Definitions

  • the invention relates to a method for the configuration of setting options on a hearing aid, as may be provided, for example, for adaptation to different hearing situations, and a hearing aid, by means of which this method can be performed.
  • Hearing aids are intended to enable hearing-impaired patients to have the most natural hearing possible and, in the first place, to largely compensate for medically-induced functional disorders of the hearing organs. At the same time, comfort requirements must be taken into account to an increasing extent.
  • the task of a hearing aid is to convert applied sound pressure into a hearing sensation of the hearing aid wearer, which would also occur in the case of physiologically and anatomically intact hearing organs.
  • the hearing aids must therefore be able to be adapted to numerous subjective and objective conditions. These conditions relate to the individual peculiarities of the respectively existing hearing impairment, the selectivity of the perception of the hearing device wearer, but also changing hearing situations or environmental influences which can act on a hearing aid wearer.
  • Modern hearing aids generally have the option of setting a multiplicity of parameters which influence the transmission and amplification characteristics of the hearing device used in each case.
  • the setting of these parameters is initially made by the manufacturer in the form of a basic setting, which can then be adjusted in one or more sessions with a hearing care professional on the patient in the form of a fine adjustment.
  • a fine tuning is associated with a considerable effort, on the one hand for the patient, but on the other hand also for the hearing aid acoustician involved, which is often perceived by the patient as annoying.
  • Hearing aids have therefore been established in which at least part of the adaptation and / or Fine tuning of the hearing aid can be made independently of a hearing care professional, which is preferably done by the hearing aid wearer itself, for example, using a remote control.
  • the problem addressed is particularly true when the individual adjustable parameters simultaneously form the input variables of complex signal processing algorithms, which in turn have an influence on the transmission and amplification characteristics of the hearing aid.
  • Such algorithms can be implemented, for example, for the suppression of background noise or for highlighting desired sound sources in hearing aids. Examples of this are algorithms for setting the directional characteristics, algorithms for damping non-speech components, for fast spectral noise estimation, for wind noise suppression and many more.
  • the number of setting options automatically increases the risk of incorrect settings. This is especially true if the individual adjustable parameters do not affect the transmission and amplification characteristics of the hearing aid completely independently and / or ambiguities arise.
  • a hearing aid wearer it is also known to train a hearing aid wearer so that he can better serve the hearing aid with its functions.
  • a second audio test signal is output, which is changed with respect to the first one.
  • the hearing aid wearer selects one or a plurality of available audio process parameters from which it is deemed that this audio process parameter is most appropriate to match the second audio test signal to the first one varies the selected audio process parameter accordingly.
  • it tests how well the hearing aid wearer was choosing his or her correct audio process parameters and how successfully he matched the second audio test signal to the first one. This is done by comparing what the hearing aid wearer has selected and what to expect from it, with a corresponding value being formed ( WO 2007/113339 ).
  • the object of the invention is therefore to provide a way to be able to adapt a hearing aid to as many, even unpredictable listening situations and to minimize the risk of incorrect settings or mismatches, even if they are made by a non-specialist.
  • the object of the invention is achieved by a method for the configuration of at least one adjusting device on a hearing aid, according to claim 1; and by means of a hearing device for generating an output signal for a hearing aid wearer, according to claim 11 solved.
  • the invention is based on the fact that it is expedient for a safe implementation of adjustments to a hearing aid or the successful use of special features in hearing aids is to estimate beforehand whether the respective user can take advantage of the adjustment or the respective feature at all. As a result, it can be clarified beforehand, in particular with interactive features, whether the user, who would make the relevant adjustments, tends to worsen the setting of the hearing device by his manipulations, or at least to change it in a non-reproducible manner.
  • the following is mainly spoken of adjustments of parameters. However, all possibilities of influencing the mode of action and / or characteristics of a hearing aid, ie switching on, switching off and setting various features and algorithms for signal processing, are also included.
  • the essence of the invention is to identify such adjustment of a hearing aid that can not be used effectively by the respective wearer of a hearing aid. This may be due to the fact that a hearing aid wearer perceives the effectiveness of an adjustment of a parameter or a parameter set as too low or can not quantitatively evaluate this effectiveness, whereby it is impossible for him to determine a respective trend for an adjustment to be made it would lead to perceptible improvement in the transmission and amplification characteristics of the hearing aid.
