摘要 特征阻抗和传播常数是表征声学材料基本性质的重要参数。利用B&K4206阻抗管测量系统,采用双空腔方法,对常见的海绵类吸声材料进行了上述参数测量,并基于测量数据建立了相应的幂函数模型,模型预测数据和测量结果吻合良好,为此类吸声材料基本声学参数的研究提供了一种方法。 Acoustical materials can be characterized by characteristic impedance and propagation constant. Measurements of above two parameters of usual sponge materials are implemented by using B&K 4206 impedance tube. Based on the measuring results, the power function models of above two parameters are also established that show a good agreement with the measuring results, which also provides a new method for the study of these materials.
