We observed Realtive Power (RP) increase in theta and alpha bands and decrease in beta band during delta and alpha Binraul Beats (BB) stimulations. Results suggest that the presentation of binaural auditory beats can affect psychomotor performance and mood.īut I also found this: "Tracking EEG changes in response to alpha and beta binaural beats", sayingĪnalysis of changes in broad-band and narrow-band amplitudes, and frequency showed no effect of binaural beat frequency eliciting a frequency following effect in the EEG.Īnd finally Analysis of EEG activity in response to binaural beats with different frequencies In addition, the beta-frequency beats were associated with less negative mood. Presentation of beta-frequency binaural beats yielded more correct target detections and fewer false alarms than presentation of theta/delta frequency binaural beats. However, participants were kept blind to the presence of binaural beats to control expectation effects. Participants (n = 29) performed a 30-min visual vigilance task on three different days while listening to pink noise containing simple tones or binaural beats either in the beta range (16 and 24 Hz) or the theta/delta range (1.5 and 4 Hz).
