چكيده فارسي :
Sound wave propagation in argon gas is simulated using molecular dynamics (MD) to determine the attenuation of acoustic energy at high frequencies. This study shows the effect of sound source and reflector wall structure on sound parameters in a system containing argon gas. This approach shows that using structurless wall instead of a real wall does not significantly change the results for sound components and the resulting sound velocity value is closer to the experimental data.
