binaural beats frequencies and effects pdf

To use binaural beats, tune them to the frequency of a desired brainwave and listen using headphones. Also, older individuals may not respond to binaural beats as effectively as younger individuals, especially at higher frequencies. For example, individuals who experienced aphasia after a severe cerebrovascular accident (stroke) did not show any response to binaural beats. Note: Certain types of brain damage can impair an individual's ability to hear binaural beats. Gamma (32–100 Hz) – Learning, problem solving.Beta (15–20 Hz) – Focus, sustained thought, excitement.Alpha (8–13 Hz) – Moderate alertness, meditation, recall.Theta (4–8 Hz) – Sleepiness, meditation.Lower-frequency beats may make memory worse acutely, by producing neural states that are incompatible with encoding information.īecause binaural beats require a unique sound played into each ear, headphones should be used.Ī number of binaural beat generators are available, most of which offer the option to set a base frequency (often between 200 and 400 Hz) followed by a binaural frequency, the former being the average frequency between each of the tones played in each ear and the latter being the difference between the two frequencies.īinaural frequencies are often set to match certain brainwave frequencies, depending on the desired effect: Lower-frequency binaural beats in the delta, theta, and alpha ranges seem to produce relaxation and pain reduction, and higher frequency beats in the beta and gamma range may be able to improve memory. While binaural beats have been investigated for a variety of outcomes, the best evidence lies in their effects on memory, relaxation, and pain.

Developing adequate controls is difficult with a treatment like this, which is worth keeping in mind. Broadly speaking, binaural beats seem to have modest to strong effects on sleep, memory, attention, mood, and pain.Ī quick note about the studies: the “control” groups vary considerably, and include silence, white noise, music, and sham sounds. Although binaural beats have been studied in diseases such as Parkinson’s, cardiovascular disease, and tinnitus, the bulk of the research has been dedicated to improving sleep, cognitive factors, and pain.
