| Abstract |
With the recent introduction of light gauge steel framing systems in the concrete-dominated Korean construction industry, more buildings are built with drywall mainly composed of steel studs and gypsum boards. As building projects involving steel stud walls are increasing, higher demands in performance are requested from architects and builders, especially in the field of sound performance. A series of acoustic test were performed in a nationally certified sound-testing laboratory in order to evaluate and analyze factors that influence acoustic performance of steel stud wall assemblies. This paper analyzed factors which are influencing the acoustic performance of steel stud dry walls such as the composition and structure of steel studs, thickness and size of stud, use of resilient channel, and space of screw, etc. This paper focuses on evaluating the various factors that contribute to the acoustic performance of a drywall through laboratory measurement of airborne sound insulation. |
