Sound Insulation of Open Screens: Measurement by Impulse Response Analysis
In a companion paper. Impulse Response Analysis methods were developed as a practical method of measuring the sound insulation of panels, both as partitions and as solid screens and a method for comparing the results with the standard method of measurement for transmission loss, ISO 140, was demonstrated. In this paper studies are presented on the application of the method to more complex open forms of screen. A prediction model has been used for the simpler form of screen, which shows good agreement with measurements. For the more complicated screens, which provide greater sound insulation, the results are compared with standard ISO 140 measurements.
