Performance enhancement study of acoustical privacy screens
AbstractBased on the modelled results and both economic and technical considerations, revised element configurations were selected which incorporated a slightly thicker fibreglass layer, in conjuction with a perforated back pan having low percentage, small diameter perforations. Modified prototype screens were tested in an ASTM accredited laboratory, and were found to exhibit NRC values on the order of +0.15 higher than the corresponding benchmark models.
