1. A method for configuring signal processing parameters of a hearing assistance device of a listener, comprising: selecting a plurality of signal processing parameters to control; selecting a plurality of presets, including a setting for each of the plurality of parameters, at least one parameter chosen to span at least one parameter space of interest; displaying the plurality of presets on an N-dimensional space; recording the listener's organization of the plurality of presets in the N-dimensional space based on sound heard by the listener from the hearing assistance device processed according to the signal processing parameters at each preset; constructing a mapping of coordinates of the N-dimensional space to the plurality of parameters using interpolation of the presets as organized by the user in the N-dimensional space; generating interpolated signal processing parameters from coordinates associated with a cursor position in the N-dimensional space according to the mapping; and providing the interpolated signal processing parameters to the hearing assistance device.
