This award supports two related projects within the context of musical acoustics. These represent two complex problems involving energy transfer in metal structures. In the case of impacted plates, it has been shown that equations developed in the 19th century can be used to describe the steady-state motion of thin plates with some success. However, predicting the transient response of plates to an impact has proven to be a less tractable problem. The work supported here will lend insight into the physics of the struck plate, primarily by comparing experimental work to the results of computational modeling. The interaction between vibrating air and the walls that contain the air is likewise a complex problem of broad interest. Several possible explanations have been posited to account for the audible effects reported in the literature, but as of this date none have been supported by experimental data. The primary goals of this work are to understand the transient response of struck plates within the context of idiophones, and to determine how structural vibrations affect the sound of brass wind instruments. he study of musical instruments is interesting to undergraduate students, and therefore, having a research program in this area naturally attracts young minds. While the systems under study involve musical instruments, the research centers on studying basic physical phenomena which are not unique to musical acoustics. Thus, students are introduced to important scientific research through a subject they find fascinating.

该奖项支持音乐声学背景下的两个相关项目。 这代表了涉及金属结构中能量传递的两个复杂问题。在受冲击板的情况下，已经表明，世纪发展起来的方程可以用来描述薄板的稳态运动，并取得了一定的成功。然而，预测板对冲击的瞬态响应已被证明是一个不太容易处理的问题。这里支持的工作将有助于深入了解撞击板的物理特性，主要是通过将实验工作与计算建模的结果进行比较。振动的空气和包含空气的壁之间的相互作用同样是一个广泛关注的复杂问题。几种可能的解释已被假定为占在文献中报道的听觉效果，但截至目前，没有一个被实验数据支持。 这项工作的主要目标是了解内的背景下，被击中的板的瞬态响应，并确定结构振动如何影响铜管乐器的声音。 乐器的研究对本科生来说很有趣，因此，在这一领域进行研究计划自然会吸引年轻人。虽然所研究的系统涉及乐器，但研究的中心是研究并非音乐声学所独有的基本物理现象。因此，学生通过他们发现迷人的主题被引入重要的科学研究。
