On the other hand, our measures of heart rate and skin conductance did not support the effect of binaural beats on emotional arousal. Thus, our results altogether do not support binaural beats as a potential brainwave entrainment tool, nor they suggest any beneficial effect on clinically relevant dimensions.

Anaesthesia 60, — More recently, they have been connected to potential health benefits. Binaural beats are claimed to induce the same mental state associated with a meditation practice , but much more quickly.

In effect, binaural beats are said to:. Meditation is the practice of calming the mind and tuning down the number of random thoughts that pass through it. A regular meditation practice has been shown to reduce stress and anxiety, slow down the rate of brain aging and memory loss, promote mental health, and lengthen attention span. Practicing meditation regularly can be quite difficult, so people have looked to technology for help.

Binaural beats between 1 and 30 Hz are alleged to create the same brain wave pattern that one would experience during meditation. When you listen to a sound with a certain frequency, your brain waves will synchronize with that frequency. The theory is that binaural beats can help create the frequency needed for your brain to create the same waves commonly experienced during a meditation practice.

The use of binaural beats in this way is sometimes called brain wave entrainment technology. All you need to experiment with binaural beats is a binaural beat audio and a pair of headphones or earbuds. You start to hear a third sound, a rhythmic beat that does not exist.

Try it for yourself, here. Binaural beats do induce brain wave entrainment, or brain waves synchronizing to a rhythmic sonic stimulus, but not any better than normal beats. In both types of beats — binaural and monaural beats — the team did not observe a significant effect on mood or cognition. The claims that binaural beats will help memory or attention or relaxation seem a bit fuzzy to us, based on our results.
