  • An automatic gain control AGC which responds to an input signal from a certain signal level can be provided.
  • the means for automatic gain control 4 are adjustable with regard to compression ratio and / or settling / decay time. For example, the settling / decay time can be influenced by changing the charging current of a capacitor that determines the time constant.
  • the filter means 5 of the analog part 1 form a filter stage consisting of high-pass filters 21, 22, which are provided for the simulation / generation of different microphone frequency responses. It is also possible to implement frequency responses that do not occur with conventional microphones.
  • the filter stage implemented in SC technology enables the use of a simple standard microphone 2 and can simulate or generate different microphone characteristics.
  • further filters 23, 24 are designed, which are provided for lowering or lowering and forming an NH or NL sound screen.
  • the filter means 5 of the analog part 1 further includes an anti-aliasing filter 25 at the entrance and a smoothing filter 26 at the exit.

  • additional setting means can be provided which the hearing care professional can use when adapting the hearing aid to the hearing damage of the hearing aid wearer enable the acoustician to further reduce the maximum gain specified by the manufacturer.
  • Such setting means can also be replaced by the software of a programming device that can be used to adapt the hearing aid.
  • An additional peak clipping block 29 limits the input signal symmetrically according to the programmed PC level and thus serves to limit the maximum output power.
  • a filter 30 (anti-heterodyne filter) is arranged in the signal path in front of the energy-saving class D output stage in order to avoid distortions of the class D output stage 7 and to limit the band of the input signal.
  • the analog part 1 is also designed so that its functional blocks are switched by switching means, e.g. Analog switches, are only activated as far as they are required for the special hearing aid type or for the special hearing damage or for a special selected operating mode, i.e. Function blocks of the analog part that are not required can be bridged and switched off by switching means. The ineffective function blocks do not require any energy and the hearing aid is operated in a battery-saving manner.
  • switching means e.g. Analog switches
  • the hearing aid is programmed via the serial interface 10, with programming data being able to be stored in one or more memories of the memory part 11 of the digital part 9. Based on this programming data, the digital part 9 acts as a control part on the analog part 1, it also providing adjustment values for the supply part 12.
  • the memory part 11 comprises at least one non-volatile memory (EEPROM), part of the memory being provided for the adjustment values or calibration values which Ensure compliance with the hearing aid data in accordance with the data sheet, a second part of the memory being provided for basic settings, which contain values for the permissible maximum gain setting (peak clipping) or the like, for example, and a third part of the memory for storing parameters or parameter sets for different hearing situations in adaptation to hearing damage is provided.
  • EEPROM non-volatile memory
  • the digital part 9 of the hearing device circuit 41 thus also contains a data memory 31, in which readable data relating to the manufacturer, the hearing device type, the circuit type used or the like can be stored. In order to protect certain programming data from undesired changes, special protection means / programming locks can be assigned to the data memory 31.
  • the MTO switch 40 is not arranged in the battery circuit as usual, but rather gives digital information about the desired hearing aid operation to the digital part 9, which then triggers the desired circuit.
  • a simple MTO switch 40 can be provided which also works less disruptively.
  • the cyclical selection of the program data from different stored listening situations is possible.
  • the hearing device circuit 41 finally comprises the supply part 12.
  • the supply part 12 supplies the programming voltage of approximately 15 V required for programming the memory part 11, which is generated from the battery voltage by means of so-called charge pumps (a cascade of voltage doublers 32). Furthermore, the supply part 12 supplies a supply voltage for the analog part 1 which is increased from the battery voltage by approximately 1.3 V.
  • the supply voltage for the analog part which is preferably doubled to approximately 2.6 V, is obtained from the battery voltage by means of a capacitive voltage doubler circuit.
  • the supply part 12 generates a very low-interference voltage of approximately 1.0 V for supplying the microphone 2. This low-interference voltage is obtained, for example, by means of a filter circuit.
  • the supply part 12 uses a clock generator 34 to generate clock signals for the analog part 1, such as for its class D power amplifier stage 7, for the filter means 5 and / or for a voltage doubler 32 or a voltage multiplier 33 of the supply part 12 . Furthermore, the supply part 12 has a unit 36 for the central supply of the analog part 1 with reference currents.
  • the hearing aid circuit 41 For simple and low-interference design of the hearing aid circuit 41, it remains connected to the battery 35 with the class-D power amplifier stage 7 of the analog part 1, with the digital part 9 and the supply part 12, even in the switched-off state, but a docoder 37 is provided in the supply part 12, which controls the operating state of the hearing aid circuit. So in the so-called stand by operating state, except for the decoder 37, all functional blocks of the hearing aid circuit can be switched off. Therefore, almost no energy is consumed in this standby mode. In the active operating state, the decoder 37 as a function of input signals 38, 39 the respective operating states are recognized and the functional blocks of the hearing aid circuit corresponding to these operating states are activated.
  • the input signals 38, 39 which characterize the operating states of the decoder 37 can be the switching signals of a switching means, for example the MTO switch 40 or a situation key 42 or the control signals of a remote control receiver of the hearing aid, if the hearing aid is a remote-controllable one.
  • a switching means for example the MTO switch 40 or a situation key 42 or the control signals of a remote control receiver of the hearing aid, if the hearing aid is a remote-controllable one.
  • the switches are not arranged in the battery circuit, can be made simpler and are less disruptive. Since the MTO switch 40 is not arranged in the battery circuit, interference injections to other parts of the hearing aid are reduced.
  • switching means for voltage monitoring of the battery 35 are preferably provided. For example, in the event of a voltage drop in the battery in the signal path to the receiver 8, changes in the amplification can be brought about, which serve as a request to change the battery.
  • the digital part 9 controls function blocks of the analog part 1, functional blocks which are not required for the selected operating state being switched off and bridged, so that only the current required for the active function blocks is taken from the battery 35.
