Relationship between the Parameters of Infrasound Waves and the Energy of the Source

Resumo

Abstract—A new phenomenological model describing the propagation of acoustic disturbances in the stratospheric waveguide is proposed based on instrumental observations of infrasound signals from high-power explosive sources in the atmosphere. A generalized relationship between the energy of the acoustic source in the atmosphere and the characteristic frequency in the spectrum of the acoustic signal is obtained. The developed model is verified against the description of natural and manmade acoustic sources with the known energy. It is shown that the proposed model agrees with the observations and the data obtained in the other works.
