Hi Theerapun
For superlearning try a session that goes up and down between 8hz and 10hz, you could also try mixing a 8hz wave with a 40Hz High Beta wave for high cognition while in a relaxed alpha state at the same time. Don't try the 40Hz on it's own, it could be dangerous.
For doing other things at the same time the frequencies between 8 and 13 are good too. This is alpha where learning and other benefits occur. That's what is good about Binaural Beats, you can listen with your ears but still work with your eyes open. There are benefits to listening with eyes closed and open. Closed-stronger entrainment. Open-great productivity and a new experience of the world that you don't normally have when you are in beta.
Good luck.
