Abstract

The problem of acoustic radiation propagation through a lower 500-m plane-stratified turbulent atmospheric layer has been solved by the Monte Carlo method. Statistical estimates of the contribution of multiply scattered radiation to the transmitted acoustic radiation intensity are obtained. A point omnidirectional source of monochromatic acoustic radiation was placed at a height of 35 m above the absorbing Earth’s surface. Statistical estimates of the contribution of multiply scattered radiation to the transmitted radiation intensity have shown that it does not exceed 15% for the outer scale of atmospheric turbulence L0 = 10 m and sound frequency F = 1700 Hz, reaches 30% for L0 = 20 m, and increases to 90% for L0 = 80 m. A comparison of the calculated results with the available experimental data demonstrates their satisfactory agreement.
