What are Binaural Beats? A binaural beat is an auditory illusion perceived when two different pure-tone sine waves, both with frequencies lower than 1500 Hz, with less than a 40 Hz difference between them, are presented to a listener dichotically, that is one through each ear. For example, if a 530 Hz pure tone is presented to a subject’s right ear, while a 520 Hz pure tone is presented to the subject’s left ear, the listener will perceive the auditory illusion of a third tone, in addition to the two pure-tones presented to each ear. The third sound is called a binaural beat, and in this example would have a perceived pitch correlating to a frequency of 10 Hz, that being the difference between the 530 Hz and 520 Hz pure tones presented to each ear.
I find the sensation to be quite pleasant. Some consider it to be a way to increase mental energy. In my experience this was the case, it should be stated that any music I listen to that has a positive vibe and no words tends to increase my productivity, but I did feel a lift of my mood by listening to some of these tracks below.
Perhaps it’s a placebo effect – but enjoyable nonetheless.
