The 1-D reflection of an arbitrary incident acoustic wave at an impedance wall is studied, resulting in the formulation of necessary conditions for physically possible impedance models. These results are applied to the problem of an impedance of Helmholtz resonator type, in which case the reflection of an incident pulse is obtained in explicit form, expressed in generalized Laguerre polynomials.
