本文回顾了声波在海洋沉积物中传播的一般理论的结构，重点是从文献中的数据中确定有意义的参数。它示出的声学特性是循环应变振幅和静态应力水平的非线性函数，因此，只有有限的可用数据是有用的声学传播的研究。文中给出了一个基于该理论的地声模拟实例，并用该模型对现场实测的斯通利波速度进行了评价。
The structure of a general theory for acoustic wave propagation in ocean sediments is reviewed with emphasis on the determination of meaningful parameters from data in the literature. It is shown that acoustic properties are nonlinear functions of cyclic strain amplitude and static stress level so that only a limited amount of the available data is useful for studies of acoustic propagation. An example of geoacoustic modeling is presented based on the theory and some new data for Stoneley wave velocities measured in situ are evaluated with the aid of the model.
