“Respondents most commonly used binaural beats ‘to relax or fall asleep’ (72.2 percent) and ‘to change my mood’ (34.7 percent), while 11.7 percent reported trying ‘to get a similar effect to that of other drugs,’” the researchers report. The survey found that 5.3 percent of respondents-over 1,600 people who completed the survey-reported using binaural beats either alone or in combination with other drugs or treatments. From there, it can be studied further and in association with other treatments or drugs.Īs part of the study, the Global Drug Survey, and independent research company based in London, reached out to people in 22 different countries (in 11 languages), and a total of nearly 31,000 responded. “This paper establishes the existence of the phenomenon of listening to binaural beats to elicit changes in embodied and psychological states,” they write. In the new research, published in the journal Drug and Alcohol Review in March, scientists set out to perform what they call the first formal study of its kind to specifically ask about binaural beats in order to establish a baseline of use around the world. Delta binaural beats may help people sleep more deeply, for example, while beta beats may help people stay more alert. Finally, gamma includes sounds from 30 to 50 Hertz apart. Alpha beats range from 7 to 13 Hertz, and beta is from 13 to 30 Hertz. Delta is the lowest frequency difference, just 0.5 to 4 Hertz. In a July 2005 paper published in the journal Anaesthesia, researchers broke down five categories of binaural beats patterns. The brain then tries to make sense of this small difference by isolating a separate 40-Hertz sound, representing the difference between what the two ears are hearing. With binaural beats, these lower-frequency sounds are piped into each side of a pair of headphones with a small difference between them-perhaps 400 Hertz on one side, and 440 Hertz on the other.

With binaural beats, the listener is bathed in two sounds that are close in frequency, which means the size and repetition of the waves that make up the sound are similar. (Pearl Jam used it for some of the songs on the 2000 album Binaural.
The term “binaural” means “two sounds,” and binaural recording-without the “beats”-refers to a kind of stereo recording wherein the listener feels totally surrounded by the musicians. To understand binaural beats, we need to lay down some basics of sound. Now, a large study of regular people shows how many have been trying binaural beats as a form of therapy or even an intoxicant. Proponents say the results affect their brains in a profound way, culminating in decades of use and study. This sophisticated recording technique uses tiny differences in frequency to generate two close tones and a third, phantom tone. In the never-ending quest to either get high or feel better, people are using a sound technology, called “binaural beats,” to mellow their minds. Different types of binaural beats may have different effects.This sound technology pairs close frequency sounds to affect the brain.
