Definitions

  • the present invention relates to a method for adjustment a hearing aid by entering a desired setting value into the hearing aid at a determinable time. Furthermore, the present invention relates to a corresponding one Device for adjusting a hearing aid.
  • the setting of hearing aids is often through nowadays Adaptation formulas based on audiometric data achieved.
  • the audiometric data are, for example, the Hearing loss, the discomfort threshold, the volume scaling and the like are taken into account.
  • the fitting formulas are based on statistical and empirical knowledge and have therefore only conditional for the individual hearing aid user Validity. Especially for the optimal setting of the frequency and level dependent gain is therefore one time-consuming aftercare by a hearing care professional necessary. Another problem is that for the user optimal setting of his hearing aid only in realistic and found acoustic situations relevant to the user and can be verified.
  • the object of the present invention is therefore when setting a hearing aid more specifically to individual Conditions.
  • this object is achieved by a method for setting a hearing aid by entering a desired one Setting value in the hearing aid at a determinable time, Measuring at least one sound size a first environmental situation at the determinable time, automatic learning of setting values to be used in Dependence on the desired setting value and the minimum a measured sound size, re-measuring at least a sound size relating to a second environmental situation and setting the hearing aid to one of the ones to be used Setting values related to the second environmental situation.
  • a device for setting a hearing aid with an input device for entering a desired setting value into the hearing aid at a determinable time, a measuring device for measuring at least one sound size related to a first environmental situation at the determinable time and of at least one sound variable relating to a second environmental situation, and a computing device for automatic Learning of setting values to be used depending on the desired setting value and the at least one measured value Sound size regarding the first surrounding situation, one of the setting values to be used by the computing device can be output in relation to the second surrounding situation is.
  • the entry is preferably made using a separate key on Hearing aid, the volume control, the remote control and / or a voice input device. It is sufficient to have an impulse to Save to hand over to the hearing aid. For example selected gain together at the push of a button be saved with an acoustic surrounding situation.
  • the at least one measured sound size can be the minimum or maximum sound pressure level in a frequency channel or the modulation depth. Based on the in individual situations Measured variables obtained can be the gain or Compression can be readjusted as a setting value.
  • the learning is preferably carried out by weighting the learning steps over time. It can be determined whether and how quickly the " self-adjustment" should converge.
  • the learning steps can be at predetermined times and / or be carried out in a predetermined number. On too a learning step can be carried out for individual requirements. This allows learning at the desired speed and precision.
  • An adjustment device is preferred directly integrated into a hearing aid, so that the setting or adapting the hearing aid without a device Effort can be made. For reasons of space, it can be especially at so-called in-the-ear hearing aids may be necessary for Adjust an external adjustment system to use in the the adjustment device described above is integrated. The setting values of the Setting system to be transmitted to the hearing aid.
  • the user first sets the gain according to block 1 Hearing aid manually when it is in a certain acoustic Situation. If this acoustic situation is characteristic for him, he solves one according to block 2 Adjustment process of his hearing aid. This is done either manually or timed at certain intervals or otherwise automatically. Is the adjustment process triggered, the current environmental situation becomes audible measured, as shown in block 3.
  • the measured values obtained and the manually selected gain value are used to create a new characteristic field determined according to block 4. There is a in this characteristic field Variety of environmental situations with appropriate reinforcements connected.
  • the hearing aid calculates the characteristic field (block 4) automatically a new one that fits this new environment Reinforcement, as indicated in block 6.
  • the setting value of the hearing aid is not just that the gain selected in the example, but if necessary also compression and the like.
  • the hearing aid is automatically set for example, that the user in the hearing aid acoustic situations relevant to him via the volume control, the remote control, a voice input etc., the desired one Reinforcement announces.
  • the desired one Reinforcement announces.
  • the required data are stored in the hearing aid or stored externally and the evaluation in the hearing aid or externally for example using a PC or remote control.
  • the evaluation can be done after a certain time, a certain Number of control activities or at the request of the user for determining level and frequency-dependent gains respectively.
  • determining the hiring can be determined by a temporal weighting whether and how quickly self-adjustment should converge.
  • the hearing aid wearer also has the option of to influence this temporal weighting by a corresponding one Perform fine adjustment.
  • the advantageous use of the self-adjustment according to the invention can be shown in the following example.
  • the gain from Users reduced while at medium and low levels no changes are saved.
  • the hearing aid changed the characteristic field then so that the compression ratio is increased in the low-frequency channels.
