Audio Visual Entrainment – Light, Sound, and Brain 

Audio-Visual Entrainment (AVE) is a technique that utilizes pulses of light and sound at specific frequencies to gently and safely guide the brain into various brain wave patterns. By manipulating your brain wave frequencies, you have the ability to boost your mood, improve sleep patterns, sharpen your mind and increase your level of relaxation, all with the simple push of a button.

~ David Siever

Why Consider AVE? Historical Perspective

Since the concept of photic driving was discovered by Adrian & Matthews in 1943, several thousand studies have been published on the topic of AVE. In the 1950s, there was a growing interest in the subjective effects of AVE. W. Gray Walters exposed several thousand subjects to photic stimulation at various frequencies and recorded their subjective experiences.

On another front, was Dr. William Kroger. Kroger was a physician with the US military and Kroger noticed that battleships and bomber planes were being driven into enemy territory because the radar operators were being entrained into a trance state from the old-fashioned “blip” style radars. This spurned Kroger to team up with Sidney Schneider of the Schneider Instrument Company where they developed the first commercial photic stimulator in 1955, which they used primarily for hypnotic induction and pain reduction during gastrointestinal surgery and dental work. 

How It Works

Audio Visual Entrainment is capable of producing situationally appropriate brain wave frequencies through the process of entrainment, the tendency of physiological processes to mirror environmental stimuli. AVE also increases cerebral blood flow (blood flow in the brain) and increases the metabolization of glucose in the brain for improved functioning of the neurons. The combined outcome of these processes is improved mental performance. AVE is an effective, inexpensive alternative therapy for many disorders such as anxiety, Attention Deficit Disorder (ADD), Seasonal Affective Disorder (SAD), PTSD, Fibromyalgia and chronic pain. AVE devices are also used successfully to boost physical performance for athletes, academic performance for students and cognitive performance for seniors.


An important objective of entrainment is to produce a dissociative state, which is a meditation-like state of deep relaxation. It is the brain/body rehabilitative benefits produced by this deep trance-like state that makes AVE so useful for so many conditions. The dissociative state can be first observed by noticing deep and diaphragmatic breathing. Hands and feet become warmer as arteries dilate. Skin color will become pinker as blood flow increases throughout the face and body. Blood flow will increase in the brain as well. The person will experience feelings of profound relaxation and contentment as beneficial neurotransmitters are released into the brain. When in this deep state, the brain/body’s regenerative repair chemicals (parasympathetic hormones) and stabilizing neurotransmitters such as serotonin, endorphins and dopamine are released, which restore good brain function.

063 George Lindenfeld, Ph.D. is a pioneer in the field of healing trauma. Dr. Lindenfeld has been practicing for 45 years, his work including specializing in the treatment of traumatic life experiences including PTSD. He has been Executive Director of two Mental Health Centers, a university faculty member, and is a published expert brain, PTSD, and emotional trauma. Currently, he is researching and utilizing technology with a potentially far-reaching impact on the healing of trauma and other neuroinflammatory conditions. His first book (PTSD Symptoms Reversed Permanently) was written for the consumer (Combat Veteran) and significant others. His second book informs those healers who remain stuck in 18th-century theories while neuroscience is offering breakthrough information regarding the inner working of the brain. Dr. Lindenfeld continues the theme started here in this CBJ Episode – on tools for direct brain applications with surprisingly fast results.

    I got some of the best sleep of my life when I was doing this in therapy. It really does do something even if I’m not sure what that something is.

      Yes, Justin, that is the point: we’re learning about so many somethings, and appreciate your feedback!
