Dr. Stephen Porges, the founder of Polyvagal theory, developed the Safe and Sound Protocol (SSP) after 40 years of research on the relationship between the autonomic nervous system, auditory sensitivities and social emotional processes. SSP utilizes a music-based intervention to address dysregulation caused by Sensory Processing Disorders, anxiety disorders, post-traumatic stress disorders, sleep disorders, Autism Spectrum Disorders, misophonia, and other issues due to an overactive or underactive emotional state. The sound based intervention has been found to calm physiological and emotional states by reducing stress, and is accomplished using music of that has been filtered through a patented, evidence-based algorithm that highlights specific sound frequencies to help regulate the autonomic nervous system and stimulate the vagus nerve. Safe and Sound Protocol is not counseling/behavioral health and not a substitute for therapeutic treatment. SSP is meant to complement the work an individual is already doing (or will be doing) in therapy.
