Machines called electroencephalograms (EEG) can measure the oscillations of brainwave patterns using a unit of frequency known as a hertz (Hz). The human brain generates electrical activity in the form of brainwaves 24 hours a day. The science of brainwave entrainment suggests that the human brain can be synchronized to the vibration of external sensory stimuli, such as sound, to reach a certain desired state, which may promote relaxation, improve sleep, reduce anxiety, and enhance creativity, among other benefits. He says he “tucks” the beats inside his music by rendering them so subtle they’re almost imperceptible, yet the brain still hears-and responds to-them nonetheless. When you listen to Hidary’s music, you will barely detect a binaural beat. “I can predict with precision exactly the way the brain will hear it.” “As incredible as the brain is, it is also incredibly predictable,” Hidary says. ![]() He’s built a library of hundreds of them, and is conscious of how each one will be perceived. This frequency, which is too low for humans to naturally detect, can help you feel calm and relaxed.Īccording to Hidary, there are technically an infinite number of possibilities for binaural beats, since there are an infinite number of frequencies. Here’s an example of how it works: If a 200 Hz tone is sent to your right ear and a 220 Hz tone to your left ear, your brain would perceive a pulsing or beating frequency of 20 Hz (20 beats per second). To listen to binaural beats correctly, you need to wear headphones. The pulsing rhythms of binaural beats reportedly provide a host of benefits, such as reduced stress, improved sleep, and enhanced creativity, but the research is often mixed. When arranged with a slow melody and harmonic movement, the result is a soothing atmospheric soundscape that is distinctly meditative and restorative. On their own, they sound like an oscillating drone. This frequency is perceived as a steady beating or pulsing pattern that influences or “entrains” the brain, and induces alpha, theta, and delta waves to achieve a state of relaxation.īinaural beats are reminiscent of other genres of ambient music, but are often more stripped down. When two (or more) steady tones attuned to different frequencies are sent to each ear, the brain perceives them as a third frequency that doesn’t actually exist.

Hidary’s catalog of binaural beats on the Insight Timer app are tailored for deep relaxation and sleep. His intention is to transport listeners to a higher state of awareness to promote relaxation and healing, similar to meditation. Hidary, who is also a yogi, has been acoustically engineering binaural beats-a technique that combines two different tones to create the perception of a single one-in his music for the past five years. That doesn’t mean that your yoga class has to be totally silent, though. “You’re trying to achieve a state of consciousness through movement by connecting mind and body you’re trying to be in that state or trance.” “If the music is too melodic or too music-y, you are hearing the music more than you are zoning into your practice,” says Murray Hidary, the Los Angeles-based composer and improvisational pianist known as Mind Travel. ![]() But teachers who do choose to use music should take special care when putting together their playlist, as some selections can be distracting. ![]() Yoga teachers are divided on whether music should be used to enhance the asana experience for their students. ![]() Heading out the door?
