What is the Safe and Sound Protocol (SSP)?

Whatisthessp.com is a website that explains the SSP.


Developed and patented by Dr. Stephen Porges, the SSP is a 5-hour auditory intervention based on his Polyvagal Theory. The SSP is designed to reduce stress and auditory sensitivity while enhancing social engagement and resilience. It presents music that has been acoustically modified based on a specific algorithm that triggers physiological states of safety and trust. Calming the physiological state helps to promote social engagement and self-regulation and further therapy is enhanced or even accelerated. 

Included in the program are three playlists, one geared toward adolescents and adults that contains a range of diverse popular and folk songs and one that is geared toward children, which contains a selection of Disney and other childhood favorites songs. Our most recent playlist is classical music.


Common applications for SSP include: 

  • trauma and anxiety
  • auditory hypersensitivity
  • inattention
  • behavioral dysregulation
  • difficulty with social communication
  • preparation for therapy
