Definitions

  • the present invention relates to a method for adapting a hearing device by providing evaluation data for different, predetermined listening situations and adapting the hearing device to a hearing device wearer by means of individual weighting.
  • the present invention relates to a corresponding device for adjusting a hearing aid and an individually adjustable hearing aid.
  • a hearing aid which the user can set menu-driven individually. By lightly touching a control pad, the user gains access to a new parameter set for a specific response function, which is then input to a digital signal processor. By means of a few touches, the user can find the answering function appropriate to his acoustic environment and the required gain.
  • a programmable digital hearing aid system is known. By programming, the electro-acoustic properties of the hearing aid can be adapted to the patient and the environment. Selected parameter values are loaded into programmable memory (EEPROM) which provides corresponding coefficients to a programmable filter and amplitude limiter of the hearing aid so as to achieve automatic adjustment for ambient noise, speech levels and the like.
  • EEPROM programmable memory
  • the hearing aid adjusts itself with his hearing aid parameters to a hearing situation that is currently not available.
  • the audio signals are transmitted to the hearing aid wearers inappropriate. For example, if the listening situation "language at rest” with the Hearing situation "music” confused, so under certain circumstances unnecessary or disturbing frequency components are transmitted or certain frequency components improperly amplified.
  • the object of the present invention is therefore to improve the adaptation of a hearing device to a current hearing situation.
  • this object is achieved by a method for adapting a hearing device by providing evaluation data for various predetermined hearing situations and fitting the hearing device to a hearing device wearer by means of individual weighting, wherein the individual weighting is performed by a continuous weighting function passing through interpolation points, each of which is an individual Weighting of the evaluation data represent one of the given listening situations.
  • the hearing device parameters can thus be continuously adapted to different listening situations.
  • the abrupt change of a complete hearing device parameter set can thereby be avoided, so that a current auditory situation does not have to be discretely assigned to a predetermined class.
  • the evaluation data are determined offline in advance by a sound signal analysis.
  • a database having multiple evaluation data for a plurality of listening situations can be constructed as bases for a continuous function.
  • the evaluation data may include weight vectors with respect to specific audio signals that are characteristic of the given listening situations. Such weight vectors can advantageously be determined by an eigenvector analysis of the specific audio signals.
  • the weighting function for the individual weighting can be determined from listening situations characteristic of the hearing aid wearer.
  • listening situations characteristic of the hearing aid wearer it is possible to deal specifically with the habits of the hearing aid wearer and those hearing situations that occur during the hearing him most frequently used as a basis for the adjustment of the hearing aid.
  • the weighting function is conveniently determined from at least one fitting parameter and at least one value of the evaluation data. To refine the individualization of a hearing device, it is also possible to use a plurality of values of the evaluation data for obtaining the weighting function.
  • the method for adapting a hearing device to a hearing device wearer or his hearing loss includes two offline methods and one real-time method.
  • a plurality of typical audio signals are analyzed for characteristic evaluation data.
  • a fitting function that is individual for a hearing device wearer with the characteristic evaluation data is obtained as a parameter.
  • the hearing aid is adjusted individually for a current hearing situation.
  • step 11 M signal characteristics that may be altered by the digital signal processing of the hearing aid are defined.
  • step 13 the characteristics of the audio signals collected in step 12 are determined.
  • the feature correlation is determined individually (a) and total (b) in step 14. This results in the correlation matrices C a and C b .
  • step 15 the eigenvectors corresponding to the generic listening situations and the intrinsic features of the correlation matrices C a and C b are determined by diagonalizing. Furthermore, the normalized eigenvalues (statistical weights) are determined for the subsequent fitting process.
  • the speech feature vector V max and generic feature vectors V gi are determined.
  • the speech feature vector V max corresponds to the C a eigenvector for "speech at rest" having the highest eigenvalue.
  • the generic feature vectors V gi represent the n C b eigenvectors with the highest eigenvalues with which, for example, 95% of all audio signals can be restored.
  • the offline sound signal analysis are thus determined by correlation of the individual features, such as modulation depth, modulation frequency, energy in a frequency band, etc., the main features or main eigenvectors typical listening situations.
  • the weights of the main features represent, as already mentioned, about 95% of the sum of all weights, so that the other features are negligible.
  • the offline fitting analysis serves on the one hand to determine an individual base adjustment, z.
  • the hearing aid fitting which judges a particular hard of hearing person as optimal for speech at rest.
  • the offline fitting analysis is used to determine the required parameter changes depending on the mixing ratio of the generic listening situations.
  • the result is a functional relationship between the mixing parameters of a given hearing situation and the individual and optimal hearing aid parameters for this situation.
  • the advantage of this is that the hearing aid parameters that are suitable for a hearing situation are determined individually for the hearing aid wearer and can be changed fluently in fluent transitions of hearing situations, since the functional relationship was determined.
  • This procedure should be implemented in the hearing aid fitting software because the function that maps the mixing parameters to the hearing aid parameters must be determined with the fitting software and programmed into the hearing aid.
  • the individual hearing loss of a patient is taken into account in the offline fitting or fitting analysis as follows.
  • the patient is first interviewed in step 20 for characteristic hearing situations in his social environment. Here he calls those listening situations that have the most importance for him or occur most frequently such as "speech at rest", “phone calls”, etc.
  • the record x 0 corresponds to z.
  • the audio sample "Language at rest”.
  • step 22 the weight vectors a 0... A n of the selected sound examples are determined. They are taken from the database created during the offline sound signal analysis.
  • the best individual fit with corresponding match parameter vectors is determined according to step 23.
  • the approach of interactive, adaptive fitting is selected for the sound examples.
  • the corresponding fitting or fitting parameter vectors are b 0 ... b n . This step ensures a subjective assessment of typical, objective listening situations.
  • ) or b b 0 + c 1
  • the Taylor coefficients c 1 , c 2 ... can be determined by regression. The determined function, based on one or more coefficients, thus quantizes the relationship between objective hearing situation and subjective perception.
  • the real-time classification or real-time setting of the hearing device makes it possible that upon detection of a specific mixing ratio of generic hearing situations, the corresponding hearing device parameter set is active and the transitions are fluid.
  • the individual function determined in steps 20 to 24 in FIG. 2 is used during the operation of the hearing device for real-time classification according to the method sequence of FIG. 3 used.
  • a main adjustment parameter is used for basic adjustment of the hearing aid.
  • the main adjustment parameter b 0 classifies the hearing situation which is individually most important for the patient.
  • the basis of this determination is the input signal in a time window, with which the feature vector results just for this window.
  • the adjustment vector is finally smoothed in step 34.
  • the device according to the invention or the method according to the invention greatly reduces confusion between detected hearing situations. There is a clear mapping of listening situations to hearing aid parameters as well as an individual classification.
