Describes methods for determining four indices for rating the properties of partitions, including walls and floor-ceiling assemblies, used to divide spaces in domestic and commercial buildings in reducing the transmission of airborne sound; the four indices are sound transmission class, field sound transmission class, noise isolation class, and normalized noise isolation class.

This standard describes methods for the determination of the following indices for rating the properties of partitions (including walls and floor-ceiling assemblies used to divide spaces in domestic and commercial buildings) in reducing the transmission of airborne sound: (a) Sound transmission class (STC) (b) Field sound transmission class (FSTC) (c) Noise insolation class (NIC) (d) Normalized noise isolation class (NNIC).
