Definitions

  • the present invention relates to a method for adjusting a hearing device by automatically analyzing a hearing situation in which the hearing device is located, and an automatic setting of a parameter of the signal processing device of the hearing device as a function of the hearing situation in a first parameter range. Moreover, the present invention relates to a corresponding hearing device with such analysis and adjustment options.
  • hearing device is understood in particular to mean a hearing device.
  • the definition also includes any other portable and non-portable communication systems in which hearing plays an essential role, such as headsets and headphones.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE), in-the-ear hearing aids (IDO) and Concha hearing aids are provided.
  • BTE behind-the-ear hearing aids
  • IDO in-the-ear hearing aids
  • Concha hearing aids are provided.
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. B. miniature speakers, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit.
  • FIG. 1 shown using the example of a behind-the-ear hearing aid.
  • a hearing aid housing 1 for carrying behind the ear one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • a noise reduction algorithm for example, a noise reduction algorithm, a directional microphone or a feedback compensator (in the subcritical case) should not be activated when the hearing aid wearer is sitting in a concert.
  • a noise reduction algorithm would attack the payload and produce artifacts.
  • a directional microphone would give the spatial sound impression undesirable change.
  • a feedback compensator would produce unwanted artifacts.
  • the hearing aid system comprises an adaptation device which essentially has a first memory for a plurality of parameter sets available for each of a plurality of listening situations and an input device for selecting a currently present audible situation and one of the several parameter sets available for selection for this auditory situation.
  • the hearing aid system has a second memory for assignment data relating to the sets of parameters selected for each listening situation.
  • it is essentially proposed to assign a user-specific optimal parameter set to each optimally occurring hearing situation and to select the determined assignment data for determining an optimal parameter set for each hearing situation after the optimization phase.
  • a hearing aid with a control device known.
  • the acoustic listening environment in which the hearing aid is located is analyzed and, depending on the hearing situation detected thereby, at least one control element is assigned a setting function dependent on the respective hearing situation.
  • the adjustment of the hearing aid is thereby limited to the reasonable for the particular hearing situation settings.
  • EP 1 432 282 A2 a method for adapting a hearing device to a current acoustic environment situation and a corresponding hearing aid system is known.
  • the hearing device is used to set a parameter set belonging to the ambient situation and stored in the hearing device. Parameters of the set parameter set can be adjusted by means of an input part which can be actuated by the hearing aid wearer in accordance with the listener request of the hearing aid wearer.
  • the object of the present invention is to take better account of the subjective feeling when adjusting the hearing device.
  • a method for setting a hearing device by automatically analyzing a hearing situation in which the hearing device is located and automatically setting a parameter of the signal processing device of the hearing device as a function of the hearing situation in a first parameter range and manually setting the parameter of the signal processing device to a value in a second parameter range outside the first parameter range, wherein the automatic setting in the first parameter range is terminated thereby, wherein an acceptance or a perception threshold for an artifact is specified in the signal processing, for the automatic adjustment of the first parameter range is set such that the Artefact is below the Acceptance or Perceptibility Threshold, and when manually adjusting in the second parameter area, the artifact is above Acceptance or Perceptual mbars threshold lies.
  • the invention provides a hearing device with a signal processing device, an analysis device for automatically analyzing a hearing situation in which the hearing device is located, and an adjusting device for automatically setting a parameter of the signal processing device as a function of the analyzed auditory situation in a first parameter range in which Artifact of the signal processing of the signal processing device is below a predetermined acceptance or perception threshold, wherein the setting means for manually setting the parameter of the signal processing means is designed to a value in a second parameter range outside the first parameter range, and the artifact in the second parameter range above the acceptance or Perceptibility threshold is.
  • the invention provides a hearing device with a signal processing device, an analysis device for automatically analyzing a hearing situation in which the hearing device is located, and an adjusting device for automatically setting a parameter of the signal processing device as a function of the analyzed auditory situation in a first parameter range, wherein the setting device for manually setting the parameter of the signal processing device to a value in a second parameter range outside the first parameter range.
