An acoustics laboratory is being developed for inclusion in a five-week intensive course on musical acoustics. Non-science majors are the primary target audiences. Twenty-four students are meeting five days a week for a two-hour session of lecture, demonstration and discussion. Students working in pairs complete a two-hour laboratory experiment each day, in two shifts of 12 students each. In the first two weeks of the course, experiments are being developed to introduce concepts of mechanics, including vibrations and waves, necessary to understand acoustic phenomena. Resonances in mechanical and acoustic systems are a primary focus, using instruments such as photogate timers, oscilloscopes, microphones, function generators and sound level meters. Spectral analysis of a variety of instruments and sound generators is the topic of the second group of experiments. Each of six lab stations includes a Fast Fourier Transform spectrum analyzer for real-time analysis, a high-quality microphone with preamplifier, and a plotter. These stations allow students to explore a wide range of acoustic phenomena in quantitative detail. Acquired techniques are being used in independent student projects. The equipment is also providing senior thesis opportunities.

正在开发一个声学实验室， 为期五周的音乐声学强化课程 非科学 专业是主要的目标受众。 二十四个学生 一周五天，每次两小时的讲座， 演示和讨论。 学生们结对工作 每天完成两个小时的实验室实验， 每班12名学生。 在头两个星期的 课程，正在开发实验，以引入概念 力学，包括振动和波，必要的， 了解声学现象。 机械和机械中的共振 声学系统是一个主要的焦点，使用仪器， 光电门定时器，示波器，麦克风，功能 发电机和声级计。 光谱分析 各种乐器和声音发生器是主题的 第二组实验。 六个实验站中的每一个都包括 快速傅里叶变换频谱分析仪， 分析，高品质的麦克风与麦克风，和 - 是的 这些车站允许学生探索广泛的 声学现象的定量细节。 收购 技术被用于独立的学生项目。 的 设备也提供高级论文的机会。
