电磁环境是由人为和自然源产生的电场和磁场组成的。介绍了一种通过测量∼10~24000 Hz频率范围内的电场来探索电磁环境的初步实验。进行实验所需的设备包括一台用于数据采集的笔记本电脑和用于电场天线的日常用品。为了说明起见,文中给出了一些测量结果,并讨论了记录对不同实验装置的灵敏度。通过将电场测量与音频记录进行比较,以弥合可感知和不可感知世界之间的差距,从而促进对电磁环境的直观理解。
The electromagnetic environment is composed of electric and magnetic fields which result from man-made and natural sources. An elementary experiment is described to explore the electromagnetic environment by measuring electric fields in the frequency range from∼ 10 to 24 000 Hz. The equipment required to conduct the experiment consists of a laptop for the data acquisition and everyday items for the electric field antenna. Some measurements are presented for illustration, and the sensitivity of the recordings with respect to varying experimental set-ups is discussed. An intuitive understanding of the electromagnetic environment is facilitated by comparison of the electric field measurements with audio recordings to bridge the gap between the sensible and the non-sensible world.
