Definitions

  • the present invention relates to a method for operating a hearing device and a hearing aid according to the preamble of patent claim 5.
  • Modern hearing aids can be adapted today with the help of different hearing programs to different acoustic and / or inductive environmental situations. Thus, the hearing aid should bring the user an optimal benefit in every situation.
  • the adaptation i. The switching between different hearing programs, takes place manually by pressing a switch or a remote control and automatically with the aid of a suitable algorithm.
  • a method for the automatic detection of the current acoustic or inductive environment situation and for setting a hearing aid program which is most suitable in the determined acoustic environment situation is known from the published patent application of the international patent application with the publication number WO 01/22 790 A2 or US Pat. No. 6,895,098.
  • the known teaching is a very efficient algorithm with the aid of which the acoustic environment situation can be determined with high reliability.
  • EP-0 674 464 A1 a method for automatically switching between hearing programs by means a fuzzy logic controller known, which is realized in analog technology.
  • EP-0 064 042 A1 discloses a programmable signal processing unit which enables manual and automatic switching between hearing programs. However, usable criteria for the switching operation are not mentioned.
  • the object of the present invention is to further improve a method for operating hearing aids.
  • the invention is characterized in particular by the following advantages: By recording a signal with at least one of a plurality of source units by classifying at least one of the recorded signals into one or more predetermined noise classes, wherein characteristics of the source unit which records the signal in the Classification can be considered, and by selecting a hearing program based on the classification, the classification can be made faster and more accurately. This makes it possible to select the hearing program that is most suitable for a current acoustic environment situation more quickly. Thus, a method for operating a hearing aid has been provided that allows for faster adaptation a hearing aid to actually prevailing operating conditions allows.
  • the single figure in a schematic representation, shows a block diagram of a hearing aid according to the present invention.
  • hearing aid means both so-called hearing aids, which are used to correct a damaged hearing of a person, as well as all other acoustic communication systems, such as radios to understand. Furthermore, all forms of application, such as implantable hearing aids, under the term “hearing aid” to understand.
  • the hearing aid consists of a selection unit 2, a signal processing unit 1, a classification unit 3, a digital-to-analog converter 4 and a receiver 5, which is designed, for example, as a miniature loudspeaker.
  • the source units S1 to Sn are operatively connected to the signal processing unit 1 via the selection unit 2, wherein the signals received by the source units S1 to Sn are converted into digital signals in the selection unit unless the received signals are already in digital form.
  • the block diagram shown in the figure represents a digital hearing aid, it is conceivable that the invention may also be applied to a hearing aid that is wholly or partially realized with analog components. In such an analog embodiment of the invention, the analog-digital and digital-analog converters are not absolutely necessary.
  • the output signal of the selection unit 2 fed to the signal processing unit 1 is additionally subjected to the classification unit 2 in which a momentary acoustic ambient situation is determined on the basis of characteristic features.
  • the classification unit 2 in which a momentary acoustic ambient situation is determined on the basis of characteristic features.
  • the classification unit 2 during an extraction phase extracts the characteristic features that serve as the basis for the classification of the current acoustic environment situation.
  • the result of this classification is thus the identification of the current acoustic environment situation or the indication of the most probable momentary acoustic environment situation.
  • information is also processed in the classification unit 3 in connection with the selected or selected source units S1 to Sn.
  • a hearing program can be selected which is best suited for processing the signals recorded with the source units 51 to Sn, at best taking into account the sound image desired by the hearing aid wearer.
  • the block diagram according to the single FIGURE shows the selection of the hearing program by the classification unit 3 by the active connection between the classification unit 3 and the signal processing unit 1 designated by PS according to the invention.
  • the selection unit 2 in addition to a possible analog-to-digital conversion of the signals received from the source units S1 to Sn, one or more active source units S1 to Sn are selected.
  • the selection can either manually, for example by the hearing aid wearer, or automatically, for example by the signal processing unit 1.
  • the manual selection is indicated by the active connection designated M in the figure, via which, for example, a switch on the hearing aid itself or a remote control (both not shown in the figure) informs the hearing device or the selection unit 2 which Source unit or source units S1 to Sn serve as a signal generator.
  • the hearing aid can be informed about the same input options, for example, whether the selection of the active source unit or source units should be automatic or not.
  • the automatic selection of the source unit S1 to Sn is carried out by the signal processing unit 1, which is connected to the selection unit 2 via the connection A for this purpose.
  • Another possible method is that the source unit S1 to Sn is selected, which generates a signal in the time and / or in the frequency range, which comparatively has the highest level.
  • At least one hearing program is provided for each source unit S1 to Sn, which is particularly suitable for the respective source unit S1 to Sn.
  • the corresponding hearing program is executed in the signal processing unit 1. This takes into account the fact that certain source units S1 to Sn inherently imply a certain acoustic ambient situation and under certain circumstances themselves influence the sound image, for example in dynamics and / or frequency response. This acoustic ambient situation inherently contained in the source unit S1 to Sn is taken into account in the corresponding hearing program.
  • the hereby implied acoustic environmental situation is the following:
  • the signal is inductively applied to the hearing aid given; the room acoustics is therefore insignificant.
  • the useful signal is typically taken directly from a source (eg a speaking voice through a microphone) or fed (eg tape recordings, recorded announcements).
  • the inductive useful signal can be superimposed by inductive interference fields.
  • interference fields are, for example, hum sources of transformers, coils, power cables or fluorescent tubes.
  • Possible remedies for the reduction of the interference fields are, for example, the use of interference suppression filters, which lower the signal level in the frequency range of the hum sources. In the acoustic signal path of the hearing aid, the room acoustics can not be improved.
  • a telecoil affects the sound pattern so that the sensitivity is lower at high and low frequencies. In the middle frequency range, however, the sound is the same as a hearing aid microphone. Therefore, to reduce the soundscape changed by a telecoil, the high and low frequency ranges are reproduced more.
  • a useful signal is transmitted to the hearing aid via an FM transmission path, so the acoustic environment situation directly in the hearing device is insignificant.
  • a useful signal transmitted via the FM transmission path typically becomes direct added. For example, with a remote microphone, a speaking voice is recorded directly at the speaker, or a tape recording or a recorded announcement is input.
  • NF low frequency
  • the transmission over an FM transmission link typically has less dynamics, a likewise limited frequency response and higher noise.
  • the assumed acoustic environmental situation is similar to that of a telecoil. Eventually, a signal already transmitted via an FM transmission link is fed into the hearing aid via the audio input. Accordingly, they apply the above-mentioned measures to improve the useful signal.
  • the signal injected through an audio input is typically extremely broadband (e.g., from a CD player) and has high dynamics. Accordingly, the broadband signal is to be further processed with a suitable dynamic behavior of the hearing aid amplifier.
  • Source multiple sources, e.g. FM transmission link and microphone or microphone and telecoil
  • a further embodiment of the present invention is that when switching from one source unit S1 to Sn to another and thus a hearing program change from a first to a second hearing program is made such that a generated due to the first hearing program output steadily into a by the second hearing program generated output signal passes.
  • the hearing aid wearer is not surprised or unsettled by a hard switch from one hearing program to a second. Rather, then the Hörprogrammumscnies for the hearing aid wearer is only noticeable by the fact that the hearing is gradually improved by choosing a better hearing program.
