safe & sound protocol (SSP)
The Safe and Sound Protocol (SSP), developed by Stephen Porges, is a listening-based program that supports nervous system regulation and a sense of safety in connection.
Informed by Polyvagal Theory, participants listen to specially filtered music designed to emphasize frequencies associated with the human voice. The process is intended to gently support engagement and regulation, rather than override or push the nervous system.
SSP is intended to support the conditions that allow the nervous system to feel safer over time, which may make everyday experiences feel more manageable.
Some participants notice changes in areas such as:
emotional and social engagement
comfort with sound and listening
stress response and recovery
attention and participation in daily activities.
WHO IS THE SAFE AND SOUND PROTOCOL FOR?
SSP may be offered when the nervous system has learned to remain on high alert, even when circumstances appear settled or safe.
This can show up as:
feeling easily overwhelmed or on edge
difficulty settling or winding down
heightened sensitivity to sound or social environments
challenges with connection, communication, or focus
SSP may be offered to children, adolescents, or adults, depending on individual needs and circumstances.
For children, SSP is always delivered in a way that honors cues, comfort, and consent, with caregivers supported throughout the process.
For adults, SSP may be experienced as supporting greater steadiness, presence, or tolerance for stress and social interaction.

Important Information
The Safe and Sound Protocol (SSP) is delivered as part of counselling-based and art-informed therapeutic support and is not offered as a stand-alone service. SSP is delivered by a practitioner trained and authorized to provide the protocol. Delivery is individualized, provided alongside therapeutic support, and participation is voluntary. Suitability is considered on a case-by-case basis.
SSP is informed by emerging research relating to auditory processing, nervous system regulation, and social engagement. It is not a replacement for counselling, psychological care, or medical treatment.
For NDIS participants, SSP is offered only where it aligns with plan goals, funding approval, and reasonable-and-necessary criteria. Funding eligibility is determined by the NDIS or plan manager and cannot be guaranteed.