  • these adjustment options are disabled, ie instead of an adjustable parameter or parameter set, fixed reference values are used as input parameters, which reduces the number of remaining setting options.
  • the determination of the reference values may also include the switching off of certain features whose use for the respective hearing aid wearer is associated with no advantage.
  • the invention consists in a method for configuring at least one adjusting device on a hearing aid, in which a hearing aid wearer is set to adjust the hearing aid by ear with the aid of the adjustment possibility to be configured so that a predetermined characteristic is established on the hearing aid, wherein the adjustment possibility is released when the set by the hearing aid wearer characteristics of the predetermined characteristic is equal to or deviations from this, which are within a predetermined tolerance range.
  • a predetermined characteristic is established on the hearing aid
  • the adjustment possibility is released when the set by the hearing aid wearer characteristics of the predetermined characteristic is equal to or deviations from this, which are within a predetermined tolerance range.
  • the same characteristics will often occur when the adjustment possibilities tested are those adjustment possibilities that are carried out in discrete setting steps. Since it is generally not possible to reproduce absolutely identical settings with continuously variable manipulated variables, a corresponding tolerance range must be defined, the observance of which allows the task to be regarded as solved.
  • the hearing aid wearer qualifies as a candidate for the use of the adjustment possibility to be configured on his hearing aid.
  • characteristic of the hearing device is to be understood as meaning the entirety of the acoustically perceptible properties of the hearing aid, at least some of which can be varied via settings to be made.
  • the hearing aid for performing the method according to the invention is first operated with a fixed reference value of this parameter, which is selected in accordance with a respectively applied auditory situation such that an adjustment of this Parameters objectively a high effectiveness of this adjustment entails.
  • the hearing aid wearer is allowed to perceive a sound example.
  • the reference value of the parameter is replaced by a different value of the parameter and the hearing aid wearer set the task to return the adjustable parameters by ear to the reference value by making appropriate adjustments in the same hearing situation. The quality of this feedback is then evaluated.
  • the amplification and transmission characteristic of the hearing aid can be determined and compared with that which the hearing aid has when it is operated with the fixed reference value of the adjustable parameter. If the two amplification and transmission characteristics are the same or differ only slightly, or if the deviations are below a predetermined threshold value which describes a tolerance range relevant to the relevant release decision, it can be deduced from this that the effectiveness of the tested adjustment possibility lies with the hearing aid wearer can also be perceived subjectively and quantitatively assessed and an adjustability of this parameter for the hearing aid wearer concerned can be released, since the risk of incorrect settings in this case is low.
  • the reference settings can also be directly compared with the parameter settings made by the hearing device wearer and evaluated in the same way, which is particularly advantageous if adjustable parameters can be read out.
  • Fig. 1 shows a flowchart of the method according to the invention using the example of an adjustable parameter.
  • An adjustable parameter is set to a fixed reference value P Ref in a first step.
  • a comparison operation makes a comparison of the incoming signal with the output signal of the hearing aid and stores the result of this comparison in the form of a quantitatively evaluable value on / off Ref .
  • the adjustable parameter P is set to a value which deviates from the reference value P Ref by a ⁇ P.
  • the hearing aid wearer is given the opportunity in a further step to vary the parameter P by making appropriate adjustments, at the same time he is asked to make the variation of the parameter P by ear so that the hearing aid has a gain and transfer characteristic, the as close as possible to that it had when the parameter was set to the reference value P ref .
  • the hearing aid wearer becomes that is, try to add a further element P X to the parameter value deviating from the reference value P Ref by ⁇ P and to reach a target value P target which is as close as possible to the originally set reference value P Ref .
  • the remaining deviation between the reference value P Ref of the parameter and the target value P Target achieved by the hearing device wearer is determined by subtracting quantitatively evaluable values On / Off Ref and On / Off target of both settings in a comparison operation.
  • the determined deviation ⁇ target allows an evaluation of the adjustments made by the hearing aid wearer.
  • a case distinction is made as a function of a predetermined threshold value S. If the deviation ⁇ target is smaller than the predetermined threshold value, then the adjustment possibility with regard to the parameter tested is subsequently released. Otherwise, this adjustment option is disabled and the tested parameter is set to a constant value P const . This may correspond to the reference value P Ref , but may also assume changing values as a function of respectively identified hearing situations and / or hearing programs available in the hearing device. During the procedure described, it is ensured that the hearing situation does not change.
