  • Hearing aids are extremely complex systems. In order to meet the respective needs of consumers, it is necessary to provide a large number of different hardware configuration variants. This results in a highly cost-effective variety for both manufacturing and distribution and hearing aid fitting, e.g. In manufacturing a large number of different device configurations created, must be labeled and controlled accordingly, in sales a corresponding storage is required and in the device customization, each to the individual needs of the customer, depending on the existing device configuration, other approaches must be selected.

  • the hearing instrument identifies itself by determining via the comparison unit what its configuration is with respect to peripheral units.
  • Self-identification without the need for labeling, such as on the packaging avoids the possibility of error in production controls, in the distribution and adaptation of hearing aids, by excluding the possibility of testing an existing hearing aid on the basis of a supposedly different configuration of peripheral units. to deliver or adapt.
  • the output of the comparison unit is operatively connected to an operation selection input at the signal processing unit.
  • the operative connection between peripheral units and the central signal processing unit is established via a bus and via interface units.
  • the central digital signal processing unit is connected in hardware to the respectively provided peripheral units have to be.
  • the more options that are provided for the peripheral unit the more ports must be provided for the central signal processing unit. This number dominates more and more the necessary chip area for the mentioned signal processing unit, which is extremely disadvantageous especially in the miniaturization aimed at in the hearing device sector. Due to the fact that the mentioned active connection takes place via a bus and interfaces, a minimal number of provided hardware connections can be provided, which are utilized depending on the detected hardware configuration and the signals applied thereto are recognized and interpreted configuration-specific by the signal processing unit.
  • peripheral units can be used, inter alia, microphones, etc. generally sensors, speakers, etc., generally actuators, more transceivers, ie wireless transmitter and / or receiver, manual selector units, volume control (potentiometer), read-only memory, for example with Processing parameters for the signal processing unit, read / write memory eg for processing logging etc.

  • the actual configuration also determines which signals are transmitted to the central signal processing unit and thus which control parameters. If the identification of the peripheral units is automatically carried out on the hearing aid according to the invention, the possibility also exists of automatically activating from a plurality of possible signal processing configurations that corresponding to the prevailing configuration with peripheral units, or e.g. externally implement, e.g. via a transceiver, i. wireless. This eliminates the problem that signal processing processes are implemented on a hearing aid that do not correspond to the present configuration with peripheral units.
  • the hearing aid according to the invention has an output which is operatively connected to the configuration memory unit on the hearing aid. This creates the possibility, when the hearing device is connected to a computer-aided adaptation device, that the hearing device with its present configuration logs on to this device and identifies it so that errors in the adaptation due to incorrect assumptions with regard to the hearing device configuration are ruled out. Also this communication can be wireless, in that the mentioned output is formed by a transceiver.
