The electromagnetic noise spectrum extends from below 1 cps to above 3,000 mcs. Within this spectrum many phenomena of atmospheric noise have been observed. Those atmospherics which occur in the audio frequency region of the spectrum have been given not only descriptive but also subjective names by many different investigators. As a result, it is often difficult to determine from the literature what aspect of the noise phenomenon is being considered. In addition, references to low frequencies involved in certain experiments are vague. A brief history of atmospherics research is presented here in order to explain the terminology, to show the frequencies involved, and to give some indication of the many aspects of atmospheric noise.
