Explaining binaural beats
- Binaural beats is a perceptual illusion that happens when two slightly different frequencies (notes) are played into each ear separately, usually using headphones.
- The resonance between the two frequencies is interpreted as a third sound - or binaural beat - and is heard as a frequency between the two played frequencies.
- The claim is that this third frequency prompts brain cells to begin firing at the same frequency, which purportedly is similar to the frequency of brain waves that occur during deep sleep at our most relaxed states.
