This award supports two experimental investigations into the physics of musical instruments. The two projects represent complex problems involving energy transfer between vibrating structures and the air flow that produces the vibration. One goal is to determine if the vibration of the tubing of brass wind instruments in the direction of the air flow is the primary reason that the material and bracing of the instrument affects the sound. If this is found to be the case, it will answer a question that has been debated in the scientific literature for over a century. The second goal is to determine the physical parameters of a reed that are necessary to construct an accurate model of a clarinet during actual performance. The results of this study will enhance the ability to synthesize the sound of woodwind instruments and provide needed information concerning which parameters musical instrument designers should be adjusting to improve their instruments. The primary goal of the work is to involve undergraduate students, particularly women, in original scientific research. While the systems under study involve musical instruments, the research centers on studying basic physical phenomena that are not unique to musical acoustics. This work contributes to the understanding of some important physics, with both scientific and industrial applications, but more importantly it introduces undergraduate students to original scientific research through a subject they find fascinating.

该奖项支持对乐器物理学的两项实验研究。这两个项目代表了复杂的问题，涉及振动结构和产生振动的气流之间的能量传递。一个目标是确定铜管乐器的管在气流方向上的振动是否是乐器的材料和支撑影响声音的主要原因。如果这是真的，它将回答一个在科学文献中争论了世纪的问题。第二个目标是确定簧片的物理参数，这些参数是在实际演奏中构建单簧管精确模型所必需的。本研究的结果将提高木管乐器合成声音的能力，并提供所需的信息，乐器设计师应该调整哪些参数，以改善他们的乐器。 这项工作的主要目标是让大学生，特别是女生参与原创性科学研究。虽然正在研究的系统涉及乐器，但研究中心研究的是并非音乐声学所独有的基本物理现象。这项工作有助于理解一些重要的物理学，具有科学和工业应用，但更重要的是，它通过一个他们发现迷人的主题向本科生介绍了原创性的科学研究。
