Brainwave entrainment is a fascinating concept that involves the use of binaural audio inputs, to synchronize brainwaves and induce specific mental states. This technique leverages the brain’s natural tendency to sync up with external stimuli, such as sound frequencies.
Binaural beats occur when two slightly different frequencies are presented separately to each ear. The brain perceives a third, ‘phantom’ frequency, which is the mathematical difference between the two. This perceived frequency corresponds to a specific brainwave state.
Here are some common brainwave states and their associated frequencies:

1. Delta (0.5-4 Hz): Associated with deep sleep and relaxation.
2. Theta (4-8 Hz): Linked to deep meditation and creative thinking.
3. Alpha (8-14 Hz): Promotes relaxation and a calm, alert state.
4. Beta (14-30 Hz): Connected to alertness and active thinking.
5. Gamma (30-40 Hz and above): Linked to heightened cognitive functions and perception.

By using binaural beats, individuals aim to entrain their brainwaves to a desired frequency, thus encouraging a specific mental state. For example, someone looking to relax might listen to binaural beats in the theta or alpha range.