  • the method according to the invention can be carried out using other quantities which can be quantitatively evaluated and which can be assigned to the respective parameter settings. These include in particular the setting states of actuators, the actuation of which the parameter setting is realized and which can usually be easily read or read.
  • the illustrated variant using a comparison of the input and output signals in the various settings allows an assessment of the objective effect of procedurally made parameter variation or the tested feature.
  • objective effectiveness of the method according to the invention are both technically detectable influences on acoustic hearing aid features as well as objective tests such as Understand speech intelligibility tests.
  • the method according to the invention always comprises an interactive determination of a subjective effectiveness of an examined parameter adjustment or adjustment. If this deviates strongly from the objective effectiveness in the sense of a technically demonstrable influence on the acoustic properties of the hearing aid, then this deviation can be made the basis of the decision about a release or blocking of the possibility of adjusting the respective parameter.
  • the inventive method thus provides the opportunity to test the effectiveness of a parameter or the effectiveness of its adjustment and to make this test result to the basis of a release decision. This is done without having to estimate and utilize data from a sound audiogram, the age of the hearing aid wearer or other soft factors.
  • Fig. 2 shows a schematic representation of a hearing aid, which is suitable for carrying out the method according to the invention is.
  • This comprises a signal transmission path consisting of an input unit 1 in the form of a microphone, a signal processing and / or amplification unit 2 and an output unit 3 in the form of a loudspeaker. Signals incoming to the microphone can be transmitted to the output unit 3 to a greater extent.
  • one or more signal processing units comprises, in Fig.
  • the further signal processing units 4, 5, 6, 7 are shown, in which incoming signals can be changed by a specific algorithm before they are again the signal processing and / or amplifying unit 2 and fed into the signal applied to the output unit 3 signal ,
  • the further signal processing units 4, 5, 6, 7 may be applied in terms of hardware, be implemented separately or as part of the signal processing and / or amplification unit 2 and / or consist only in the provision of a corresponding signal processing software. This can be disregarded for the functioning of the hearing aid according to the invention.
  • the different algorithms in the signal processing units 4, 5, 6, 7 may, for example, include algorithms for different forms of noise suppression but also all other forms of signal processing that are sought in hearing aids.
  • one or more control elements are included, in Fig. 1
  • four such further control elements 8, 9, 10, 11 are shown, via which one or more parameters, on which the effectiveness of the respective algorithm depends, can be varied.
  • the adjusting elements 8, 9, 10, 11 can be individually enabled or disabled, which is equivalent to a blocking or release of influence on the respective parameters to be adjusted.
  • a reference generator 12 is included, which instead of the parameters which can be set via the adjusting elements 8, 9, 10, 11, respectively generate a reference value P Ref or different constant values P const and can apply them to the corresponding signal processing units 4, 5, 6, 7 ,
  • the method according to the invention for the individual algorithms Alg 1 to Alg n was executed, wherein for the algorithms Alg 1 and Alg 3 a release of the corresponding adjustment was set, while for the remaining algorithms such a release has been denied (dashed connection of the Adjusting elements 9, 11).
  • the hearing aid wearer was therefore unable to use the adjusting options that can be carried out with the adjusting elements 9, 11 in such a way that, according to the method according to the invention, a targeted return of the adjusted parameters to the required reference value P Ref could be achieved.
  • this feedback could be successfully performed.
  • constant parameter values are applied, which can correspond to the reference values P Ref required for carrying out the method as output values of the reference generator 12, but also alternating constant values P const as a function of respectively identified auditory situations and / or in the hearing aid available hearing programs.
  • constant parameter values are applied, which can correspond to the reference values P Ref required for carrying out the method as output values of the reference generator 12, but also alternating constant values P const as a function of respectively identified auditory situations and / or in the hearing aid available hearing programs.

Different configurations can be linked to different listening situations or listening programs. Basically, an inventive release or blocking of adjustment of a hearing aid can be timely to its delivery to the intended hearing aid wearer in a session at the hearing aid acoustician. There you can simulate listening situations and sound examples under laboratory conditions generated that are optimally tuned to assess the hearing instrument wearer's abilities to use certain features and adjustments.
