This paper suggests an expression of a residual-based a posteriori error estimation for a Galerkin ยฎnite element discretisation of the Helmholtz operator applied in acoustics. In the ยฎrst part, we summarise the ยฎnite element approach and the a priori estimates. The new residual estimator is then for
