  • METHOD OF CALIBRATING AN INFRASOUND DETECTION APPARATUS AND SYSTEM FOR CALIBRATING THE INFRASOUND DETECTION APPARATUS
    Publication number: 20150160333
    Abstract: In order to calibrate an infrasound detection apparatus including a sound pressure measurement device, a background noise removal device, and a ground vibration velocity measurement device, a step of generating an artificial seismic wave using an artificial seismic source at a position that is spaced a specific distance from the sound pressure measurement device, a step of measuring an atmospheric pressure change and a ground vibration velocity caused by the artificial seismic wave, and a step of comparing the atmospheric pressure change value measured by the sound pressure measurement device with a theoretical atmospheric pressure change value may be performed.
