Gamma pattern: This frequency pattern accounts for a range of 30–50 Hz.However, it can also increase anxiety at the higher end of the range. This frequency range may help promote concentration and alertness. Beta pattern: Binaural beats in the beta pattern are at a frequency of 13–30 Hz.Alpha pattern: Binaural beats in the alpha pattern are at a frequency of 7–13 Hz and may encourage relaxation.Theta patterns contribute to improved meditation, creativity, and sleep in the rapid eye movement ( REM) phase. Theta pattern: Practitioners set binaural beats in the theta pattern to a frequency of 4–7 Hz.In the study, people who received a delta pattern frequency during sleep entered a deeper stage of sleep, according to electroencephalogram (EEG) brain scan results. Delta pattern: Binaural beats in the delta pattern operate at a frequency of 0.5–4 Hz with links to a dreamless sleep.The study authors explain that there are five different categories of frequency pattern: The findings of a 2018 study suggest that listening to binaural beats for a recommended period can affect a person’s subsequent behavior and sleep cycles. The binaural beat that a person perceives is the frequency difference between the waves entering the left and right ear.įor example, if the left ear registers a tone at 200 Hz and the right ear registers one at 210 Hz, the binaural beat is 10 Hz - the difference between the two frequencies.
