Abstract

Measurement of radio noise levels were carried out at several field locations (which also included industrial areas), in and around the city of Delhi (28Degree 35'N, 77Degree5'E) by an objective method using a portable equipment (Noise and Field Intensity mater- model NF-105 manufactured by the Empire Devices Products Corp., New York). Noise level values for the frequency band 150Kc/s to 21M/c were obtained during the month of July (1958), when the atmospheric levels usually have maximum values during this period of the year. Tables of Noise levels are given both in field strength values in micro volts/meter per Kc. bandwidth as well as in Noise Power in db above kTB. The results obtained indicate that the noise grade figures for this area need revision
