An Analysis of Metropolitan Incidental Radio Noise Data

Multiple sets of incidental man-made radio noise data assembled from many sources are examined to determine their variation with frequency and distance. Separate treatments are provided for both average noise power and quasipeak noise field intensity data. The frequency and distance variations of average noise power are examined within the intervals 500 kHz to 1 GHz and 1 to 23 miles from an urban center. At several urban separation distances the frequency dependence of quasi-peak noise field intensity is presented for a large portion of the frequency interval between 15 kHz and 400 MHz.
