The Safe and Sound Protocol (SSP)
Thursday January 16, 2020

What is the Safe and Sound Protocol (SSP)?

The Safe and Sound Protocol (SSP) is a five-day intervention designed to reduce stress and auditory sensitivity while enhancing social engagement and resilience.  The intervention uses prosodic vocal music that has been filtered to train the middle ear muscles to focus in on the frequency envelope of human speech.  Once human speech is properly perceived, the portal to social engagement has been opened.  You’ll find you are (or your child is) better able to interpret not only the meaning, but also the intent in conversations.  And the sense of safety that is achieved by better understanding the fluctuations in human voice calms your (or your child’s) physiological state.  Once your system has been primed and your state is calm, further therapy is enhanced and behavioral regulation is improved.  

Who would benefit from the SSP?

  • Children and adults who have experienced traumatic events or spend much of their day in “fight or flight”
  • Auditory Hypersensitivity
  • Children and adults who struggle with self-regulation

SSP Usage and Guidelines

At Kinetic Edge Physical Therapy, the first session of the SSP is completed in office. This allows the therapist to educate the child and family on how to complete the SSP to obtain the maximum benefit. The next four sessions are to be completed at home for four consecutive days (for a total of 5 one-hour sessions). There is a one-time $50 rental fee for the SSP as it is not currently covered by insurance. Talk with your therapist if a day must be missed for some reason.

When completing the SSP it is advised to use the following guidelines:

  • Ensure the child feels safe and the environment is calm
  • Minimize any external noises, including talking
  • NO SCREENS may be used while listening
  • Complete preferred play activities that do not cause physiological arousal in the child
  • Minimize people coming in and out of treatment room, minimize extra people in the room
  • Encourage child to purposefully listen to the music but, discourage singing along/dancing
  • It is OK to eat non-crunchy foods or drink non-carbonated beverages while completing the SSP
