Definitions

  • the present invention relates to an acoustic system, in particular a hearing aid with a microphone device, a loudspeaker device, a signal processing device for receiving a first input signal from the microphone device and outputting an output signal to the loudspeaker device and a receiving device for receiving electromagnetic signals and outputting a second input signal to the signal processing device.
  • hearing aids can usually be manually switched to a corresponding hearing program. This switching occurs, for example, with the aid of a button.
  • the manual switching is uncomfortable and often takes place with a time delay, so that, for example, the beginning of a communication can not be perceived.
  • hearing aids have been developed that are able to automatically switch to a corresponding hearing program.
  • a hearing aid is from the document US 6,763,116 B2 known.
  • the recorded acoustic signal is examined for noise or noise components.
  • transmission parameters are changed or entire hearing programs are switched.
  • the EP 1 328 136 A2 discloses a hearing aid with a plurality of radio interfaces, which can receive signals corresponding to a plurality of signal sources via radio.
  • the signal sources are assigned addresses.
  • addresses are assigned priorities. The communication takes place in each case with the signal source of the highest priority.
  • the hearing device comprises a detector element for detecting electromagnetic interference signals.
  • a filter is provided which operates in response to the interference signals detected by the detector element so as to accurately suppress the detected interference signals.
  • the object of the present invention is thus to improve the automatic switching of acoustic systems or hearing aids on the basis of the received signals.
  • an acoustic system in particular hearing aid, with a microphone device, an output device, a signal processing device for receiving a first input signal from the microphone device and outputting an output signal to the output device corresponding to a hearing program from a predetermined number of hearing programs and one of microphone device and signal processing means present receiving means for receiving electromagnetic signals and for outputting a second input signal to the signal processing means, wherein the signal processing means comprises a high-frequency detector for analyzing the second input signal, with the output signal, the signal processing means is controllable so that a hearing program is selected from the predetermined number of hearing programs ,
  • the invention provides a method for selecting a hearing program of an acoustic system, in particular a hearing device, from a predetermined number of hearing programs, wherein in a hearing program, a first input signal is processed by a microphone device and processing of a second input signal from a receiving device for receiving electromagnetic signals, wherein the second input signal is analyzed for high-frequency components, and wherein the selection of the hearing program is performed in dependence on the analysis result.
  • processing is here also a switching off a signal and / or a connection of another signal, for. As a telecoil signal, understood.
  • a control signal is thus used for the signal processing which does not receive or process a corresponding acoustic system according to the prior art.
  • frequency components above 1 MHz are detected with the high-frequency detector.
  • This electromagnetic signals can be detected by mobile phones, so that, for example, a hearing aid can be switched to a corresponding phone program.
  • modulations of high-frequency signals can be detected with the high-frequency detector.
  • very specific signals can be detected, so that hearing aid programs can be switched very differentiated.
  • the receiving device may be designed to receive GSM, UMTS and / or Bluetooth signals.
  • the receiving device may also be equipped to receive signals from a cordless phone. The detection of these signals allows a very specific processing by automatic means.
  • the signal processing device can be switched into a respective processing program in dependence on the output signal of the high-frequency detector.
  • This automatic switching not only increases the comfort of the acoustic system but may also provide a larger number of switching programs that could not be selected by manual switches.
  • a particular advantage of an acoustic system or method according to the invention results from binaural care of a patient.
  • a level measuring device can be installed in the signal processing device of the two or both hearing aids to determine the level or the level difference of the output signals of the high-frequency detectors for further signal processing. In this way, it can be determined, for example, whether there is an electromagnetic near or far field. Accordingly, the signal processing can be switched.
  • FIG. 1 Hearing aid schematically illustrated by a circuit diagram has a microphone M, an audio input A and a telephone coil T.
  • a preamplifier V receives the signals of the audio input A, the microphone M and the telecoil T.
  • the preamplifier V has an A / D converter and a voltage regulator.
  • a digital signal processing D with clocked output stage receives the signal of the preamplifier V. Both, both the preamplifier V and the digital signal processing D are powered by a battery B with voltage. Furthermore, a VC-controller VC (volume control) for volume adjustment and a programming socket P for programming the hearing aid to the digital signal processing D is connected. Via an MTO switch MTO, the digital signal processing D can be switched to a microphone mode, a telephone mode or switched off.
  • an HF detector HFD is connected to the digital signal processing D. This analyzes the signals in the high-frequency range.
  • the RF detector may have its own receiving device or the signals of an otherwise usable receiving device, for. As a telecoil received.
  • the signal of the preamplifier V is processed according to the manually or automatically selected program or the parameters thus selected.
  • the resulting output signal is forwarded to a handset H.
  • electrodes, voice coils, vibration sensors, etc. may also be provided as output devices.
  • the high-frequency detector HFD evaluates in the hearing system, for example, a transmitted GSM signal at about 960 MHz or 1.8 GHz. This signal was sent in the immediate vicinity of the hearing aid by a mobile device and recorded by the antenna of the RF detector HFD. If the level of the GSM signal exceeds a predetermined threshold, this indicates that a GSM mobile device is being used by the hearing aid wearer. Accordingly, the hearing aid z. B. in a telephone program (Hörspulenprogramm) or a correspondingly adapted microphone program.
  • a transmitted GSM signal at about 960 MHz or 1.8 GHz. This signal was sent in the immediate vicinity of the hearing aid by a mobile device and recorded by the antenna of the RF detector HFD. If the level of the GSM signal exceeds a predetermined threshold, this indicates that a GSM mobile device is being used by the hearing aid wearer. Accordingly, the hearing aid z. B. in a telephone program (Hörspulenprogramm) or a correspondingly adapted microphone program
  • UMTS signals, Bluetooth signals or signals of a cordless telephone in the range of 2.4 GHz or 1.8 to 1.9 GHz can be received with the RF detector HFD.
  • specific modulations in the respective recorded signal can be searched for. For example, if UMTS-specific modulations are detected, it can be switched to telephone operation, since the hearing aid wearer is currently using a secure UMTS phone. Bluetooth transmitters transmitting in a frequency range close to the UMTS frequency band do not use the UMTS-specific modulations.
  • the sensitivity of the high-frequency detector HFD can be adjusted so that no program change takes place in the second hearing aid in the case of binaural supply.
  • the level of the radio frequency signal radiated from the mobile phone is on one hearing aid higher than the other. This level difference indicates that it is a telephone situation, so that the hearing aid can be switched to the telephone mode, which registers the high level.
  • the near field detected by the two hearing aids can thus be used for unambiguous switching of the hearing aid.
