Safe and Sound Protocol (SSP)

The Safe and Sound Protocol (SSP) is an evidence-based listening therapy designed to reduce sound sensitivities and improve auditory processing, behavioral state regulation, and social engagement behaviors through filtered music.

As a practical application of Polyvagal Theory, the SSP acts as a non-invasive acoustic vagal nerve stimulator, helping to retune the nervous system to better support connection, collaboration, and resilience.

The SSP involves listening to specially filtered music through headphones while remotely connected to a provider.

SSP has demonstrated benefits for individuals with trauma, anxiety, sensory processing differences, and more.

Highlights of the SSP:

A 5-hour auditory intervention developed and patented by Dr. Stephen Porges, author of the Polyvagal Theory.
Designed to reduce sound sensitivity and improve auditory processing and behavioral state regulation.
Activates the client’s social engagement system, helping to accelerate and enhance therapeutic outcomes.
Supports physiological state regulation, allowing for greater resilience

Polyvagal Theory: the Science of Feeling Safe

Developed by world-renowned researcher and Unyte’s Chief Scientific Advisor, Dr. Stephen Porges, Polyvagal Theory focuses on what is happening in the body and the nervous system and explains how our sense of safety, danger, or life threat can impact our behavior. Learn more about Polyvagal Theory.

What Happens in an SSP Session?

Each 50-minute session includes:

Listening to the filtered music at a pace tailored to your system
Somatic tracking to observe activation, settling, or shifts
Grounding and regulation tools to support your body
Integration, connecting the experience to patterns in daily life
Between-session monitoring for safety and personalized adjustments

SSP is not just music—it’s an attuned, guided nervous system process.

Is SSP Done Alone or With My Partner?

SSP is completed individually, as each nervous system responds differently and requires personalized pacing. Many couples choose for both partners to complete SSP separately for deeper relational transformation.

What Results Can I Expect?

Every nervous system is unique, but many clients experience the following:
