Įntrainment isn’t unique to binaural beats in fact, it is a common aspect of brain function. According to some researchers, b inaural beats could then enhance or suppress the different cognitive and emotional functions associated with different types of brain waves. The idea behind binaural beats is that listening to them could increase the strength of certain brain waves throughout the brain. This synchronization of neural activity across different brain areas is called “ entrainment” and is the main way that binaural beats cause changes in our brain waves. In other words, this part of the brain acts like the conductor of an orchestra, coordinating and synchronizing the activities of many neurons throughout the rest of the brain. The superior olivary complex can be ‘tricked’ into hearing a beat when it senses two close frequencies it responds by synchronizing neuronal activity in other parts of the brain. įig (a): Schematic depiction of the seeds in the auditory pathway: Primary auditory cortex (PAC) medial geniculate nucleus (MGN) inferior colliculus (IC) and superior olivary complex (SOC). This brain area allows us to identify the direction of sounds. The part of our brains that first processes sound inputs from both ears is called the superior olivary complex, which is located in the brain stem. Available studies are small and low quality.Some participants reported negative emotions (anger, confusion, anxiety).May increase creativity and cognitive flexibility.May improve focus, attention, and memory.For example, if you listened to two frequencies at 200 Hz and 210 Hz, the beat would arise at a frequency of 10 Hz (or 10 “beats” per second).īut how could this affect the brain? To answer this question, we first need to know about brain waves. The rate (frequency) of a beat is equal to the difference between the two frequencies being played. As the frequencies get closer together, we begin to hear a slow pulsing beat between the notes of the two strings. The same phenomenon arises when tuning two guitar strings. When wearing earphones that are playing slightly different notes in each ear, our brain perceives the volume to pulse (oscillate) at a fixed rate. Read on to learn more about binaural beats.īinaural beats are an auditory illusion perceived by the brain when two slightly different frequencies of sound are played into each ear ( bi – two, aural- ear). Listening to binaural beats is free, safe, and increasingly popular proponents claim it can help maintain good mental health. “Binaural beats” are a specially designed type of sound intended to boost your concentration, enhance your creativity, and improve your mood.
