Abstract

Material-selection charts, in the form of grouped scatter plots of material properties of solids, are known to be useful in structural engineering, and as a conceptual tool for teaching. In this article similar plots for the properties of liquids and gases are introduced, and their application to the teaching of acoustics is discussed. Analogous charts for musical strings are presented, highlighting the analogy between the properties of wave-bearing fluids and those of wave-bearing strings. Data from one manufacturer show consistently higher tension for bowed strings than plucked strings, with the exception of the bowed erhu and the plucked mandolin, both of which have intermediate tension. Questions that could be discussed in class or form the basis of student investigations are suggested throughout.

声学课程的散点图

材料选择图是固体材料特性的散点图，在结构工程中很有用，也是教学的概念工具。本文介绍了液体和气体性质的相似图，并讨论了它们在声学教学中的应用。给出了琴弦的类比图，突出了承波流体与承波琴弦性质的相似性。来自一家制造商的数据显示，弓弦的张力始终高于弹拨弦，但弓弦二胡和弹拨曼陀林除外，两者都有中等张力。可以在课堂上讨论或形成学生调查基础的问题贯穿始终。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
