METHOD FOR THE ADJUSTMENT OF A HEARING DEVICE, APPARATUS TO DO IT AND A HEARING DEVICE

An adjustment method for a hearing device and an apparatus to do it are proposed, by which a model for the perception of a psycho-acoustic variable, especially of the loudness, is parametrized for a standard group of individuals (L.sub.N) as well as for an individual (L.sub.I). On grounds of model differences, especially in relation to their parametrization, the adjustment values are determined, whereas the signal transmission is planned or adjusted at a hearing device (HG) ex situ or is guided in situ, respectively.
