Abstract:
The propagation of acoustic radiation from a point source through the horizontally stratified atmosphere was studied by the Monte-Carlo method. The multiple scattering effect on the transmitted radiation was estimated for different detector zones. For the outer turbulence scales L0 = 20 and L0 = 100 m, the multiple scattering contribution was found to be 10-30% and 70% respectively, for a radiated acoustic frequency of 1 kHz. When the point source was 0.3 m high above the ground the sound radiation absorbed by the Earth's surface was calculated to be 4.3 dB. A comparative analysis showed the estimated data to agree well with the experimental evidence available.
