Man-Made Noise Study at 76 and 200 kHz

A limited study of man-made impulsive noise was made at 76 and 200 kHz. The purpose of the study was to collect data in various locations to be used as noise models for man-made noise simulators. Impulsive noise data were taken of automotive systems, industrial sites, and residential areas. Two classes of noise, both class A and B, are shown and, for comparative purposes, some atmospheric radio noise data are included.
