Good Acoustics with Canopies - How to install them in the most effective way

Concepts for architectural acoustics consider more and more on modular sound absorbing elements like canopy islands. But without the knowledge about their operating principles it is a challenge to estimate the correct effect on the reverberation time. The aim of the research according to ISO 354 was to analyse the influence on the total absorption if we variegate different parameters like canopy dimensions, suspension height, distance between the elements and mounting angles. Beside also the contributions of the different canopy surfaces (front face, rear side and edge effects) are measured. A comprehensive understanding for these modular acoustic units will help to use them in the right way.
