Definitions

  • the invention relates to a method and a device for setting a characteristic of a hearing aid on another hearing aid, in particular after the replacement of an old hearing aid by a new hearing aid.
  • Hearing devices usually have a variety of settings to allow the wearer of a hearing aid natural hearing possible or to incorporate individual preferences of the hearing aid wearer in the setting of his personal hearing aid.
  • the setting of a hearing aid is usually initially carried out in the form of a specification of a parameter set, which can be matched only relatively roughly to the expected requirements of the hearing aid wearer.
  • fine tunings take place at short intervals, which lead to an improved parameter setting and are either made in several consecutive sessions at a hearing care professional or carried out by the hearing aid wearer with the aid of certain optimization algorithms themselves.
  • a hearing aid wearer in particular a person with hearing loss, thereby becomes accustomed to the transmission properties of his hearing aid on a continuous basis, which affects in particular the sound of the hearing aid, but also various implicit signal processing algorithms and their effect.
  • the replacement of a hearing aid is required. This can be given, for example, by a deterioration or change in the hearing of the hearing aid wearer, other exemplary situations can be found after technical defects of the hearing aid to be replaced or a desire for now available comfort features and / or otherwise increased Functional variety of modern hearing aids.
  • the change of a hearing aid always entails the danger that the hearing aid wearer perceives the sound of the new hearing aid as unfamiliar and unfamiliar due to the habituation to the old hearing aid that has hitherto been carried out and then possibly rejects the change of the hearing aid.
  • the analysis of the first hearing device can be performed metrologically by providing input sound signals and detecting and evaluating output sound signals generated at the hearing device output.
  • This method is relatively expensive, but is applicable to all sound pressure generating hearing aids. In other hearing aids would have to be evaluated instead of the output sound signals other Hörssenforce outputs.
  • the effort for the analysis of the first hearing aid can be reduced if instead of the complete measurement a provision of the existing parameter settings takes place and based on the knowledge of these settings with the help of a corresponding model, a simulation of the characteristics of the first hearing aid is made.
  • the object of the invention is thus to specify a possibility of being able to carry out a largely automated setting of parameters of a hearing aid taking into account a customer request and / or patient request based on a customary hearing device characteristic, even if the complete characteristic of the hearing aid is not known. This should be done with the least possible effort.
  • Claim 8 relates to an apparatus for carrying out the method according to the invention and the claims 9 to 14 relate to advantageous embodiments of such a device.
  • the invention is based on the fact that parameter settings when replacing an original hearing aid, for example an old hearing aid, by a target hearing aid, for example a new hearing aid, are made in the form of a first-fit setting, which can be taken from a transformation database.
  • the installation of this transformation database takes place in such a way that the transmission characteristic of the original hearing device is first determined for a discrete number of parameter sets which can be set on the original hearing aid to be detached.
  • a parameter setting is performed on a target hearing device, which is to replace the original hearing aid, in which each sets an identical or at least similar transmission characteristics of the target hearing aid.
  • the parameters required to achieve these characteristics on the target hearing device are captured and stored in the transformation database.
  • This procedure is repeated for a number of possible target hearing aids that are to be considered for replacement of the original hearing aid to be replaced.
  • the replacement is expected in analogous manner, a data acquisition be made.
  • a transformation database in which prior to the hearing aid exchanged parameter sets are stored, which has led to a desired characteristic depending on the type of original hearing aid to be replaced, the type of target hearing aid and the parameter set or the setting on the original hearing aid to be replaced that was last set, for example.
  • the determination of the parameters to be set on the target hearing aid to obtain a transmission characteristic corresponding to that of the original hearing aid at a particular parameter set may be performed iteratively in a manner known per se or carried out using possibly available modeling techniques on the basis of dynamic or static models.
  • Decisive for the profitability of the method according to the invention is that the number of possible parameter settings which are to be detected by measurement in the manner shown is limited so that the effort for the inventive primary determination of the settings required for a transition from one to another type of hearing aid as the basis of the transformation database remains justifiable.
  • the number of possible combinations of parameters is limited in advance for hearing aids with a limited number of adjustable parameters that can only be varied in discrete steps.
  • the method according to the invention For hearing aids which have adjusting elements with which parameters can be adjusted continuously, it is advantageous for the method according to the invention to divide the setting range into discrete setting steps in order to limit the number of possible parameter combinations to a finite value.
  • the step size of these adjustment options circumstances of a profitable data management, the storage capacity, but also aspects of the perceptibility of certain parameter adjustments or their effect on the transmission characteristic of the hearing aid concerned can be taken into account Find. For example, it can be determined by simple tests as to which absolute or relative value a parameter has to be adjusted in order to lead to certainly perceptible changes in the transmission characteristic of the hearing aid.
  • a step size for carrying out the method according to the invention can be determined, which is further than the step size of the smallest perceptible adjustment, which would average over a typical patient group, since a narrower step size would, for subjective reasons, generally not cause a perceptible improvement in the setting accuracy On the other hand, it would have to disproportionately increase the overhead of data management and data collection.
