Definitions

  • the invention relates to a method for optimizing the adaptation of hearing aids using natural sound images corresponding to everyday hearing situations.
  • Such methods are suitable for adapting hearing aids to the individual requirements of a hearing impaired person, with the use of natural sound images making it possible in particular to perceive ambient noises as well as speech signals in a natural speech environment.
  • a disadvantage of the known methods is that the hearing impaired person is often not adequately integrated into the fitting process and that the hearing impressions conveyed to the hearing impaired person are not recorded quantitatively and therefore cannot be documented.
  • the method according to the invention causes the hearing impaired person to evaluate his hearing impression after each sound image presented to him acoustically and to enter the result of this evaluation either himself or with the help of the acoustician in a computer.
  • the computer determines the hearing aid parameters to be used in each case on the basis of predetermined algorithms as a function of the entered evaluation and the sound image, so as to achieve an improvement in the hearing impression conveyed to the hearing impaired.
  • the adjustment of the hearing aid parameters on the hearing aid itself can either be triggered directly by the computer via a suitable connection or can be carried out by the acoustician taking into account the result determined by the computer.
  • the hearing impaired person is then presented with the previously assessed sound image again - but now with the newly set hearing aid parameters - whereupon the hearing impression is assessed again by the hearing impaired person. This process is repeated until an optimal setting of the hearing aid has been found iteratively.
  • the hearing-impaired person Before the presentation of a sound image, the hearing-impaired person, with the support of the acoustician, may choose from a plurality of sound images those that correspond to hearing situations to which the hearing-impaired person is frequently exposed and which are therefore typical of his everyday life.
  • the hearing-impaired person preferably does not select individual sound images but rather sound image groups, each of which contains a plurality of thematically related sound images.
  • sound image groups each of which contains a plurality of thematically related sound images.
  • these sound groups can be subdivided into thematic sub-groups.
  • the sound image group living area could be divided into the subgroups kitchen noises and television.
  • the representative of the selected sound pattern group is characterized in that its signal characteristics essentially correspond to statistical data of the signal characteristics of the sound patterns contained in the respective sound pattern group or subgroup.
  • the hearing impaired person is informed which sound image groups are available, whereupon the hearing impaired person specifies the sound image group relevant to him.
  • the selection process for the hearing impaired can be simplified in that, parallel to the acoustic presentation of a representative of a sound image group or subgroup, the hearing situation corresponding to the respective representative is presented visually.
  • the sound image groups it is also possible to offer the sound image groups to be selected only via the visual representation of their representatives and to dispense with an additional acoustic presentation of the corresponding listening situation.
  • the selection process described above can be computer-controlled, preferably using the same computing unit that is also used for the adaptation process according to the invention.
  • the acoustic presentation of representatives of the sound image groups during the selection process is preferably carried out via a loudspeaker system coupled to the computer, from which the corresponding sound signal reaches the hearing impaired person via the hearing aid.
  • the represented representatives can be displayed visually, for example, on any display unit coupled to the computer, in particular on a screen.
  • the selection decision made by the hearing impaired is entered into the computer either by the hearing impaired himself or by the acoustician using a suitable input medium, for example a keyboard or a touchscreen.
  • a further selection process is carried out, in which the subgroups relevant to the respective hearing impaired are also selected in the manner described will. If the selection process is computer-controlled, a corresponding branching in the program sequence takes place automatically when a sound group has subgroups, which triggers a further selection process in which the relevant subgroups are selected by the hearing impaired.
  • the hearing-impaired person can select several sound image groups or sub-groups, which are then taken into account sequentially during the subsequent adjustment process.
  • the hearing impaired person is presented with the selected sound image or the representative of the selected sound image group with the interposition of the hearing device.
  • This presentation is also computer-controlled and can be triggered, for example, by the hearing-impaired or by the acoustician by pressing a button.
  • This presentation also preferably takes place on a display device coupled to the computer.
  • the next step is an assessment of the hearing impression obtained by the hearing impaired.
  • several evaluation dimensions such as volume, timbre, degree of distortion, etc. can be taken into account.
  • the evaluation dimensions are divided into several levels, ranging for example from “too quiet” to “unbearably loud” in terms of volume, from “dark” to “glaring” in timbre and from “severely distorted” to “not distorted” in terms of the degree of distortion can.
  • Any finely graduated intermediate values can be provided between the aforementioned extreme values. In general, for example, the use of a 7-point scale can be appropriate. However, it is also possible to make a coarser or finer subdivision here.
  • the rating determined by the hearing impaired person is in turn entered into the computer by himself or by the acoustician using a suitable input medium, in particular using a keyboard or a touchscreen.
  • the input ratings can be displayed on a second evaluation screen, in particular a display type can be used in which the input rating is displayed in comparison to the rating given to the corresponding sound image or the corresponding representative of normal listeners.
  • a comparative representation can take place, for example, in the form of network diagrams which have an axis for each evaluation dimension, which is in each case scaled in accordance with the selected gradation of an evaluation dimension.
  • a network diagram is shown on each of these axes in each case the value determined by the normal hearing and the rating given by the hearing impaired. In this way, the acoustician is provided with clear, complex information about the hearing impression obtained by the hearing impaired.
  • the number of axes of the network diagrams or the number of assessment dimensions taken into account can be adapted to the hearing aid used in each case or to the individual requirements of the hearing impaired.
  • the hearing aid parameters are recalculated depending on the evaluation entered and the evaluation positions of normal hearing persons stored in the computer.
  • the hearing aid parameters used in the last presentation can also be taken into account in this calculation.
  • the newly calculated hearing aid parameters are displayed to the acoustician, for example on the screen, whereupon the acoustician has the possibility of individually adjusting the hearing aid parameters determined by the computer.
  • the acoustician has a suitable input medium for this.
  • the newly calculated hearing aid parameters or those determined by the acoustician are then transmitted to the hearing aid in a wired or wireless manner, where the corresponding adjustment is then carried out.
  • This hearing aid adjustment can also be computer controlled.
  • the hearing impaired person is then presented with the sound image or the representative again, the hearing aid parameters adjusted according to the above-described method now being used in this repeated presentation.
  • the described method can be used for different types of hearing aids, since it is independent of the type of the hearing aid through a suitable selection of the evaluation dimensions used and through the selection of those areas in which the hearing aid parameters can be adjusted.
  • Another advantage of the method is that the entire course of the selection and adaptation process can be stored in the computer. If necessary, a corresponding documentation can be displayed or printed out so that the course of the process can be traced at a later point in time.
