Brain Entrainment: Hemi-Sync – Binaural Beats Sound Patterns

After reading all the positive benefits of meditation, I started looking to music for meditation and came across this…

Binaural Beats

Binaural beats are auditory processing artifacts, or apparent sounds, caused by specific physical stimuli. This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz. – Wikipedia

Binaural beats appears to be growing in popularity as a form of “brain entrainment” which have been linked to the following benefits:

Does it work?

The research on this subject is a little weak at the moment, but given the powerful effect of music on the brain, I’d like to stick around and see what else comes out of this. In the meantime, you can check these out…

Research from the Monroe Institute

  • Children with ADD who listened to special binaural beat patterns in combination with amino acid supplementation improved much faster than those who used amino acid supplementation alone (Van Der Schaar, 2009).
  • Adults listening to simple binaural auditory beat stimuli during a 30-minute vigilance task improved performance and reported positive changes in mood associated with the task (Lane, Kasian, Owens, & Marsh, 1998).
  • Bariatric patients undergoing general anesthesia who were exposed to specific binaural beat combinations during surgery required significantly (1/3) less analgesia than those who listened to a blank tape (Lewis, Osborn, & Roth, 2004).

About Monroe Products

Monroe Product’s binaural beat CDs can help you experience enhanced mental, physical, and emotional states.

Robert Monroe’s work inspired an entire industry of mind/brain products. After 50 years of research, and thousands of lab sessions, the internationally acclaimed patented Hemi-Sync® process remains unparalleled in its ability to assist us in harnessing our human potential.

Thanks to the cooperation of notable medical institutions and universities, the scientifically and clinically proven Hemi-Sync® technology continues to be the focus of a variety of specialized research projects. In addition, many therapists, physicians, educators, and other professionals use Hemi-Sync® extensively.

Such research is indispensable in revealing the influence of specific Hemi-Sync® sound patterns on consciousness. Over the years, these efforts have resulted in the development of scores of individual products for specific applications such as focused attention, stress management, meditation, sleep enhancement, and pain management, to name a few.

Refined with over 50 years of research and development, and supported by numerous independent studies, reports, and articles, the patented Hemi-Sync® technology has been scientifically and clinically proven to be effective.

This unique audio-guidance process works through the generation of complex, multi-layered audio signals, which act together to create a resonance that is reflected in unique brainwave forms characteristic of specific states of consciousness.

When you hear these through stereo headphones or speakers, your brain responds by producing a third sound (called a binaural beat) that encourages the desired brainwave activity.
The result is a focused, whole-brain state known as hemispheric synchronization, or Hemi-Sync®, where the left and right hemispheres are working together in a state of coherence.

Bilingualism Resists Distraction in a World of Distractions

We live in a world of distractions. Everyday in every way, something clamours for our attention. It’s no wonder we lose track of our thoughts and the things we are doing. So how can we train ourselves to better resist these distractions and stay on task?

According to the neuroscientists, bilingualism may be the answer

Brain researchers who study bilingualism believe that the act of juggling two languages strengthens the brain system that helps people pay attention. That strong capacity to focus might be what leads to better academic performance in some children who grow up bilingual or attend language immersion programs.

In an Eriksen flanker task – which measures a person’s attention and ability to screen out unwanted stimuli – they found that Bilingual people generally perform better than monolinguals. This is because bilinguals are better at tuning out the noise. The theory is that bilingual brains may have a stronger “executive control” system because of the constant need to switch between languages. This has been likened to frequent and regular brain exercise because we are constantly using language to speak, to read and to think. So even though other cognitive activities, like practicing music and performing mathematical calculations may be just as effective, they lose out in terms of the amount of time we spend practicing those activities.

“Everything that we do that requires focused, selective attention — ignoring salient distractors that are trying to compete for attention, shifting between two things that we are trying to do at the same time, manipulating information — that is all frontal lobe, executive function stuff.” – Ellen Bialystok, Canadian psychologist at York University in Toronto.

This strong executive control system may give bilingual individuals an edge in today’s world of distractions. Bilingualism may also provide some protection for the brains of aging people as studies have shown that the onset of dementia in bilingual people occur later. The executive control system (higher brain function) is the last system in the brain to be fully developed and the first one to decline. Strengthening it with the cognitive practice of speaking multiple languages may help to slow that decline.

Bilingualism has been associated with improved metalinguistic awareness (the ability to recognize language as a system that can be manipulated and explored), as well as with better memory, visual-spatial skills, and even creativity. – The Cognitive Benefits of Being Bilingual

It should also be noted that the attention and aging benefits discussed above aren’t exclusive to people who were raised bilingual; they are also seen in people who learn a second language later in life. Looks like there is still hope for us aged monolinguals after all…

Revisiting the Mozart Effect and Other Music Benefits

music-in-action-1439016-mNew studies breathe new life into the Mozart Effect…

The ‘Mozart Effect’ was a phenomenon first suggested by a scientific study published in the journal Science in 1993. The study, involving 36 students, demonstrated that teenagers who listened to Mozart’s 1781 Sonata for Two Pianos in D major performed better in reasoning tests than adolescents who listened to something else or who had been in a silent room. Although the Mozart Effect has been largely debunked as a myth since the publication of that study, newer research continue to demonstrate the undeniable effect that music has on the brain…

‘Mozart effect': can classical music really make your baby smarter?

  • Music seems to prime our brains for certain kinds of thinking, like spatial tasks because it turns on those pathways in the brain.
  • Listening to music has a temporary effect, while learning to play an instrument creates longer-lasting effects because it creates new pathways in the brain.
  • Why Classical music? Because it has a more complex musical structure

Classical Music affects Genes Vital to Memory and Learning

In a study by Kanduri et al., 2015, 20 minutes of Mozart:

  • enhances the activity of genes involved in synaptic neurotransmission and dopamine secretion, both of which are important to memory and learning.
  • reduces the activity of genes involved in neurodegeneration

Music has the ability to enhance memory, cognitive performance and development, and emotions. The downside is that these effects were only seen in musically experienced people – another reason to learn a musical instrument…

Music’s Amazing Effect on Long-Term Memory and Mental Abilities In General

  • Professional musicians have superior long-term memory and are capable of much faster neural responses in key areas of the brain related to decision-making, memory and attention.

Bottom line:

  • Listen to music! Classical music is best.
  • If you want to train your brain, learn a musical instrument.
