The Helmholtz Huygens Integral

  • Eugen Skudrzyk


The sound intensity inside a given volume is determined by the power of the sound sources inside this volume and by the sound intensity that enters the volume from outside. It is apparent that the expression for the sound field will be determined by the contributions of the sources and by boundary terms, which represent whatever is reflected at the boundaries or enters through the boundaries from outside. In deriving a formal solution, Green’s formula and Gauss’ theorem are of particular importance.
