Thank you for your videos.. they have been very helpful to me. I really respect your channel.

I have recently found what binaural beats are, and I am still exploring.. I have a question: I know that you care about the difference of the frequencies between the two ears, but what are the reasons that make you choose a specific frequency on one ear. Put differently, why 90Hz on left ear (and 98 on the right one, supposedly that we want an 8hz binaural beat) and not 190 hz on the left ear (and 198hz on the right)?
 
Keep up the good work!
Since we read left-to-right in English, the smaller number usually goes on the left... and that's about it. It doesn't actually make any difference if you accidentally have your "L" and "R" earphones switched.
