Brain Waves and Esoteric frequencies
Hereunder are the various pulsating low frequency waves generated by our brain, as seen on an EEG (Electro-encephalogram).
It is believed that listening to pulsating low frequencies, with a very low amplitude, can be therapeutic and benefical to our mental health.
Evidently, listening to pulsating low frequencies, with a high amplitude, can be hazardous to the ear and our physical health!
Delta : 0.1 to 3 Hz.
Theta : 3 to 7 Hz.
Alpha : 7 to 13 Hz.
Beta : 13 to 30 Hz.
High Beta : 30 to 500 Hz.
