Sound insulation issues
This paper gives an overview of three topics related to sound insulation in buildings. The first project included laboratory and field measurements of sound insulation against aircraft noise. As well as various technical papers, the project produced software to help in the design of adequate sound insulation. In a second project, re-analysis of survey results allowed the development of a ration...
متن کاملPredicting the Sound Insulation of Walls
Between 1990 and 1998, the author published five conference papers which described the gradual development of a simple theoretical model for predicting the sound insulation of building partitions. The first aim was to extend Sharp’s model for cavity walls to cavities without sound absorption. The second aim was to remove the reported over prediction of Sharp’s model for cavity walls. The third ...
متن کاملSound insulation in multi-story timber buildings
During on an extensive investigation of a multi-story timber building with light-frame construction, several stages of the building process and their impact on sound transmission were observed. The sound insulation properties of the building components were measured before and while the buildings were occupied. Furthermore, interviews with the occupants were conducted. This procedure made it po...
متن کاملIs it necessary to measure impact sound insulation from 20 Hz in lightweight multi-storey buildings?
It has previously been notified that residents living in lightweight multi-storey family houses do not experience the impact sound insulation to be as good as in an equivalent concrete building despite the same single number rating, L’n,w+CI,50-2500. From a comprehensive national research program in Sweden, it was recently indicated that the lowest frequencies, 20-50 Hz, are crucial when it com...
متن کاملInvestigation of Acoustic Properties of Polymer Nanocomposites regarding Combined Sound Absorption and Insulation Characteristics
Introduction: Nowadays multiple techniques have been developed to noise control. One the most important way is the control based on sound absorption and insulation. The purpose of current study was to improve the acoustic properties of soft polyurethane foam regarding combined sound absorption and insulation characteristics. Materials and Methods: Polyacrylonitrile and polyvinylidine fluoride ...
