Simulation versus measurement of acoustical banners

Abstract

This study compares the results of measurements and simulations for variable acoustical banners in several venues. Reverse calculations of real venues reveal a wide spread of achievable absorption coefficients for banners. When modeling these spaces and materials in pre-design, it is critical to use the correct absorption coefficients for accurate results. This presentation will explore the different ways of modeling banners using classical ray tracing acoustic simulation software and offer recommendations for interpreting absorption coefficients provided by banner manufacturers.
