Binaural beats study and learning12/30/2023 ![]() The binaural pulse is actually a mental illusion and state of mind and not a real auditory sound being heard by your ears. When you put on a set of headphones and listen to a binaural beat soundtrack, the two separate tones delivered to your ears become one beat frequency inside the auditory center in your mid-brain, resulting in a third, pulsing tone which is the actual binaural beat. Hz is merely an abbreviation for the word hertz, a unit of measurement of electrical vibration measured in oscillations per second. These separate tones are known as the carrier frequencies or carrier tones.įor the binaural tone to be perceived in the mind, the carrier tones must be of the same amplitude and differ from one another by approximately 40 Hz or less in frequency. This research continues to this day.īinaural literally means “two ears,” and this refers to the fact that binaural pulses involve separate tones heard by each ear. Oster published his findings in a paper in the science journal Scientific American, leading to an avalanche of further research and discoveries on the neuroscience of how listening to binaural tones can affect the mind, mood, and behavior of human beings. Oster explored the nature and uses of binaural sounds, discovering that when the difference in frequency between the two tones is in the range of human brain waves, the listener’s brain waves synchronize with this frequency in a process known as brain wave entrainment. In 1973, an American psychology researcher named Gerald Oster rekindled Dove’s discovery and took it to the next level. This phenomenon was first discovered in 1839 by a German scientist named Heinrich Wilhelm Dove, although the uses and benefits of Dove’s discovery remained unappreciated until the 1970s. Binaural beat technology allows the listener to achieve a specific, desired state of mind and a desired mental or physiological effect. ![]() A binaural beat is a pulsing sound perceived in the mind when each ear hears a separate tone of two slightly differing frequencies.
