Paper on in situ acoustic characterization of a perforated panel on a cavity
One of the key challenges in room acoustics is accurately characterizing materials in situ—especially when traditional lab measurements aren’t feasible. This is particularly true for systems with perforated facings, which are commonly used but difficult to analyze outside controlled environments. Our latest research tackles this issue. We present a novel method for in situ characterization of rigidly-backed porous materials behind rigid perforated…
