Rayleigh integral acoustics
WebAcoustics is the science of sound and has particular applications in sound reproduction, noise and sensing [1,2]. Acoustics may be interpreted as an area of applied mathematics [1,3]. In special cases, the mathematical equations governing acoustic problems can be solved analytically, for Webthe seismic field propagation than the simple acoustic wave equation. Our method uses the Kirchhoff and Rayleigh integral formulas for elastic wavefields. Consider-ing that the elastic model approximates the propagation of the seismic fields in the geological media better than the acoustic model, the developed approach can signif-
