Rayleigh integral acoustics
WebThe web page gives access to the manual and rimman/codes (open source) that implement the Rayleigh Integral Method. The Rayleigh Integral Method is useful in computing the acoustic properties of a flat panel radiating into a half space. Before downloading the rimman/codes, please join the Linked-in user/developer group . WebAug 1, 2006 · The Rayleigh integral approximation under consideration is enhanced so that only the elements visible to a particular point in the field are used to calculate the sound pressure at that point. It is demonstrated how both the Rayleigh integral and high frequency boundary element method are approximations to the boundary integral equation so that …
