Abstract
A hearing assistance system for delivering sounds to a listener provides for subjective, listener-driven programming of a hearing assistance device, such as a hearing aid, using a perceptual model. The system produces a distribution of presets using a perceptual model selected for the listener and allows the listener to navigate through the distribution to adjust parameters of a signal processing algorithm for processing the sounds. The use of the perceptual model increases the potential of fine tuning of the hearing assistance device available to the listener.
Claims38
A hearing assistance system for delivering processed sound to a listener, comprising:
- a controller configured to produce a distribution of a plurality of presets in an N-dimensional space using a perceptual model, the plurality of presets including predetermined settings for a plurality of parameters of a signal processing algorithm, the perceptual model providing for a prediction of one or more qualities or features of the processed sound perceived by the listener for each individual preset of the plurality of presets.
A method for fitting a hearing assistance device that delivers processed sound to a listener, comprising:
- producing a distribution of a plurality of presets in an N-dimensional space using a perceptual model, the plurality of presets including predetermined settings for a plurality of parameters of a signal processing algorithm, the perceptual model providing for a prediction of one or more qualities or features of the processed sound perceived by the listener for each individual preset of the plurality of presets;
- receiving N-dimensional coordinates representative of a position in the N-dimensional space selected by the listener using a user interface;
- mapping the N-dimensional coordinates into selected values of the plurality of parameters;
- and
- processing an input sound signal to produce an output sound signal to be delivered to the listener by executing the signal processing algorithm using the selected values of the plurality of parameters.
