一个学生设计的实验，测量作为高度函数的声速
A student designed experiment measuring the speed of sound as a function of altitude
摘要：
麦克尼斯州立大学的一组学生利用相对便宜和容易买到的设备（如数字录音机、MP3便携式扬声器和系针式麦克风）测量了大气中作为高度函数的声速。该实验作为有效载荷（在NASA资助的学生项目La-ACES的背景下）在高空气球上进行，最高高度达到101，000英尺。尽管存在大量的环境噪声，但我们的特殊实验设计允许将信号从噪声中过滤出来，从而实现卓越的准确度和精度。然后利用声速测量来确定大气主要分子成分（双原子氮和氧）丰度的限度。贝叶斯分析用于对我们的限度的不确定性设置有意义的值。根据我们的经验，学生们发现这种概率方法直观而吸引人。
英文摘要：
Relatively inexpensive and readily commercially available equipment (such as digital recorders, MP3 portable speakers and tie-pin microphones), allowed a team of students from McNeese State University to measure the speed of sound in the atmosphere as a function of altitude. The experiment was carried as a payload (in the context of a NASA funded student program called La-ACES) on a high altitude balloon that reached a maximum altitude of 101,000 feet. Not withstanding substantial environmental noise, our particular experimental design allowed for the filtering of the signal out of the noise, thus achieving remarkable accuracy and precision. The speed of sound measurement was then used to set limits on the abundances of the main molecular components of the atmosphere (diatomic nitrogen and oxygen). Bayesian analysis was used to set meaningful values on the uncertainty of our limits. It is our experience that students find intutive and appealing this type of probability method.
