Binaural beats are created when two tones of different frequencies are played separately into each ear through headphones, leading the brain to perceive a third tone—the binaural beat. The binaural beat is the difference between the two frequencies. Binaural beats work through a process called brainwave entrainment, also known as neural entrainment, Paul Citarella, executive vice president and chief technical officer of the Monroe Institute, told The Epoch Times.
He said that brainwave entrainment is “presenting some kind of rhythmic stimulus to your brain, and your brainwaves start to follow along.” A simple example is a beating drum. “If someone’s beating a drum, let’s say six times a second, what happens is, that sound is reaching your ears six times a second, and your brain—your neurons in your auditory cortex—are firing to receive that sound, or in response to that sound,“ Citarella said.
”And what happens is as you listen to that over time, the rest of your brain waves start to follow along to that rhythm,” he added. Other examples include rhythmic chanting, and drumming that go back to spiritual traditions through the ages, he said. Delta (0.