  • the invention can also be applied if in a transformation database not all possible combinations of Hearing aids and reproducible characteristics in the form of stored records are prepared. There is already considerable benefit if individual, but particularly frequently or with high probability, these combinations are retrievable in the transformation database in the form of the data sets generated according to the invention.
  • To create the transformation database at least one original hearing device U x is acoustically measured at at least one setting C y .
  • At least one target hearing device Z for the setting C (Z z, U x (C y)) is determined, wherein the target hearing device Z z has a characteristic similar to that characteristic which has been determined by the acoustic measurement of the source hearing device U x.
  • This setting C (Z z , U x (C y )) are associated with the type U x of the original hearing aid, the measured setting C y of the original hearing aid and the type Z z of the target hearing aid and stored as a record.
  • the value of the transformation database increases with their database, so the typical approach is that x several different settings C y are measured acoustically to the plant transformation database at multiple origin hearing aids U, at a plurality of objective hearing aids Z z settings C (Z z, U x (C y )) are determined, in which the target hearing aids Z z have a characteristic which corresponds in each case to the characteristic which was determined by the acoustic measurement of the original hearing aids U x , and the parameters of the settings C (Z z , U x (C y )) are linked to the type U x of the original hearing aids, the measured settings C y of the original hearing aids and the type Z z of the target hearing aids and stored as data records.
  • the invention can be used in particular in the repair of damaged hearing aids.
  • damaged hearing aids it is often no longer possible to precisely determine the hearing aid characteristic due to the damage, so that a costly readjustment would be required after the repair.
  • This can be done with the invention Method in which the characteristic can be reproduced via the transformation database, easily solve.
  • Fig. 1 shows a program flowchart of the method according to the invention during the creation of the transformation database.
  • a first step an original hearing device U x is selected, the replacement of which is to be prepared by another hearing aid.
  • a variation of possible settings is made.
  • the individual setting will be referred to below as C y , the settings C y depending on the technical capabilities of the original hearing aid U x , which is why the respective setting can be completely described by U x (C y ).
  • the variety of possible settings results from the number of independently variable parameters or manipulated variables as well as the number of steps in which these parameters or manipulated variables can be adjusted. In the case of continuously adjustable manipulated variables, a division of the Adjustment range in a finite number of discrete steps necessary.
  • a characteristic of the original hearing aid U x is determined in a further step, which describes its acoustic behavior. For this purpose, in particular the transmission and amplification characteristics of the hearing aid are suitable.
  • the selection of a target hearing aid Z z which is considered for the replacement of the original hearing aid U x into consideration. At this target hearing device such a setting of its adjustable parameters or manipulated variables is made by suitable measures, which lead to a characteristic of the target hearing aid Z z , which corresponds to the characteristic of the original hearing U x at the setting C y .
  • Suitable measures which lead to the desired setting on the target hearing aid Z z include different forms of parameter variations, which can facilitate or facilitate a targeted finding of a given characteristic. For this purpose, in particular a continuous measurement of the target hearing device to be adjusted is required in order to be able to understand the effect of the adjustments made.
  • the insignificance of the deviation are set by specifying a tolerance range qualified can, in a further step, the required to achieve this characteristic setting C (Z z , U x (C y )) is read out on the target hearing aid Z z and stored in a transformation database. From this transformation database the setting C (Z z, U x (C y)) can always be read out and find, for use for a presetting of a target hearing device Z, when this target hearing device is intended to replace an origin hearing aid U x with the setting C y.
  • the procedure for collecting the values required for the transformation database is repeated for each target hearing device Z z up to a maximum number Z max .
  • the value Z max is determined, for example, from the number of hearing aid models to be considered that are responsible for a Replacement of older hearing aids come into question. Furthermore, the complete procedure for each of these potentially removable hearing aids for each setting C y to go through and repeating in the eventual replacement of different original hearing aids U x again completely for each of these original hearing aids.
  • the transformation database various settings C (Z z, U x (C y)) found stored in parameterized form in the database, which tested for each change from one type of hearing device U x to another type of hearing device Z z for each setting C y each source hearing device U x U x on the original hearing device replacing target hearing device Z z are set.
  • the effort of data collection is initially comparable with a setting of a hearing aid based on a given characteristic without the use of a database. However, it decreases immediately if an exchange is repeated with appropriate specifications regarding the characteristic and with the same type of hearing aid.
  • transformation database Another advantage of the installation of the transformation database is that it can be largely independent of the hearing aid wearer under laboratory conditions and is already available in prepared form during the actual adaptation of a new hearing aid to the patient. Another advantage of having a transformation database in accordance with the invention is a significant market advantage over hearing aids that are shipped with model-dependent transformation data.

  • the setting C (Z z , U x (C y )) obtained according to the invention can be used as a first-fit setting, from which a metrologically accompanied fine-tuning can be made, but this already significantly reduces the effort for this fine-tuning compared to other methods according to the prior art by the generally small required deviation from the first-fit setting.
