Definitions

  • the present invention relates to a hearing system with at least two hearing devices, which are designed for wireless communication with one another, and a transmission station, by means of which messages can be transmitted between the hearing devices.
  • Hearing devices are understood to mean not only hearing aids but also headsets, headphones and the like.
  • the analog transmission of the audio signals is typically carried out with the aid of a modulated carrier.
  • the hearing aids have corresponding AM / FM receivers.
  • the behind-the-ear hearing aids also have AM / FM transmitters.
  • the document describes DE 602 02 618 T2 a cellular system for asymmetric wireless communication with a carrier wave for the downlink and ultra-broadband for the uplink.
  • a mobile communication device has a carrier wave-based receiver and an ultra-wideband transmitter. Since less power is required for an ultra-wideband broadcast than for a carrier wave broadcast, the mobile communication device benefits from this power saving.
  • the communication from the base station communication device to the mobile communication device is by a carrier wave transmission.
  • the document discloses US 2005/0283207 A1 a transmission between an external hearing aid and a low power implant.
  • the hearing device and the implant each have a transmitting and receiving unit with a coil for inductive transmission.
  • ultra-wideband pulses of very short duration are used.
  • the object of the present invention is to propose a hearing device with which wireless communication with low energy consumption and increased data transmission rate is possible.
  • a corresponding hearing system is to be specified, in which several hearing devices communicate in the manner mentioned.
  • this object is achieved by a hearing system according to claim 1.
  • digitally modulated magnetic field signals can be transmitted between the hearing devices.
  • digitally modulated magnetic field signals can be transmitted between the hearing devices.
  • For a secure transmission with low hardware cost is possible.
  • the bandwidth of each of the broadband pulse transmitters is at least 100 MHz. As a result, a relatively high data rate can be realized.
  • Each of the broadband pulse transmitters is connected to a miniaturized electrical antenna. Their maximum extension is preferably between 8 and 20 mm. Thus, the size of the hearing devices and in particular the hearing aids can be reduced.
  • bidirectional, quasi-simultaneous communication can be carried out between the hearing devices via the transmission station.
  • This quasi-simultaneous bi-directional communication is possible in that the communication in a time window in one direction and in a subsequent time window in the other direction. This allows the transceivers to be realized with little effort.
  • the transmitting station may have a bidirectional interface to an external configuration device.
  • configuration data can be transmitted from the configuration device via the transmission station to one of the hearing devices.
  • the transmitting station receives the dual functionality of transmitting signals between the hearing devices, but also signals from a configuration device to a hearing device.
  • the FIG shows a hearing aid wearer who carries a left hearing aid HG-L in his left ear and a right hearing aid HG-R in his right ear.
  • the communication between both hearing aids via a portable base unit BG.
  • This base unit BG can wear the hearing aid wearer, for example, in his breast pocket and it takes over the function of the transmission station.
  • HG-R and HG-L digital receiver and transmitter for audio signals are separated. Both are adapted to the extreme requirements of hearing aids in terms of size and power requirements. If the remote station of the communication is a portable base unit BG with less critical requirements, then more complexity can be used for the transmitters and receivers incorporated therein, with the aim of compensating for the limitations in the hearing aids.
  • a miniaturized coil is used in a favorable embodiment.
  • Their maximum extension is preferably between 4 and 8 mm.
  • Such coils are used, for example, for remote controls of hearing aids.
  • the receiver coils of the hearing aids receive the digitally modulated magnetic field signal of a transmitter, which has a much larger and thus more effective transmission coil and is installed in the base unit BG.
  • the signal course is symbolized in the FIG by arrows from the base unit BG to the hearing aids HG-R and HG-L.
  • the inductive transmitter is in the FIG with TX designated. It is driven by a signal processing unit P, which has a memory, and a communication interface C.
  • the base unit BG a battery B, and not shown operating and display elements.
  • a likewise miniaturized electrical antenna is used, which emits broadband pulsed signals with low transmission field strength.
  • the technique of transmitting broadband pulsed signals is known from the aforementioned article "An Ultra-Wideband Transceiver Architecture for Low Power, Low Rate, Wireless Systems". With this technology, signals can be emitted by the transmitter with very low power consumption. These signals are shown with arrows from the hearing aids HG-R and HG-L to the base unit BG in the FIG.
  • the weak, broadband pulsed signals in the base unit BG can be received with sufficient quality, there is a much larger and thus more effective electrical receiving antenna installed.
  • the receiving circuit or the receiver RX is also realized very expensive to reliably detect the weak signals.
  • the digital audio signal can be passed through the base unit BG from one hearing aid HG-R to the opposite hearing aid HG-L or vice versa.
  • the digital audio signals can be passed through the base unit BG from right to left and quasi-simultaneous from left to right.
  • control signals are transmitted from the base unit BG, which effect an alternating transmission of the broadband pulsed signals of the hearing aids HG-R and HG-L involved.
  • a bidirectional interface to a configuration unit KG is optionally provided.
  • the interface may be either a simple serial wire interface (eg Universal Serial Bus) or a wireless interface (eg Bluetooth, Zigbee, WLAN).
  • the bidirectional interface can also be used in a further step to reconfigure programmable hearing aids.
  • programming data is transmitted instead of the digitized audio data, and the base unit operates as a transmitting station from and to the configuration device.
  • the configuration device may be a PC or notebook on which the fitting software for the hearing care professional is installed.
  • the rapid data rate of the hearing aids is a great advantage, as it allows the complete reading out of the data stored in the hearing aid very quickly.
