Safe and Sound Protocol

What is the Safe and Sound Protocol?

Developed by Dr. Stephen Porges, founder of the Polyvagal Theory, the Safe and Sound Protocol is a non-invasive acoustic vagus nerve stimulator that helps your clients connect with themselves, others, and the world from a foundation

How Does It Work?

The Safe & Sound Protocol (SSP) is the only practical application of Polyvagal Theory, and is designed to improve sound sensitivities and auditory processing, behavioral state regulation, and social engagement behaviors through specially-filtered music.

The SSP allows for the repatterning of neural networks and improved regulation of the autonomic nervous system (ANS) for lasting change.

Based on hierarchical recruitment of the ANS, the SSP trains the middle ear muscles to tune-in to cues of safety signaled by the frequencies of human voice, which stimulates the social engagement system through the neural network associated with listening.


SSP is a music-based intervention that can address dysregulation caused by Sensory Processing Disorders, anxiety disorders, post-traumatic stress disorders, sleep disorders, Autism Spectrum Disorders, misophonia, and other factors that cause an overactive or underactive emotional state. By reducing auditory sensitivities and improving the ability to process human speech, the goal of SSP is to calm the autonomic nervous system so that the child or adult can become more social, engaged, and responsive to their own emotional needs. Other benefits may include improved digestion, improved sleep, and improved vocal tone.
