Wind Noise Suppression for Infrasound Sensors
Abstract
The porous hose and pipe arrays often used for wind noise suppression in long-term infrasound monitoring arrays can be tedious to install and can significantly alter the signals reaching the infrasound sensors. An ideal windscreen, over the frequency band of interest, should preserve all of the characteristics of desired signals that reach the sensor, while removing all of the wind-generated noise. In order to improve upon current state-of-the-art infrasound windscreens, two porous and one non-porous fabric domes were investigated for use as infrasound wind screens. Both of the porous domes perform well in preserving signal information and in consistently reducing wind-generated noise reaching the sensor.
