Scattering Uniformity Measurements and First Reflection Analysis in a Large Non-Anechoic Environment
A new campaign of experiments was run on the floor of a large room to obtain a long enough anechoic time window: this permitted to study the first reflection from the panels themselves and their diffusion uniformity. The results are discussed, comparing them with past measurements and with the ones from a simplified set-up with a smaller geometry. Some key matters to measurement are discussed, they were proposed in a recent comment letter posted to the specific AES-4id document committee on its reaffirmation. An analysis of the single reflection and reflectivity data was undertaken to investigate the behavior of a perforated panel and the measurement set-up overall potential.
