Definitions

  • the invention relates to a programmable hearing aid with an amplifier and transmission part that can be adjusted in terms of its transmission properties between the microphone and the listener to different transmission characteristics.
  • EP 0 064 042 B1 discloses a circuit arrangement for a hearing aid in which, for example, the parameters for eight different environmental situations are stored in the hearing aid itself in a memory.
  • a switch By actuating a switch, a first group of parameters is called up and controls, via a control unit, a signal processor connected between the microphone and the receiver, which then sets a first transmission function intended for an intended environment. All eight transfer functions can be called up in succession via a switch until the right one is found.
  • there is also an automatic switchover between permanently programmed transmission functions if the user e.g. comes from a noisy environment to a quiet environment or vice versa. This switchover also takes place cyclically. If you want to set other than the stored transfer functions, the non-volatile memory must be deleted by an external programming unit and re-programmed by this.

  • An adjustment to Constantly changing environmental situations are neither intended nor possible, not even by remote control.
