Predicting trends in the sound transmission loss performance of steel-framed wall partitions using yield strength

Abstract

Mechanical properties of beams and panels are commonly used for calculating structural loads and deformation under stress and strain. Stress and strain analysis for steel beams may result in the determination of yield strength, a commonly reported steel framing property in the steel industry. This characteristic of steel framing is rarely, however, linked to trends in sound transmission loss (STL). This paper provides an analytical basis for linking the yield strength of steel framing to the STL of vertical double-leaf partitions with a focus on acoustic impedance of the beam. Experimental data are shown that validates this analytical basis. These results may be used as evidence for including the reporting of the yield strength in standardized test reports.
