Fitting procedure for hearing devices and corresponding hearing device
View Patent ↗The method for adjusting a hearing device ( 11 ) to the hearing preferences of a user of the hearing device comprises a) adjusting at least one of N parameters (P 1 , P 2 ), preferably with 2≦N≦4; b) obtaining a gain model (G), which is identical with the output of a fitting rationale (F) applied to a model audiogram (A), wherein the model audiogram depends on the N parameters and is independent of possibly existing audiogram values measured for the user; and c) using the gain model (G) or a gain model derived therefrom in said hearing device ( 11 ). Preferably, the model audiogram (A) is an approximation to an audiogram occurring in a pre-defined empirical sample of individual audiograms. The user preferably carries out the method by himself and without external equipment. A corresponding arrangement ( 1 ) is disclosed, too. A simple and efficient hearing device fitting can be achieved.
1. A method for adjusting a hearing device to the hearing preferences of a user of said hearing device, said method comprising the steps of
a) the user adjusting at least one of N user adjustable hearing device parameters;
b) automatically selecting a model audiogram, the selection being dependent on said N user adjustable hearing device parameters and independent of existing audiogram values measured for said user; and
c) automatically applying a fitting rationale to the selected model audiogram to obtain a gain model for the hearing device.
2. The method according to claim 1 , comprising the step of
d) processing a sound signal in said hearing device according to said gain model or a gain model derived therefrom.
3. The method according to claim 2 , wherein step d) is carried out automatically after step c).
4. The method according to one of the preceding claims, wherein 2≦N≦4.
5. The method according to claim 1 , wherein said model audiogram is an approximation to an audiogram occurring in a pre-defined empirical sample of individual audiograms.
6. The method according to claim 5 , wherein a definition of at least one of said N user adjustable hearing device parameters is derived based upon a statistical analysis of said pre-defined empirical sample of individual audiograms.
7. The method according to claim 1 , further comprising the step of
obtaining data from a look-up table, wherein the data represents characteristics of: the fitting rationale, the model audiogram, or the gain model.
8. The method according to claim 1 , which is carried out using solely devices of a hearing system to which said hearing device belongs.
9. The method according to claim 1 , wherein the model audiogram is selected from a plurality of audiograms stored in a storage unit of the hearing device.
10. A system for adjusting a hearing device to the hearing preferences of a user of said hearing device, comprising
said hearing device;
at least one user control for adjusting N user adjustable hearing device parameters;
a control unit adapted to automatically select a model audiogram, the selection being dependent on said N user adjustable hearing device parameters and independent of existing audiogram values measured for said user; and automatically apply a fitting rationale to the selected model audiogram to obtain a gain model for the hearing device.
11. The system according to claim 10 , which is comprised in a hearing system comprising said hearing device.
12. The system according to claim 10 , which is comprised in said hearing device.
13. A non-transitory computer readable storage medium storing program code for adjusting a hearing device to the hearing preferences of a user of said hearing device, the program code causing a computer to perform the steps of
A) receiving user input indicative of a requested adjustment of N user adjustable hearing device parameters;
B) automatically selecting a model audiogram, the selection being dependent on said N user adjustable hearing device parameters and independent of existing audiogram values measured for said user; and
C) automatically applying a fitting rationale to the selected model audiogram to obtain a gain model for the hearing device.
14. The non-transitory computer readable storage medium according to claim 13 , wherein said computer is comprised in a hearing system comprising said hearing device.
15. The arrangement according to claim 10 , further comprising a storage unit of the hearing device storing a plurality of audiograms from which the control unit selects the model audiogram.
