Pure 40 HZ Binaural Beats: The Frequency for FOCUS, MEMORY, and CONCENTRATION

When two tones of slightly different frequencies
are played in separate ears simultaneously (through headphones),
the human brain perceives the creation of a new, third tone,
which is called Binaural Beats.

According to a 2017 study (Colzato)
40 Hz binaural beat is the most beneficial for enhancing focus
and generating improvement in cognition.

For maximum effect, listen to this for 30 minutes BEFORE working / learning.
