  • Abstract
    In this investigation the warbler method was followed in measuring the atmospheric noise at Dacca during the month of June within the range of frequencies from 250 to 1500 kilocycles. Attention was directed to (1) the study of high-frequency atmospheric noise (both day and night) as a function of frequency, and (2) the study of the diurnal characteristics of high-frequency atmospheric noise with special reference to the sunrise and sunset times.
