Definitions

  • the invention relates to a hearing aid with operating time-controlled adaptation of the transmission characteristic. What is to be understood by this follows from the following description.
  • the invention has for its object to provide a better solution to the problem shown. This object is achieved according to the invention by the hearing aid specified in claim 1 with operating time-controlled adaptation of the transmission characteristic.
  • Advantageous embodiments of the invention are the subject of the dependent claims.
  • the invention is based on the fact that digitally programmable and fully digital hearing aids have been available on the market for some years.
  • the current state of the art in this regard is that one or more transmission characteristics, e.g. can be permanently programmed into the hearing aids for different noise situations.
  • the hearing aids then automatically regulate the gain depending on the existing input level. Volume controls are no longer necessary in modern hearing aids.
  • the invention makes use of the technical possibilities now given for overcoming the problem described above.
  • This includes equipping the hearing aid with an integrated time function, that is to say with a kind of operating hours counter. After an audiological frequency and dynamic adjustment has taken place, a volume that the patient perceives as pleasant is stored as a starting point in the hearing aid. The curve that is audiologically desirable from an objective point of view is entered as the target transmission curve. Finally, it is stored in the hearing aid in what time period, measured in operating hours of the hearing aid, and in which steps the target curve is to be reached. The hearing aid now automatically adjusts the hearing aid in the smallest possible steps or gradually in the direction of the audiological target curve. This programming can be changed not only in terms of volume, but also in terms of dynamics and frequency parameters via the time parameter in the direction of the target curve.
  • the time-controlled adaptation of the following parameters can be programmed. a) the overall volume at the output;
  • the dynamics i.e. the gain depending on the respective input level, i.e. higher gain at low input levels and lower gain at higher input levels, or compression, i.e. the ratio of input signal to output signal,
  • a hearing aid according to the invention is shown in a schematic form as a block diagram. This is referred to in the following.
  • the hearing aid has a microphone 1 as an input element and a loudspeaker 2 as an output element and in between an amplifier arrangement 3.
  • the transmission link between the microphone 1 and the loudspeaker 2 is preferably constructed in multiple channels in order to enable a differentiated transmission characteristic in the individual frequency ranges of the overall frequency range.
  • the fully digitized or analog, but digitally programmable hearing aid also has a time counter 4.
  • the clock is generated in the usual way and is not shown here for simplicity.
  • a processor 5 which is correspondingly programmable, contains, in stored table form, a target curve of the desired transmission characteristic of the hearing aid and an initial transmission curve of the transmission characteristic when the Use of the hearing aid and data on the time-dependent change in the transmission curve in the direction of the target transmission curve.
  • a specific frequency range can be assigned to each individual channel of the amplifier arrangement 3.
  • Each channel contains an amplifier 3a, 3b ..., a gain control element 6a, 6b ... and possibly an adjustment element 7a, 7b ... for influencing the transmission characteristics in the respective frequency range.
  • An actuator 8 in the overall channel is used to set parameters such as overall volume or the like.
  • the processor controls each of the one-part elements 6a, 6b ..., 7a, 7b ..., and 8 in accordance with the overall transmission characteristic to be generated. According to the overall transmission characteristic to be generated.
  • the processor 5 gradually changes the transmission characteristics of the hearing aid in gentle stages or quasi-continuously from the initial transmission curve to the target transmission curve by selectively adjusting the setting elements 6, 7 in the individual transmission channels of the amplifier arrangement 3, in accordance with the time counting in the timer 4 , after which the setting remains fixed.
  • the user thus experiences an adaptation of the transmission characteristic that is not noticeable to him and not perceived as uncomfortable to his hearing ability which increases over time as habituation increases again with normal hearing conditions.
