Summary:

Sound absorption for multiple materials was measured in a small reverberation room using different sample sizes. The largest samples were cut to progressively smaller sizes to study the effect of sample size on sound absorption. The materials tested included three different recycled fibers, two PET fibers with facers, and one open-cell foam. These materials spanned low, medium, and high sound absorption over the range of test frequencies. The results for each material and each sample size are reported and compared. Comments are provided on sample size for labs with small reverberation chambers. These results will be considered in the development of an SAE test method for sound absorption using small reverberation rooms
