| 摘 要： | 通过对声波在黄土层内传播的实验研究，本文分析了黄土介质中声波传播的强烈衰耗特性，得出了声波的衰减，这可为浅层地下声探设备的研制提供依据，黄土的声学特性依赖于其结构形状等多种因素而有所不同，而我们的实验环境和所获数据有限，因而我们的研究结果只是该问题的一个特例。

| Abstract: | This paper deals with the attenuation of sound waves as they travel through the soil. Based on the experimenal data, an absorption factor is given. Using these data will Lelp to design acoustic instruments for shallow underground. The acoustic characteristics of soil are complicated, depending on a large nunder of factors, while our exprimental enviroment is confined and data are limited and therefore our results only offer a special example. |
