One larger 2011 randomized and controlled trial looked at the use of binaural beats in 291 patients admitted to the emergency department at a hospital.Since the study was small, uncontrolled, and relied on patient surveys to collect data, larger studies will be needed to confirm these effects. The results of the study found that listening to binaural beats for 60 days significantly reduced anxiety and increased the overall quality of life of these participants. A 2007 uncontrolled study asked eight adults to listen to a binaural beat CD with delta (1 to 4 Hz) beat frequencies for 60 days straight.In the study, anxiety levels were cut in half for people who listened to the binaural beat audio. An older 2005 controlled study in roughly 100 people about to undergo surgery also found that binaural beats were able to significantly reduce pre-operative anxiety compared to similar audio without the binaural tones and no audio at all.While most studies on the effects of binaural beats have been small, there are several that provide evidence that this auditory illusion does indeed have health benefits, especially related to anxiety, mood, and performance. Is there any research to support the claims? You may also want to listen with your eyes closed. Remember, you must use headphones for binaural beats to work. For example, if you’re experiencing high levels of anxiety or stress, you may want to listen to the audio for a full hour or longer. You can experiment with the length of time you listen to the binaural beats to find out what works for you. Listening to the binaural beat audio for at least 30 minutes each day in your headphones ensures that the rhythm is entrained (has fallen into synchronization) throughout the brain. When listening to binaural beats, it’s best to sit in a comfortable place free of distractions.
