Sound Absorption

Sound absorption research focuses on accurately measuring and modeling how materials reduce sound energy. Current efforts concentrate on improving in-situ measurement techniques, often employing microphone arrays and advanced signal processing algorithms like the discrete complex image source method to account for complex wave reflections. These advancements are crucial for validating time-domain simulation models, which are increasingly important for predicting the acoustic behavior of absorbers in diverse applications. Ultimately, improved understanding and modeling of sound absorption will lead to more effective noise control strategies in various fields.
