Is 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 کاملSound 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 کاملLightweight Partitions Having Improved Low Frequency Sound Insulations
The sound insulations were measured of a range of single, double and triple leaf partitions. For the single leaf partitions, a staggered stud configuration was used. For the double and triple leaf partitions, the configuration of the boards was different from that in the conventional Camdens. At low frequencies, the partitions tested generally had higher sound insulations than comparable metal-...
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 کاملSound Insulation in a Hollow Pipe with Subwavelength Thickness
Suppression of the transmission of undesired sound in ducts is a fundamental issue with wide applications in a great variety of scenarios. Yet the conventional ways of duct noise control have to rely on mismatched impedance or viscous dissipation, leading the ducts to have ventilation capability weakened by inserted absorbers or a thick shell to accommodate bulky resonators. Here we present a m...
