    • Abstract
  • The finite element formula of sound field, in which there are sound sources and of which the boundary is non-rigid and absorbent, can be worked out by the weighted residual method. The formulae of characteristic value problem of sound field, which has been deduced using variational method[1], may be taken as a particular case.
