Test explorer

Overlay up to eight tests. Switch between the sound reduction index, the gain over any baseline test, the receiving-room T60 and the Sabine absorption; press FIT on a test to see the ISO 717-1 reference curve and the deviations that set its rating. The URL keeps your selection, so any view can be shared.
