The process of near-ground propagation of monochromatic acoustic radiation at frequencies of 300, 1000, 2000, and 3150 Hz along atmospheric paths up to 100 m long is investigated experimentally and theoretically depending on altitudes of acoustic source and receiver. Experiments were performed at the experimental site of the IMCES SB RAS using a specially developed setup. The dependence of the recorded sound pressure level on the propagation path length and the initial signal power is studied. The theoretical analysis is performed by the Monte Carlo method that allows contributions of multiple scattering of acoustic radiation, refraction, and reflection by the underlying surface to the acoustic signal recorded with the detector to be taken into account for realistic models of the atmosphere. The local estimation algorithm of the Monte Carlo method developed by the authors was used for calculations. The comparison of the experimental and theoretical results shows their satisfactory agreement, which testifies to the efficiency of the suggested Monte Carlo algorithm and its applicabilty to the prediction of near-ground acoustic radiation propagation.
