Acoustic ratings, briefly.

IIC · Impact sound

Laboratory impact sound rating for a complete floor-ceiling assembly, including noise from footsteps and dropped objects.

STC · Airborne sound

Airborne sound rating of a complete tested assembly, including transmission of speech and other airborne noise.

AIIC / FIIC

Impact ratings measured in an actual building. Use the designation stated in the report.

ΔIIC

Impact insulation improvement relative to a reference bare concrete slab under specified test conditions.
