Acoustic stimulation reduced PTSD symptoms in small study


Wake Forest’s Charles H. Tegeler has found that non-invasive brainwave mirroring technology significantly reduced symptoms of post-traumatic stress in soldiers.

High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM) is used as a non-invasive, closed-loop, acoustic stimulation approach. Algorithms translate brain frequencies into audible tones in real-time.

Tegeler compares this to an “acoustic mirror.” Through resonance between brain frequencies and acoustic stimulation, the brain makes self-adjustments to improve balance and reduce hyperarousal, with no conscious, cognitive activity. This supports the brain to reset stress response patterns that  caused by repetitive traumatic events.

In a small study, reductions in post-traumatic symptoms, including insomnia, depressive mood, and anxiety were observed in subjects for  six months after the HIRREM protocol.
