Acoustic Propagation in the Near‐Surface Martian Atmosphere
Journal of Geophysical Research: Planets, Volume 129, Issue 7, July 2024.Abstract This work introduces a comprehensive model of sound propagation on Mars, in light of the recent operation of several microphones on the Martian surface. The main outcome of this work is an operational acoustic model capable of simulating the sound field created by any source, at any location on the Martian surface, at any time.
