Definitions

  • the invention relates to a device for adapting programmable hearing aids, comprising a data processing unit that can be coupled to the hearing aid via a signal transmission, into which data characterizing the hearing loss of the hearing device wearer to be supplied can be entered and wherein the data processing unit can also be supplied with characteristic data of the hearing aid or can be called up from a data carrier of the data processing unit .
  • the object of the invention is to provide a device for adapting programmable hearing aids, which enables the best possible adaptation of the hearing aid to the hearing loss, the adaptation itself being simple to carry out and the hearing device-specific properties being optimally usable, taking into account rules which can be specified by the hearing device manufacturer.
  • the data processing unit has a fuzzy logic module, the processor of which processes the input and / or retrievable data and characteristic data, including processing rules, from at least one rule base according to the principle of fuzzy logic, and provides hearing aid setting data as a result.
  • the hearing care professional is given the opportunity to adapt the hearing aid by having a programming unit implemented according to the principle of fuzzy logic, which, after inputting the audiometric data and the type of hearing aid to be adapted, proposes optimal and sensibly coordinated settings of all hearing aid parameters . These suggested settings can be taken over completely or modified if necessary after further acoustic measurements.
  • the fuzzy logic module or the data processing unit is e.g. primarily supplied by the hearing aid manufacturer.
  • the rule set of the module can be supplemented by the user of the adaptation device in such a way that further processing rules for determining the hearing aid parameters can be entered into a data carrier of the module, which are based on the acoustician's special experience.
  • the device according to the invention shown schematically in FIG. 1, for realizing a fuzzy logic system for determining the adaptation parameters for a programmable hearing aid 2 can be implemented in the form of an independent programming device or in combination with a personal computer or in connection with another data processing system.
  • the device comprises a data processing unit 3 which can be coupled to the hearing aid 2 via an interface 12 for signal transmission 1.
  • the signal transmission 1 can take place via a line connection or also wirelessly.
  • the data processing unit 3 or a programming device external to the hearing aid 2 has a fuzzy logic module 5.
  • This module 5 in turn comprises an arithmetic unit 6 or a processor with components for executing the fuzzy logic operations: fuzzification 13, inference formation 14 and defuzzification 15.
  • the fuzzy logic module 5 contains at least one rule base 7.
  • Processing basis for determining hearing aid setting data is stored in a rule base 7 or this set of rules, the data 4 characterizing the respective hearing loss of the hearing aid wearer to be supplied and the characteristic data 11 of the hearing aid 2 to be programmed in each case to be determined for determining the hearing aid setting data / hearing aid parameters in the determination or Calculation of the hearing aid setting data are included.
  • the data 4 relating to the hearing loss of the hearing impaired is entered via an interface 8 to the computing unit 6 of the data processing unit 3 or of the fuzzy logic module 5.
  • the hearing device-specific characteristic data 11 denotes a data carrier for the hearing device-specific characteristic data 11, which is also the data processing unit 3 or is assigned to the fuzzy logic module 5 and the hearing device-specific ones specified by the hearing device manufacturer Characteristic data 11 can be supplied to the computing unit 6 or can be called up by the latter.
  • an additional rule base of the hearing aid acoustician is provided, the data carrier 10 of which gives the hearing aid acoustician the possibility of additional storage of processing rules which are derived from personal experience.
  • the acoustician who adapts the hearing aid can determine, change, or correct the processing rules that can be read into the data carrier 10, while the processing rules of the first rule base 7 specified by the manufacturer should not be changeable.
  • the disadvantage of this procedure is that, in the first case, the individual adaptability of the programmable hearing aid is not used at all, or in the second case, despite great adaptation effort, the hearing aid parameters may not be set optimally or even incorrectly.
  • the structure of processing sizes using fuzzy logic is shown as an example.
  • the first step in implementing a fuzzy logic structure is to define the linguistic variables for their input and output variables. For each of these quantities, their terms are plotted on a numerical scale.
  • the variable size A is shown in units above a numerical value scale over the x axis of the coordinate system. The degree of membership is indicated in the y-axis.
  • the "sharp" value A 2 on the numerical value scale activates, for example, the term “A is very small” with a degree of 0.6 and the term "A is medium” with a degree of 0.2.
  • ⁇ is the "degree of fulfillment" or “degree of truth” of the respective statement.
  • FIG 4 illustrates in graphic form the functioning of this fuzzy logic system:
  • the two sharp input variables A and B are fuzzified in the manner described above.
  • the two operators and and or are implemented in the most common way as minimum and maximum formation.
  • Other types of realization generally known from the literature could in principle also be considered for this.
  • the degree of fulfillment of the linking operations now activate the terms of the fuzzy output variables to the respective extent.
  • Known methods can be used to implement this last step (defuzzification).
