## Abstract An estimator for the error in the wave number is presented in the context of finite element approximations of the Helmholtz equation. The proposed estimate is an extension of the ideas introduced in Steffens and D'Δ±ez (__Comput. Methods Appl. Mech. Engng__ 2009; **198**:1389–1400). In t
