Definitions

  • the present invention relates to a hearing device, in particular a hearing aid, with at least one operating element for adjusting an output sound level of the hearing device in that the operating element can be displaced into a plurality of setting positions. Moreover, the present invention relates to a method for monitoring the hearing of a minor hearing.
  • the hearing ability of a minor hearing is not constant, but a variable that can be changed through learning, aging and other processes. If a minor hearing-aid is already equipped with a hearing system, such a change should lead to a readjustment of the hearing system.
  • hearing system here refers to one or two hearing aids, which can optionally also be equipped with a remote control.
  • the remote control can also have functions that support the signal processing of the hearing aid / hearing aids.
  • a programmable hearing aid which has a controllable in its transmission characteristics amplifier and transmission part.
  • a microphone-downstream detector amplifier detects ambient or background noise, compares it with stored noise level patterns, and via a control circuit automatically activates one of the stored groups of parameters closest to the detected noise level pattern. The detector amplifier thus controls the transmission of the signals corresponding to the parameters after the actual hearing aid.
  • the document shows WO 03/098970 A1 a programmable hearing prosthesis with trainable automatic adaptation to acoustic environmental conditions.
  • the prosthesis includes a sound analysis module that monitors the acoustic environment of the user. The analysis module then provides an output representative of the type of auditory situation.
  • the prosthesis is also adjustable by means of a control.
  • the object of the present invention is to propose a hearing device with which the current hearing ability of the user during signal processing can be automatically taken into account.
  • a hearing device in particular a hearing device, having at least one operating element for setting an output sound level of the hearing device by the operating element being displaceable into a plurality of setting positions, a level measuring device for measuring an ambient sound level in the vicinity of the hearing device and an evaluation device for comparing a current one Setting position with a current, measured ambient sound level and for outputting a control signal in dependence on the comparison result.
  • a method for monitoring the hearing of a minor hearing by detecting a setting position of a control element, which serves to adjust an output sound level of a hearing device, measuring an ambient sound level in the vicinity of the hearing device, comparing a current setting position with a current, measured ambient sound level and output of a control signal as a function of the comparison result.
  • the hearing system or the hearing device thus advantageously recognizes a change in the hearing due to the settings chosen by the wearer and can either automatically make corrections or point out the fact to the minor hearing person. Thus, a change in the hearing and thus a shortage of the minor hearing does not go unnoticed. It should also be considered particularly advantageous that one or the other passage to the acoustician is spared.
  • a gain of the hearing device can be readjusted. This ensures that the user has the broadest possible setting range without having to permanently operate his device at a setting limit.
  • the hearing device according to the invention can have a signaling device in order to inform the user of the hearing device as a function of the control signal by an information signal.
  • a signaling device in order to inform the user of the hearing device as a function of the control signal by an information signal.
  • an acoustic or optical signal can be output to a hearing aid.
  • the hearing device may have a signal transmission device for transmitting the control signal or a corresponding signal to an external device.
  • the external device has a text output unit. In this way, the user can achieve a text message via a remote control, a smartphone and the like.
  • the hearing device may further comprise a memory device for recording a history of comparison results be provided, wherein the control signal is generated by the evaluation device in dependence on the history.
  • the time factor which characterizes the change in the hearing, can be taken into account in the information of the user or in the automatic readjustment.
  • one or more average values are continuously determined by the level measuring device. In this way, certain environmental situations can be better taken into account.
  • a specific embodiment of a hearing aid according to the invention is shown schematically in the figure.
  • the hearing device is equipped with a microphone M and a level meter P connected thereto, wherein the level meter P measures the level of the input signal or microphone signal 1. This detects the level of ambient sound.
  • the microphone signal 1 is also supplied in a conventional manner to a signal processing unit SE, which in turn generates an output signal for a loudspeaker L.
  • the level meter P generates a level signal 3 of the input signal 1 and supplies it to an analysis unit A1.
  • the analysis unit A1 also receives a position signal 2 of a control element, here a volume control LS.
  • the position signal 2 of the volume control LS is also used in the usual way in the signal processing unit SE.
  • the analysis unit A1 establishes a relationship between the position signal 2 of the volume adjuster LS and the level signal 3 of the level meter P and supplies a corresponding analysis value 4. This is supplied to a threshold detector SD and a persistent memory PS. Optionally, one or more analysis values 5, which were previously stored in the persistent storage PS, are provided by the persistent storage for the analysis unit A1, optionally including additional parameters. The output signal 4 of the analysis unit A1 is then calculated correspondingly including these analysis values 5 and optionally other parameters.
  • the threshold value detector SD receives, for example, a difference level, which the analysis unit A1 has determined from the ambient sound level 3 and a positioner level assigned to the positioner 2. If the difference level exceeds a predetermined threshold value, the threshold value detector SD triggers an activation signal 6 for a specific function. In the present example, a change of the parameter set of the signal processing unit SE is caused by the activation signal 6.
  • the hearing aid according to the invention can have a second analysis unit A2, to which the data 5 of the persistent memory PS are made available.
  • the second analysis unit A2 analyzes this data on the basis of certain predetermined criteria and performs one or more special functions, such. B. warning function or self-adjustment, off.
  • an analysis value 7 is supplied to the threshold value detector SD for this purpose.
  • the analysis unit A2 preferably also serves to analyze the data stored in the persistent memory PS in terms of time and, if appropriate, to provide corresponding mean values or other statistical data.
  • the level meter P will preferably be designed such that it can control the ambient sound level via a specifiable Averages the time interval and supplies the averaged value to the first analysis unit A1.
  • the level meter P is designed to continuously average over a short time interval, e.g. B. 30 s, and over a long time interval, for. B. 5 min, performs. In this case, as a result, two moving average values are available for the analysis unit A1 for improved analysis.
  • An alternative embodiment is to use two level meters, each having a frequency filter, z. B. a high-pass filter and a low-pass filter are connected upstream. Also in this case, two values are supplied to the first analysis unit A1.
  • the first analysis unit A1 is preferably designed such that it is activated for specific actuations of operating elements. It then stores in the non-volatile or persistent memory PS the data described above and optionally additionally a time and / or date stamp. Furthermore, the number of the selected hearing program and the current result of a classifier, which usually examines the incoming sound in the signal processing path of the hearing device and assigns it to one of several possible classes, can also be stored there.
  • the analysis unit A1 can be developed in such a way that it forms a difference value between the input signal level 3 and a setting level which has been assigned to the setting position of the operating element. This difference value is then stored in the memory PS. If the difference value exceeds a predetermined threshold value, then the gain controller of the signal processing unit SE is adjusted.
  • the analysis unit A1 first calculates the difference between input signal levels 3 and position 2, then calculates a moving average from this difference value and a number of last stored difference values and then activates a special function only when the moving average exceeds a threshold value.
  • a particular advantage of the type of signal processing according to the invention is that when processing the incoming audio signals and setting positions of operating elements, only the processing result is fed to a storage unit. This reduces the scope of the data to be stored, so that a hearing aid according to the invention can manage with a chip of smaller area. Thus, before the data storage, a comprehensive data preprocessing is performed. In this pre-processing, an analysis and feature extraction is performed so that the data volume of the result values is significantly reduced compared to the original input signals.
