Vibroacoustic Therapy (VAT) & Brainwave Entrainment

Vibroacoustic Therapy (VAT) & Brainwave Entrainment

Imagine… you sit comfortably in a chair that acts like an electronic tuning fork to vibrate your whole body. The multi-layered sounds you hear and feel are designed to take your brain and central nervous system into a deeply relaxed –healing state. You’re wearing glasses that transform what you hear into mandala-like patterns of light…imagine your brain, in balanced harmony.

So much of our day is spent thinking – planning, organizing, analyzing. This is all left brain, beta, activity – in and of itself, a good thing. But, as in all things, you need balance.

To be healthy, you need balanced use of the right and left hemispheres of your brain and you need to be able to shift down into slower brain wave states.

Although several distinct brain wave pattern types have been identified, there are four patterns that we work with, specifically. In descending order of wave speed, called frequency, these patterns are known as beta, alpha, theta and delta, which is deep sleep.

As we slow our brain wave activity from beta to alpha, and then down to theta and delta, the two sides of the brain become more balanced. This is called brain synchrony. EEG studies have shown that in deep meditative states this synchrony becomes a balanced state of whole brain integration. This synchrony provides “the maximum efficiency of information transport throughout the brain – the scope of your awareness is widened a great deal, so that you’re including many more experiences at the same time.” – Lester Fehmi, Director of the Princeton Biofeedback Research Institute

What is Vibroacoustic Therapy (VAT) & Brainwave Entrainment?

VAT is the use of very low frequency transducers embedded in a chair or massage table that act like electronic tuning forks to cause deep physical relaxation. Brainwave entrainment uses specialized audio recordings with a uniquely-designed sound/light system to facilitate changes in brainwave states. These changes allow clients to reach deeper states of relaxation and awareness.

The recordings I use were developed by Dr. Jeffrey Thompson of the Center for Neuroacoustic Research. Each recording uses binaural beat technology, which introduces separate sounds into each ear, causing an interference pattern of pulses calibrated to specific brainwave speeds. These speeds or frequencies fall within the ranges commonly referred to as Beta, Alpha, Theta, and Delta. The brainwaves will follow the frequency of these pulses and brainwave entrainment will occur.

The sound heard through the headphones entrains the auditory cortex. The sound frequencies are converted into light, affecting the visual cortex through the light goggles. The low frequency sound vibrations are felt through the chair; these are processed in the brain-stem at the level of the vagus and glossopharyngeal nerves, activating the parasympathetic nervous system. With so much of the brain entrained to the same frequencies, whole brain synchrony occurs, improving information transport throughout the brain and balancing the body/mind complex.

Common names for specific brainwave states that fall within a range of frequencies:

Betaconcentration and alertness. High levels of beta can cause anxiety.

Alphadeep relaxation. Higher frequencies of alpha = relaxed/focused state.

Thetadreaming sleep, increased creativity, super-learning, integrative experiences and increased memory.

  • Behavior and belief system changes can be made more easily
  • Open receptivity to learning
  • Integrative experiences leading to feelings of psychological well-being
  • Psychologically healthier

Deltadreamless sleep. If alert, a very deep, trance-like, non-physical state. Large quantities of DHEA, the growth hormone, are released – this is natural ANTI-AGING. š The body heals and repairs itself, in this state.
