These otherworldly beats are popular on YouTube and promise to heal everything from sleep disorders to anxiety, while improving poor memory and anemic levels of happiness. Some people believe that as soon as binaural beats give your brain a new frequency, your brain waves feel compelled to synchronize with it, effectively putting you in a different “brain state.” Your brain goes into an “alpha state” when your focus is inward (as in meditation) and a “beta state” when your attention is focused on the world around you. Some people believe that as soon as binaural beats give your brain a new frequency, your brain waves feel compelled to synchronize with it, effectively putting you in a different “brain state.”
When Trimberger found out about binaural beats for the first time, she said she started searching and found a free recording online.
What do binaural beats do to your brain?
Binaural beats are said to trigger the same mental state as a meditation practice, but much faster. Some evidence suggests that the perceived sound can alter brain waves through a process called entrainment, in which brain waves are based on an external shock or frequency. There are studies that show that binaural beats induce delta activity in the brain and thus prolong deep sleep. When you hear a sound at a specific frequency, your brain waves synchronize with that frequency.
A binaural beat with a frequency between 4 and 7 Hz, for example, is more like theta brain waves and thus promotes sleep and relaxation.
At what frequency is the brain repaired?
Clinicians have used gamma frequency stimulation to help treat language and learning difficulties (particularly in children), depression, ADHD, Alzheimer’s disease (patients with this disease typically produce very low gamma activity), and even autism. Beta is a “fast” higher frequency bandwidth that is typically associated with external awareness, complete alertness, and rapid thought generation. Studies suggest that delta is typically underproduced in cases of chronic stress or sleep disorders (even in people who voluntarily choose to sleep deprivation), and that a lack of this frequency may play a role in Parkinson’s disease, diabetes, and schizophrenia. Many researchers regard this high-frequency brainwave as the key to cognition and the optimal functional frequency of the brain — particularly at 40 Hz.
