Of course, this emerging field has yet to be conclusively proven one way or the other. "Most of the time when I am at work, I use a concentration-focused binaural beat that really helps me focus more than any other tool," she emails, noting that she prefers to get her beats from the app Binaural Chakra Therapy. "For example, if you listen to a 290-hertz tone in your right ear and 300-hertz in your left ear your brain will actually absorb a 10-hertz tone."Įlizabeth Davidson, of Moline, Illinois, turns to binaural beats almost every day, and is just one among legions of people who swear by their effects. When each ear is exposed to two different frequencies at the same time (one in each ear) the brain actually hears a single tone that is the difference between two separate frequencies, and your brain tunes into this new frequency," says Melissa Gentry, life coach and CEO of Healing the Love via email. "Binaural beats combine two slightly different sound frequencies to create the perception of a single frequency tone. In fact, when done right you won't hear any discernible beat at all. These aren't the sort of sounds you're likely to hear in the club, though. If you're looking to achieve total relaxation, lower your stress, manage anxiety, enjoy better quality sleep or even ramp up your focus, it might be time to drop the beat - binaural beats, that is. (D) Scalp electrodes used in the EEG recording (in green).Science is divided on whether binaural beats have any value, but many people swear by them. In red, the time windows used for the analyses of the EEG band power (EEG: above) and psychophysiological measures (electrocardiogram, ECG and skin conductance response, SCR: below). ![]() Experimental blocks consisted on 90 s of pink noise, followed by 180 s of acoustic or binaural beat at the corresponding frequency, followed in turn by 90 s of pink noise. (C) Experimental protocol and time-windows for analysis. Thus, a beat whose frequency corresponds to the frequency difference between them (34.49 Hz) is generated within the auditory pathway. One pure tone (373 Hz) is presented to one ear while another (407.49 Hz) is presented to the other ear. (B) Illustration of the binaural-beat condition with a beat frequency within the EEG gamma range. Consequently, a beat is generated whose frequency corresponds to the frequency difference between them (34.49 Hz). Two pure tones of slightly different frequencies (373 Hz and 407.49 Hz) were presented simultaneously to the two ears. (A) Illustration of the acoustic-beat condition with a beat frequency within the electroencephalographic (EEG) gamma range. Our results do not support binaural-beat stimulation as a potential tool for the enhancement of EEG oscillatory activity, nor to induce changes in emotional arousal.ĮEG bands acoustic beats binaural beats heart rate skin conductance. ![]() In the psychophysiological measures, no changes in heart rate and skin conductance were observed for any of the beat frequencies presented. Additional analysis of spectral EEG topographies yielded negative results for the effect of binaural beats in the scalp distribution of EEG spectral power. For all the beat frequencies used for stimulation, no significant changes between Baseline and Beat epochs were observed within the corresponding EEG bands, neither with binaural or with acoustic beats. In each of these epochs, we analyzed the EEG spectral power, as well as calculated the heart rate and skin conductance response (SCR). Beats of five different frequencies (4.53 Hz -theta-, 8.97 Hz -alpha-, 17.93 Hz -beta-, 34.49 Hz -gamma- or 57.3 Hz -upper-gamma) were presented binaurally and acoustically for epochs of 3 min (Beat epochs), preceded and followed by pink noise epochs of 90 s (Baseline and Post epochs, respectively). Additionally, we analyzed the effects of binaural-beat stimulation on two psychophysiological measures related to emotional arousal: heart rate and skin conductance. In the present study, we explored the potential contribution of binaural beats to the enhancement of specific electroencephalographic (EEG) bands, as previous studies suggest the potential usefulness of binaural beats as a brainwave entrainment tool. If these two tones are presented one to each ear, they still produce the sensation of the same beat, although no physical combination of the tones occurs outside the auditory system. When two pure tones of slightly different frequencies are delivered simultaneously to the two ears, is generated a beat whose frequency corresponds to the frequency difference between them. ![]()