  • control of the hearing device or communication system thus takes place semi-automatically.
  • the effectiveness of the performance characteristics of the hearing device can thus be adjusted individually at any time, whereby the subjective impressions are better taken into account.
  • the full range of effects of the algorithms can be exploited, which otherwise is not possible due to the necessary compromise setting of the parameters.
  • artifacts may be accepted by manual adjustment, but the particular algorithm is operated with increased strength compared to the automatic adjustment range.
  • the value in the second parameter range is also changeable. This can be done, for example, manually and possibly continuously. Alternatively, an automatic adjustment can also take place in the second parameter range. Thus, automatic functions can also be used in a "forbidden" area.
  • the value in the second parameter range can be permanently stored in the hearing device. It is particularly advantageous if this value is stored as a variable software value, for example in the basic setting or adaptation, in the hearing device. In this way, for example, a hearing aid can be customized.
  • the value in the second parameter range can also be changed automatically depending on a current hearing situation.
  • an automatic value adjustment can also take place as a function of a classifier decision.
  • the parameter itself which is to be set, may also be selected automatically depending on a current hearing situation. In this way, the possibilities for semi-automatic adjustment can be significantly increased.
  • the signal of a signal input SE is fed to a signal processor SV.
  • the output signal of the signal processing device SV is provided at a signal output SA.
  • an analysis / logic unit AL which also picks up the signal from the signal input SE.
  • the analysis / logic unit AL provides two output signals: Alternative 1 and Alternative 2. Both alternatives represent parameters for the control of the signal processing device SV.
  • the hearing aid wearer or the user of the communication system selects the parameter suitable for him or the respective alternative.
  • the parameter according to alternative 1 is automatically selected as a function of the respective listening situation. This means that the communication system operates without a user request with a middle or a classifier-controlled setting. If the user is not satisfied with this setting, he can increase the effectiveness of the underlying algorithm by pressing the manual switch S.
  • Switching to the alternate mode can also be accomplished by actuating a button, thereby switching the system to a select mode.
  • actuating a button thereby switching the system to a select mode.
  • the desired setting is acknowledged by pressing the button again.
  • the mode of operation of the method according to the invention or of the hearing device according to the invention will now be described with reference to FIG. 3 explained in more detail.
  • a noise reduction algorithm be set semi-automatically.
  • the level of the noise decreases.
  • this also increases the level of artifacts that result when the parameter value is increased.
  • the threshold of perceivability is also shown below which the sounds or artifacts are not audible.
  • the automatic signal processing is set to select the parameter value from a classical setting range PB1. In this area, the artifacts of the noise canceling algorithm are imperceptible (or acceptable if it is the acceptance threshold).
  • the noise remaining after the noise algorithm can be further reduced by further increasing the parameter value of the noise algorithm.
  • the artifacts are then perceptible and can be expressed, for example, in a bubbling noise, which results from modulating to a useful signal.
  • the user now decides whether the artifacts are acceptable to him and therefore manually selects the parameter range PB2 or a value thereof. He then accepts the artifacts and benefits from a lower noise level.
  • the inventive principle can also be used, for example, for speech intelligibility.
  • the directional characteristic of a hearing aid can be increased with one parameter. However, this is accompanied by the fact that more and more are lost in the output signal. In an automatic setting range, the directional characteristic is therefore only automatically adjustable to a certain extent. The user can now accept in favor of a better directivity that depths are increasingly lost. In this case, he would manually select the additional adjustment range PB2.
  • the semiautomatic control according to the invention thus takes place according to the principle that the system offers at least two setting alternatives to one or more performance features of the communication system or the hearing device, from which the user actively selects the best for him.
  • the device offers two setting alternatives: a "defensive” setting and an "aggressive” setting. The user presses a switch / button and thus acknowledges the preferred alternative for the respective hearing situation.
  • the alternative parameter settings can either be permanently stored in the system or determined at any time by an analysis unit in combination with a logic adapted to the situation.
  • the selection of the features that are suitable for this concept and the selection of the parameters of these features can be fixed or user-programmable.
