The most popular frequency that the majority of people function within is the beta range; this is where the brain waves jump around while you are awake. Although the beta range of brain waves is a wide range, it has been found in extensive studies that using the binaural beats of 20 Hz effectively forces the brain waves into a state where you are focused. 

Binaural beats at 20 Hz cause the brain waves to join into this one frequency which in turn makes you, the listener, focused,  increasing your concentration and your ability to absorb information. People who are studying or have a lot of projects that they need to attend to benefit from the use of binaural beats at 20 Hz, some people who have successfully used binaural beats to assist them with focusing on a particular project have noticed other effects like ‘time seems to stand still’.  Some participants in various studies felt like they were hard at work for 30 minutes or longer, only to realize that 5 or 10 minutes had passed instead. 

Binaural beats are not suitable for everyone and as with most types of therapy there are individuals who do not experience any effects from binaural beat therapy.  It is also important to remember that anyone who has epilepsy or any other form of mental disability should not enter into binaural beat therapy as it is can make an existing disability worse.
