A binaural beats is an auditory illusion perceived when two different pure-tone sine waves, both with frequencies lower than 1500 Hz, with less than a 40 Hz difference between them, are presented to a listener dichotically (one through each ear).For example, if a 530 Hz pure tone is presented to a subject's right ear, while a 520 Hz pure tone is presented to the subject's left ear, the listener will perceive the auditory illusion of a third tone, in addition to the two pure-tones presented to each ear. The third sound is called a binaural beat.

Binaural beats is used by people all over the world as a form of ‘brainwave entrainment’ – a process used to entrain the brain into different states that contribute positively to well-being and personal-development.

It is important to know that all humans display five different types of electrical patterns or “brain waves” across the cortex. The brain waves can be observed with an EEG (or an “electroencephalograph”) – a tool that allows researchers to note brain wave patterns. Each brain wave has a purpose and helps serve us in optimal mental functioning.

alpha(α) wave:Relaxation
beta(β) wave: Conscious focus, memory, problem solving
gamma(γ) wave: Binding senses, cognition, information processing, learning, perception, REM sleep
theta(θ) wave: Creativity, emotional connection, intuition, relaxation, meditation
delta(δ) wave: Immune system, natural healing, restorative / deep sleep

To experience the binaural beats perception, it is best to listen to with headphones on moderate to weak volume – the sound should be easily heard, but not loud. Note that the sound appears to pulsate only when heard through both earphones.
