This is a social story that assigns volume levels for different areas in schools. I can personalize the words in the story to have up to 4 different areas (one for each level) and the name of your specific student. I would need approximately 48 hours to personalize and resend.
There are voice level chart materials. I printed mine onto Astrobrights card stock and it looks great! There is a pic of how I posted the levels in my room on thumbnails.
