1. A method for manufacturing a hearing device which is adapted to an individual comprising:
- providing a model modeling a psycho-acoustic perception variable from acoustic signals;
setting said model so that said psycho-acoustic perception variable as modeled is at least substantially equal to said psycho-acoustic perception variable as perceived by a standard individual;
further setting said model so that said psycho-acoustic perception variable as modeled is at least substantially equal to said psycho-acoustic perception variable as perceived by said individual;
providing an adjusting apparatus separate from said hearing device and setting said adjusting apparatus as a function of said setting and of said further setting;
operationally connecting an input of said adjusting apparatus to an output of an input converter of said hearing device; and
adjusting a transmission between said output of said input converter and an input of an output converter of said hearing device as a function of an output of said adjusting apparatus, whereinsaid model is provided at said hearing device, feeding a signal dependent on an output signal of said input converter to said model as set and feeding a signal dependent of an input signal to said output converter of said hearing device to said model as further set.

Abstract
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 (LN) as well as for an individual (LI). 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.

8. A method for manufacturing a hearing device which is adapted to an individual, comprising:
-
manufacturing a hearing device generating a first electric signal dependent from acoustic input signals to said hearing device and generating a second electric signal dependent from an output signal of said hearing device; providing a model modeling a psycho-acoustic perception variable from signals representing acoustic signals; setting said model so that said psycho-acoustic perception variable as modeled is at least substantially equal to said psycho-acoustic perception variable as perceived by a standard individual; Further setting said model so that said psycho-acoustic perception variable as modeled is at least substantially equal to said psycho-acoustic perception variable as perceived by said individual; Subjecting said first electric signal to said model as set, thereby generating a first model result; Subjecting said second electric signal to said model as further set thereby generating a second model result; Adjusting signal transmission between said input and said output signals of said hearing device as a function of said first and second model results. - View Dependent Claims (9, 10, 11, 12)
