Safe and Sound Protocol

The original SSP used five one-hour listening sessions to exercise regulation of middle ear muscles and related systems. The Safe and Sound Protocol is a music-based intervention developed by Stephen Porges. SSP works by shaping acoustic information that the nervous system interprets as cues of safety and trust. People with severe trauma histories require careful support when using SSP. Cues of safety can become triggers for traumatized people using SSP. SSP aims to improve social engagement, hearing sensitivity, language processing, and state regulation.
