Binaural beats are an auditory illusion where two oscillators, slightly detuned from each other, are played simultaneously with one perceived by each ear. The human brain mixes the audio from each ear, and the listener perceives a "beating" effect that isn't actually there. This is a well-studied phenomenon that has gained the interest of audiologists and neurologists, but it's most famous for being picked up by the alternative medicine community as a way to get high.
Stress affects your whole body, so find a pick-me-up for each of your senses. Turning on a favorite tune uses your sense of hearing for a science-backed burst of good feeling, and using aromatherapy uses your sense of smell to relax you. “Oils like lavender and lemon reduce stress,” Dr. Serani says. “Also, don’t forget that your sense of smell is the most nostalgic of all your senses,” so if you have a scent that reminds you of comfort, keep it on hand to sniff when you’re freaking out. Your sense of touch can be employed by stroking a “talisman”—a favorite or sentimental item—or even an “intention stick,” which you can hold like a wand to feel more in control. Chew gum to use your sense of taste to curb stress (scientists think it’s the lasting flavor, not just the act of chewing itself, that makes gum such a great stress reliever). Besides using your mind’s eye to visualize a happy place, you can use your sense of sight to look at calming images—cat videos on the Internet have actually been scientifically proven to lower stress.
Thanks Lorita. There hasn’t been any isochronic tones research that I’m aware of, for anti-aging, fat loss or attracting people, or any significant anecdotal feedback. You could combine positive affirmations or hypnosis scripts with isochronic tones to try and change habits and that could help with fat loss or build confidence to attract people. But it would be the affirmations and hypnosis doing most of the work, the isochronic tones would just be used to help relax the listener and put them in a more suggestible state. I don’t believe isochronic tones can affect those things, without being used in combination with some kind of vocal mental programming.
Making time for connecting with the people around you, spending time outside and doing things you love with family, friends and your spouse are all stress relievers that are good for your health in many ways. Social connection is tied to longevity, since it helps people feel like they’re a part of something larger than themselves and helps give them perspective. Being outdoors has some similar effects, reminding people that they’re one piece of a much larger universe, lifting their moods and making it easier to get good sleep. (12)
Your brainwave activity during sleep is largely distinct from your brain activity when you’re awake. (REM sleep is one exception to this—during REM, your brain is active in ways very much like when you’re awake.) During non-REM sleep, the slower, lower frequency theta and delta waves dominate, compared to the alpha and beta waves that are prominent when you’re alert and active.
Maybe a favorite popular song, a certain piece of Classical music, a raucous dance beat, the pulse of Reggae, Indian, or African drums, or the chanting of Gregorian or Tibetan monks, but you probably know how the sound of music, drumming, or chanting is capable of transporting you into an altered and joyous state of mind and uplifting your spirits.
, that is, the average of the two frequencies. It can be noted that every second burst in the modulation pattern is inverted. Each peak is replaced by a trough and vice versa. However, because the human ear is not sensitive to the phase of a sound, only its amplitude or intensity, only the magnitude of the envelope is heard. Therefore, subjectively, the frequency of the envelope seems to have twice the frequency of the modulating cosine, which means the audible beat frequency is:
It's a scenario played out every evening all over the country: Come home from work and start venting to your spouse or roommate about your day. Instead of creating a negative atmosphere the minute you walk in the door, try starting off the evening with your family or friends by exchanging good news. Something good every day, you just need to recognize it.
That all said, we are all different and have our own different limits. So I generally advise that you just be aware of how you are feeling, and if you feel like you are getting a bit fatigued from it, it’s probably time to stop or at least take a break. When listening over long extended periods, I recommend that you keep yourself well-hydrated. Your brain needs a good supply of water to function well, especially if you are studying hard and increasing your brainwave electrical activity.
Synchronized brain waves have long been associated with meditative and hypnogogic states, and audio with embedded binaural beats has the ability to induce and improve such states of consciousness. The reason for this is physiological. Each ear is "hardwired" (so to speak) to both hemispheres of the brain (Rosenzweig, 1961). Each hemisphere has its own olivary nucleus (sound-processing center) which receives signals from each ear. In keeping with this physiological structure, when a binaural beat is perceived there are actually two standing waves of equal amplitude and frequency present, one in each hemisphere. So, there are two separate standing waves entraining portions of each hemisphere to the same frequency. The binaural beats appear to contribute to the hemispheric synchronization evidenced in meditative and hypnogogic states of consciousness. Brain function is also enhanced through the increase of cross-collosal communication between the left and right hemispheres of the brain.
In one study, researchers had a group of participants relax alone in a quiet, low-light environment following an exercise session. They split the group in two — one spent 20 minutes listening to theta-frequency binaural beats while the other listened to a carrier tone and monitored their parasympathetic (rest and relaxation) and sympathetic (fight or flight) nervous system activity. Researchers found the group that listened to binaural beats experienced an increase in parasympathetic activity and a decrease in sympathetic activity, along with higher rates of self-reported relaxation.
Point #3 can easily be the case if you are still subscribing to the false idea that just listening to an entrainment track is meditation all by itself. Some unscrupulous marketing copy of various entrainment products uses phrases such as; “Our meditation CD meditates you…” which is of course, complete nonsense. I was asked recently to review one marketing ad which claimed, “With our meditation CDs you don’t need to know how to meditate…” This is worse than nonsense, it’s hogwash. That’s like saying, “If you use our wonderful plates and silverware you don’t even need to know how to cook.” If you believe that you’re unlikely to get many takers on your dinner invitations.
Changes in neural oscillations, demonstrable through electroencephalogram (EEG) measurements, are precipitated by listening to music, which can modulate autonomic arousal ergotropically and trophotropically, increasing and decreasing arousal respectively. Musical auditory stimulation has also been demonstrated to improve immune function, facilitate relaxation, improve mood, and contribute to the alleviation of stress. These findings have contributed to the development of neurologic music therapy, which uses music and song as an active and receptive intervention, to contribute to the treatment and management of disorders characterized by impairment to parts of the brain and central nervous system, including stroke, traumatic brain injury, Parkinson's disease, Huntington's disease, cerebral palsy, Alzheimer's disease, and autism.
