Binaural Beats

A big part of my in depth meditation requires a pair of noise-canceling headphones, YouTube, and about three or more hours of my time. Why? Well, to listen to some music but, not just any type of music.

A big part of my in depth meditation requires a pair of noise-canceling headphones, YouTube, and about three or more hours of my time. Why? Well, to listen to some music but, not just any type of music. No, this type of music does not have any deep or soulful words. It isn’t put out by big name artists, like Katy Perry, Nicki Minaj or Justin Beiber. This type of music is quite simple in it’s form. It requires two independent frequencies, panned hard left and hard right. (Please, forgive me for my sound design jargon.) The frequencies are tuned to within 40Hz of each other. One ear could be hearing a frequency of 1115Hz the other ear could hear a frequency of 1120Hz. The brain will then perceives a third, auditory illusional tone that is not actually produced by either phone. It is this tone that is called a binaural beat. The third tone in this case would be five Hertz which is the difference between the frequencies heard in either ear.
Binaural beats can be used to help people with different mental health issues by coercing the brain to emit brain waves of a similar Hertz. Below is a table with corresponding hertz and states of consciousness.

Type Frequency in Hz Cognitive Description
Delta up to 4 Occurs in sleeping adults and is frequent in babies.
Theta 4 to <8 Common frequency found in young children.
Indicative of drowsiness or arousal in older children and adults.
Alpha 8 to 13 Indicative of a relaxed state.
Beta >13 to 30 Indicative of an alert or focused working state.
Gamma 30 to 100+ Indicative of sensory processing.
