth their weight in gold just the frequencies alone. I prefer these soundtracks with only the beats but no affirmations so I produce my own and have for years.
The way the technology is, it is difficult to make one binaural beat soundtrack better than another if 2 tracks are trying to achieve the same purpose.
right ear to left brain. left brain to right ear. corpus collosum is traffic director between the hemisphere. 100 in one ear and 107 in the other ear. traffic director cancels them out and there is a "phantom beat of 7hz...difference between the 2 that is created in your own brain and doesn't come from the headphones. your brain then synchs to 7hz. that is exactly what binaural beat brainwave technology is.
This has been known for a couple hundred years almost. One company can't really make a track that gets you to theta for example any better than another. They will use the same basic method but may just use different frequencies. Almost doesn't matter because the difference between the two will be what the brain synchs at anyway.
So one company uses 100/107 or one uses 1000/1007. One better than another? If you can get them to have a different difference between them it is beyond me.
I explain more in this post about it and also about PATHS, light years beyond binaural beat technologies.
