Analysis of the Characteristics of the Background Ambient Noise Origin of Infrasound Station

Abstract

Meteorological elements are the important factors influencing the background noise model of the infrasound station. In order to determine the specific impact of meteorological elements on the model and find out the background ambient noise root of infrasound station, the infrasound and meteorological data from international infrasound station I34 is processed and analyzed through root mean square research and power spectral density analysis. The results show that the wind speed, wind direction, temperature and pressure is the main factors influencing the infrasound station environment background noise, and the wind speed exercises the greatest influence on background noise. Analysis results can provide theory basis for the modeling of background noise for the infrasound station.
