Simply put, binaural beats are two sound waves with differing frequencies placed on each ear separately. The difference of the frequencies results in a number. For example, if one wave is 40 Hz and the other wave is 47 Hz, and both waves are played through headphones (one wave for each ear), the result is a 7Hz wave moving through the brain.

As the brain is exposed to the sound waves, it becomes entrained and moves into that wave frequency. There are measurable brain waves that create distinct states of mind, therefore, as the brainwaves shift to the introduced wave frequency,  the state of mind is altered. 

The term hertz, or Hz, is a way to measure waves in terms of cycles per second. That is, how many wavelengths occur in one second.

When you are listening to pure binaural beats that are easy to hear and feel. When they are mixed in with music it may be difficult to hear separate them out with your ears but easier to feel them.

According to studies, peak athletic and general peak performance happens in what is referred to as a Flow State. The brain waves in these states have been measured around 7.5Hz, roughly in between Alpha and Theta waves. The TU album uses this frequency most to induce this state. The intention of the music is to bring the listener's mind into a flow state for numerous benefits, including but not limited to athletic performance, relaxed yet fluid like awareness, clarity of thought, creativity, ease os stress
