Absorption coefficients-part 1: is square area enough?

摘要

Attempting to correlate the measurements of “Absorption Coefficients' in ASTM-C4231,ISO-3542 and ISO-17497-13 it was observed that the results were varying to a large degree.An experiment was set up with 1 inch (2.54cm), 6 lb (2.72kg) density fiberglass panels havingdifferent shapes, sizes and parameters. The shapes, sizes and parameters of the panels aredescribed in this paper. The types of experiments also are described along with the process thatwas used based on input from many of the members of the industry. The end results andconclusions are described in a paper titled” Absorption Coefficients Part 2: Is “EdgeEffect” More Important Than Expected?”
