A Laboratory for Introductory Musical Acoustics

正在开发一个声学实验室，以纳入为期五周的音乐声学强化课程。非理工科学生是主要的目标受众。24名学生每周五天开会，进行两小时的讲座、演示和讨论。学生们每天两人一组完成一个两小时的实验室实验，每组12名学生。在课程的前两周，我们将开展实验来介绍力学概念，包括振动和波，这是理解声学现象所必需的。共振在机械和声学系统是一个主要的焦点，使用仪器，如光门定时器，示波器，麦克风，函数发生器和声级计。各种仪器和声音发生器的频谱分析是第二组实验的主题。每个实验室站包括一个快速傅立叶变换频谱分析仪进行实时分析，一个高品质的麦克风与前置放大器，和绘图仪。这些电台可以让学生在定量的细节上探索广泛的声学现象。在独立的学生项目中使用所获得的技术。该设备还提供了高级论文的机会。

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.
