How Do Binaural Beats Change Brainwave Frequencies?
When the brain is stimulated by listening to a binaural beat there are actually two sound waves of different frequencies present, one being heard through the right ear, and the other through the left. So if ( for example) the right ear is presented with a steady tone of 310hz and the left ear 300hz the two tones combine in the brain and the brain perceives a difference of 10hz. This is the binaural beat. Now, let us assume when we begin listening to this binaural beat our brainwave frequency is between 12hz 38hz (this is commonly known as the Beta brainwave state, a highly alert and often stress related state) by listening to the binaural beat and perceiving the 10hz discrepancy between our right and left ears, the brain will be entrained to enter a 10hz brainwave frequency ( the Alpha brainwave state, a deeply relaxed state, the realm of the creative mind, and platform for higher levels of consciousness). This is known as brain entrainment and binaural beats can be used to entrain the
