  • the hearing aid care of people with multiple disabilities or the care of children is essentially based on the fact that the caregivers are involved in the fitting process and also in the subsequent aftercare process.
  • these persons play an essential role in the daily environment of the hearing aid wearer and may also fit parameters of a hearing aid, such as a hearing aid.
  • a hearing aid As the volume of the hearing aid for the hard of hearing. They are only dependent on experience. However, they do not know which problem the deaf person actually has. Thus their interventions in the hearing aid setting are not necessarily correct.
  • the object of the present invention is thus to facilitate the adjustment or adaptation of a hearing device for a user or for a user caring for the user.
  • a hearing device having a signal processing device for processing an input sound to an output sound, a perceptive model being implemented in the signal processing device or in a processing device in data communication with it, with which a psychoacoustic variable can be provided in relation to the output sound, wherein a visualization device is connected to the signal processing device or the processing unit to visualize a value of the psychoacoustic quantity.

  • the signal processing device supplies the psychoacoustic variable in the hearing aid, it is not necessary to transmit a broadband signal to an external device for visualization, which first calculates a psychoacoustic variable from it using a perceptual model.
  • the hearing device comprises a remote control which contains the visualization unit and the processing device. Since hearing aids are operated in many cases with a remote control, thus no additional device for the visualization is necessary, which facilitates the handling of the hearing aid.
  • the hearing device and the remote control each have a communication device with which the respective current value of the psychoacoustic variable provided by the signal processing device can be transmitted from the hearing device to the remote control for optical representation.
  • a plurality of psychoacoustic variables can be provided by the signal processing device or the processing device and the corresponding values can be visualized by the visualization device. If necessary, several values can be visualized simultaneously. For example, sound quality and speech intelligibility can be visualized at the same time that the user or the caregiver can find a compromise of these sizes if they have an opposite effect.
  • the hearing device may comprise an analysis device in order to analyze a current auditory situation, so that at least one psychoacoustic reference value can be generated independently of a setting of the signal processing device from corresponding analysis values with the perceptive model of the signal processing device or processing device, which is generated by the visualization device together with a psychoacoustic value regarding an actual setting of the signal processing device is optically displayed.
  • the current psychoacoustic value it is also possible to visually represent, for example, a maximum value and a minimum value, possibly also an average value resulting from the current auditory situation, whereby the person performing the setting obtains objective clues for the attitude.
