Sažetak
Resonator absorbers are widely used for tuning the acoustic characteristics of spaces. This thesis extends the research with a resonator prototype with adjustable acoustic characteristics (absorption and diffusion) by using two movable perforated plates with 4 sections, all containing different depths. Presented tools include a complete absorption calculation model by using impedance layers, corresponding computer simulator, and a script for calculating 2D binary diffuser layout of choice. A demonstration of validity for the model was given, by using measurements Kundt’s tube and comparing them to mathematical model.
