I used a PANAS survey to measure student's perception of positive and negative effects of binaural beats on their performance on a timed writing assignment. I hypothesize that exposure to music containing beta frequency binaural beats (14-30 hertz) in a classroom setting will lead to a heightened individual perception of focus and other positive effects due to a process called brainwave entrainment, in which one's brain waves gradually synchronize to an external pulse (such as binaural beats) over time, possibly influencing state of mind. Much research has been done regarding the validity of these claims, but very little pertains to the potential application of binaural beats in a classroom setting where they could be used as a tool to promote a heightened sense of awareness. Binaural beats are auditory brainstem responses which originate in the superior olivary nucleus of each hemisphere. While binaural beats can be unnerving and even headache-inducing on their own, many companies market music containing binaural beats, claiming it has a myriad of therapeutic properties. For example, if a person wearing headphones were to play a 440 hertz frequency and 448 hertz frequency at the same time they would hear an 8 hertz pulsing sound as a result of the clashing frequencies.
Binaural beats are an auditory illusion perceived when two pure tone sine-waves of nearly identical frequency are presented to a listener dichotically (meaning one frequency in each ear) using some kind of stereo speaker or headphones.
