Padmanabhan and his colleagues investigated the influence of Binaural Beats on the feelings of anxiety experienced before an upcoming operation. This can be explained by the loss of control, the unfamiliar environment, along with the perceived risk of the procedure. The prospect of surgery often leaves patients feeling anxious.
The study found that stimulation with Binaural Beats, regardless of frequency, positively affected divergent thinking. Participants were given the task of finding a word that can be linked to the three others, such as combining“super” with ’market’, ‘star’ and ‘hero’. The second part of the task involved the study of convergent thinking. participants were asked to list as many uses of a specific household item as possible in a given period of time. In one part of the experiment, the researchers looked at divergent thinking, so tasks were set to test this, e.g. At the beginning of the experiment, the participants were stimulated with one of the three sound sources, and then, while the audio signal was on, they were given various tasks that required creative thinking. The order of the three experiments varied from participant to participant. In the study, 24 subjects performed 3 experiments per day: In the first, they were stimulated with a Binaural Beat using an Alpha frequency of 10 Hz, in the second with a Binaural Beat using a Gamma frequency of 40 Hz and in the third with a non-binaural, constant tone of 340Hz as a control situation. The results showed a significantly positive effect as for those exposed twice a day to 15 minutes of 5Hz Binaural Beats.Īt Leiden University in the Netherlands, an experiment explored the connection between Binaural Beats and creativity.
As part of the experiment, twenty subjects were asked to remember incoherent words and then recite them back from memory.ĭuring the study, which was conducted over a 15-day period, they heard various acoustic signals: Binaural Beats of 5Hz and 13Hz and white noise, respectively. Ortis investigated the effect of Binaural Beats on memory performance. creativity, memory, and physical aspects, such as pain.Ī study by Prof. There are a number of studies that have investigated the effect of Binaural Beats on the human body – both on cognitive processes, e.g. These can be detected and visualized on an electroencephalogram (EEG).
The effects on the brain, or “Brainwave entrainment” can be measured when a large number of neurons in the brain, send small electro-chemical signals to each other. Binaural beats are always lower than 1000 hertz (Hz) as it is at these frequencies that the brain detects the binaural beat.įor example, if the left ear registers a tone at 440 Hz and the right at 430 Hz (preferably with headphones) the binaural beat that is heard by the brain is the difference between the two frequencies - 10 Hz.Ī number of studies have proven that listening to Binaural Beats can influence brainwaves and that the brain will synchronize to the frequency given by the Binaural Beats, which is why they’re used in the Receptive Sound Therapy in SonicTonic. So the binaural auditory beat that a person hears is the difference in frequency between the left and the right ear. One of the ingredients used in SonicTonic is Binaural Beats, but what are these and how do they work?īinaural beats are sounds that are heard in the left and right ear as two slightly different frequency tones, yet perceived as one.
