声学理论的一个创新r —— 振动吸声理论评述

摘要

Rayleigh's porous sound absorption theory which have been put forward one hundred years ago is not well justified by experimental results. For this reason, xin-an zhang establish a new sound absorption model.Our further works prove that zhang's theory is consistent with test results.%一百多年前英国物理学家瑞利(Rayleigh)提出的多孔材料吸声理论与实验结果吻合程度不高.为此,张新安提出一种全新的吸声理论.该文通过实测结果与理论结果的对比,进一步证实了该吸声理论的正确性.
