Abstract
The method and the apparatus specify that the acoustic useful signal is generated from a electrical useful signal, that an electrical listening signal determined by the acoustic useful signal and by an acoustic noise signal at the listening location be recorded, and from this the useful signal component contained therein be extracted. Then the useful signal component contained in the listening signal is compared with the listening signal itself, and the electrical useful signal is adapted in dependence on this.
