Predicting 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 ...

Sound Transmission through Duct Walls

Acoustic &&breakout'' and &&breakin'' through duct walls had, until the late 1970s, been a rather neglected topic of research, particularly in the "eld of heating, ventilating and air-conditioning ducts. Since then, interest has grown and many publications have appeared in which predictive methods have been reported. Research in this area, especially that which has been conducted over the past ...

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...

Transmission of Low-frequency Internal Sound through Pipe Walls

Transmission loss measurements are reported for long steel pipes of circular crosssection, with air inside and out, excited by internal sound. At low frequencies (wavelength greater than the pipe diameter), most of the radiated sound is accounted for by pipe bending waves. In order to approach the much higher transmission loss predicted for pure breathing motion of the pipe, bending waves must ...

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...
