本文研究了不同等级(0.0046，00，1，3)和密度(0.0046-0.22g/cm~2)钢丝棉的声学性能。提出了一种从声波到羊毛的动量和热传递的理论。在173、480和1440赫兹频率下获得的实验证据证实了理论的预期精度。
This is a study of the acoustic properties of various grades (0000, 00, 1, and 3) and densities (0.0046–0.22 g/cm2) of steel wool. A theory that accounts for momentum and heat transfer from the acoustic wave to the wool is presented. Experimental evidence, obtained at frequencies of 173, 480, and 1440 Hz, confirms the theory to the expected accuracy.
