ABSTRACT

3-D numerical simulation of acoustic pulse propagation in atmosphere toward the ground boundary is performed. The location of the source at the some height over the ground surface, the uniform atmosphere and the smooth stratification by air density are included into the simulation. The visual imagines of the pressure spatial distribution over the wave front of the acoustic pulse are presented and discussed. The results may be used to increase the efficiency of the seismic waves being generated for the investigations of the Earth entrails.

Key words: acoustic pulse, stratification, atmosphere, computer simulation, sound propagation
