[quote="daka"] Also, the equalizer option on my player is not very sophisticated, just gives various presets (rock, jazz, etc) and I choose whichever one is most comfortable to listen to, often the "bass" on since it emphasizes the lower frequencies, which I guess is the goal.[/quote]

Daka,

Does your player have an option to turn the equalizer off all together? That would work.

[quote="Pilot69"]Does your player have an option to turn the equalizer off all together? That would work.[/quote]
If it does, then it's disguised as one of the presets ("normal" maybe?).

I suppose one way to find out would be to port the sound from the player back into my PC and then switch between the various settings while having a graphical equalizer display the real-time output.

[quote="twcjr"]The ramping down from 20Hz to 4 Hz, then staying at 4Hz for as time, then ramping back up to 20 Hz is a good way to start. Like training wheels on a kid’s bike. Eventually the 20 - 4 - -20 sequence becomes 10 - 4 - 10; next the time spent in transition between 10 and 4 gets shorter and shorter and then eventually it is just 4 (no transition is necessary). Finally it is nothing at all (0Hz) as the training wheels come off entirely and you are on your own ( no aids, no devices) with an ability to create a steady vibration state in 2 seconds or less any time you want to day or night under most any environmental conditions you find yourself in.

Most people who try to avoid the training wheels stages by leaping directly to the endgame end up out of the game altogether. Everyone is different -- start at a place and go at a pace that optimizes your learning rate. You may have to do some experimentation over several months to find that place and pace.

Tom, I have a question. How does one know when one can go from 20 - 4 - 20 to 10 - 4 - 10, and then to straight 4 Hz? Is there any guideposts or intermediate signs and/or indicators of your progress you can go by to judge "OK, time to switch to the next stage!"?

Pilot69,

You know it might be time to transition when, after initial success for a week or month or two, you feel that the process you are using is unnecessarily slow, tedious, and inefficient. Then, if shortening the process delivers results that are as good as if not better than your previous experience, the change has probably been a good one. However, if shortening the process delivers results that are NOT as good as your previous experience, the change has probably been too much too soon -- try a smaller change.

I'm not sure where this should be posted, but lest I lose this link, I'm posting here for now.

I have not read this yet, just skimmed it enough to know that it will be very interesting to me, and possibly several others here:

(for those who don't want to follow the link, it's the full text journal article: J Neurophysiol 96: 1927-1938, 2006. "Neuromagnetic Responses to Binaural Beat in Human Cerebral Cortex")

If anyone knows of similar links, please post. I'm particularly interested (for the moment anyway) with the use of EEG (etc) and binaural.
