Binaural acoustics are created when two different and pure tones are simultaneously presented, one to each ear. For example, if 120 Hz are played in the left ear and 130 Hz are played in the right ear, the perceived frequency of the signal will be 10 Hz. Because a binaural tone often occurs at low wavelengths, it is sometimes called auditory illusion. In order for you to detect binaural acoustics, you need to wear headphones like those created by Erin Stair, MD, called Zenband. Many Zenband users report improvements in dealing with stress and anxiety, depression, sleeplessness, and inability to focus. If you are looking for a holistic, natural, effective, and noninvasive approach to your sleepless nights, binaural beats might just be for you.
Some recent research suggests that binaural stimulation calms down the autonomic nervous system, stimulates the parasympathetic nervous system (vagus nerve), and alters brain connectivity in other ways. Theoretically, the binaural acoustics will entrain an individual’s brain to an external rhythm, and the tones need to be presented in a specific sequence and at a specific frequency for best results. (Entraining is the equivalent of your brain following a rhythm like your muscles do while dancing to music.) This research is good news for anyone looking to improve their sleep, reduce stress and anxiety, improve focus, and alleviate headaches. Some doctors are even using binaural tracks to help soldiers suffering from PTSD. Source: bloomingwellness.com
