Good acoustics with canopies - how to install them in the most effective way

摘要

Concepts for architectural acoustics consider more and more 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 analyze the influence on the total absorption if we variegate different parameters like canopy dimensions, suspension height, distance between the elements and mounting angles. Beside that also the contributions of the different canopy surfaces (front face, reverse side and edge effects) are measured. A comprehensive understanding for these modular acoustic units will help us to use them in the right way.
