Do binaural beats actually work?
Is there evidence that binaural beats work?
Binaural Beats were introduced to the scientific community by biophysicist Gerald Oster in the 1970s. In recent years there has been a wave of NIH sponsored research that supports the idea that binaural beats change the brain’s state.
A study from the US National Library of Medicine titled 'The impact of binaural beats on creativity' suggests “they (binaural beats) might impose some temporal structure on neural processes and thereby reduce cortical noise (Karino et al., 2006), which again may make task-specific processes that rely on neural communication and/or synchronization more reliable.”
Another study from the Journal of Neurophysiology titled 'Neuromagnetic responses to binaural beat in human cerebral cortex' demonstrates the impact of binaural beats on brainwaves, stating "The fields showed small amplitudes; however, they were strong enough to be distinguished from the noise accompanying the recordings. Spectral analyses of the magnetic fields recorded on single channels revealed that the responses evoked by binaural beats contained a specific spectral component of BB frequency, and the magnetic fields were confirmed to represent an auditory steady-state response (ASSR) to binaural beat.”
