Improving the sound insulation of existing wooden floor constructions – experiences from a laboratory study
During the design process for housing, the sound insulation performance is determined considering material properties and flanking sounds according to international standards, guidelines and material specifications. Typically, simulation software is also included in this process. Building elements and junctions are carefully designed and analysed. While the design stage is vital, the construction process and application of acoustic details are equally important. Some unforeseen circumstances at construction stage can include changes in materials, incorrect application that causes flanking sound transmission, disruption of materials and sound leaks through unfilled mortar etc. Therefore, verification studies are necessary through acoustic measurements. Countries differ in requirements for the verification. Some countries may require measurements after construction, while others require only inspection at site, or in some cases calculation reports are sufficient. Therefore, cross studies are important to ensure that acoustic calculations will actually comply with the measurement results. The intention of the study aims to contribute to comparison of acoustic calculation results with site measurements. Six existing buildings were measured and acoustic performance was calculated using dedicated software packages. Some issues are highlighted that cause variance between the results. ; Many Danes live in older apartment buildings with wooden floor constructions with timber joists. Common for these is that the sound insulation is poor. However, these floors often have a regular design, which indicates that a good improvement strategy would work for many apartments. Moreover, the simple wooden flooring makes it possible to dissemble down to the load-bearing beams. In this paper we report experimental laboratory work investigating how to improve the sound insulation of such wooden floors by renovation. The goal is to improve the sound insulation to fulfill the Danish building regulations, considering both airborne and ...
