Further, resident satisfaction is closely correlated with increased turnover and vacancy rates (refer to “Multifamily Housing Characteristics and Tenant Satisfaction” by R. ASTM defines single-number metrics for testing of airborne sound transmission class (STC) and impact isolation class (IIC).

STC is measured in a laboratory and is used as reference during design. Due to the consistent use of STC 50 for floor-ceiling assemblies in acoustic standards for healthcare, education, and office buildings, the research for this article also uses STC 50 as a goal reference criterion.

The incompatibility of the various test reports and reference standards makes it difficult to find common ground between generic and proprietary literature. Adding mass to a floor assembly improves STC ratings (and to a lesser extent, IIC ratings) and is generally an economical way to increase acoustic performance.
