1. Low Frequency Acoustic Vibration

   Linked via "terrestrial topographies"

   Physical Characteristics and Propagation
   LFAVs are characterized by extraordinarily long wavelengths, often extending kilometers in atmospheric conditions. This long wavelength results in minimal dissipation over distance, allowing significant energy to persist across terrestrial topographies. Unlike higher frequency sound waves which are readily scattered by minor impedance mismatches, LFAVs tend to diffract around large obstacles, such as mountain ranges or large bu…
