The popular compact disk entitled Auditory Demonstrations, sponsored by the Acoustical Society of America, includes a number of demonstrations that lead to quantitative results. Those demonstrations are evaluated here in the context of a sizeable class in a lecture room. Demonstrations concern masking, loudness, and pitch; specifically they are numbers 2, 3, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 20, and 25. The evaluations find that most of the demonstrations successfully illustrate psychoacoustical principles in a classroom context; others are less successful or require special circumstances for success. Explanations for success and failure are offered, together with some suggestions for optimizing the chances of success.
由美国声学学会赞助的热门光盘《听觉演示》包含许多能得出定量结果的演示。在此，我们在一间阶梯教室的大量学生的背景下对这些演示进行评估。演示内容涉及掩蔽、响度和音高；具体来说，是编号为2、3、6、7、8、9、10、11、12、14、15、16、17、20和25的演示。评估发现，大多数演示在课堂环境中成功地阐明了心理声学原理；其他演示则不太成功，或者需要特殊情况才能成功。文中给出了成功与失败的原因，并提出了一些优化成功几率的建议。
