Definitions

  • the present invention relates to a hearing aid device for automatically switching to a telephone operation with a first hearing aid including a first receiving device for receiving a first input signal and a second hearing aid including a second receiving device for receiving a second input signal.
  • a hearing aid device for automatically switching to a telephone operation with a first hearing aid including a first receiving device for receiving a first input signal and a second hearing aid including a second receiving device for receiving a second input signal.
  • the present invention relates to a corresponding Method for automatically switching to a telephone operation.
  • Modern hearing aids are usually capable of different Listening situations by doing that they from the hearing aid wearer in different hearing programs can be switched.
  • a typical hearing program is that Telephone listening program, in which sounds the microphone of the hearing aid, according to the frequency spectrum be filtered by phone signals to annoying ambient noise in other spectral ranges.
  • the document EP 1 298 959 A2 likewise discloses a method known, with which the Hörspulensignal for the automatic Switching into the hearing coil or telephone operation analyzed becomes.
  • This interfering signals z. B. by cordless phones or mobile phones according to the DECT or GSM transmission standard can emerge as a basis for a Switching signal used.
  • DE 101 46 886 A1 is likewise a method is described with which to be recognized automatically should when the hearing aid wearer is on the phone. In this process the signal from the listening coil and the signal is off compared to the hearing aid microphone and a corresponding Switching signal generated.
  • the object of the present invention is therefore to to provide an apparatus and a method with which a situation in which the hearing aid wearer is on the phone, with higher security can be detected.
  • a hearing aid device for automatic switching to telephone operation with a first hearing aid including a first Recording device for receiving a first input signal and a second hearing aid with a second receiving device for receiving a second input signal and a Level measuring device for measuring a level difference of both Input signals and a control device for switching at least one of the two hearing aids in the telephone operation, if the level difference is at least one predetermined Threshold below or above.
  • the invention provides a method for automatic Switch to a telephone operation by winning a first input signal in a first hearing aid and winning a second input signal in a second hearing aid and measuring a level difference of both input signals and turn on at least one of the two hearing aids the telephone operation, if the level difference at least one specified threshold falls below or exceeds.
  • the first and second receiving means comprise one auditory coil each.
  • the hearing coils of both hearing aids can be significantly higher level differences when making a call notice than with microphones, since the Konieren usually does not take place in soundproof rooms.
  • the level gauge may include two level meters for measuring the absolute level of the first and second input signals include.
  • the control unit can then by a subtractor or divider, but also by bit arithmetic the level difference Both input signals are formed. This has the advantage that, if necessary for a "smart" evaluation the input signals both the absolute and the Differential level is available.
  • At least one of the two input signals can be inductive transmitted signal of an analog telephone. Thereby forms the inductively transmitted voice signal of the analogue telephone the basis for determining the level difference and consequently the basis for switching at least one of both hearing aids.
  • Radiotelephone When telephoning with a radiotelephone, be it a cordless phone according to the DECT standard or a mobile phone GSM or any other standard, can have at least one the two input signals an electromagnetically coupled Radio frequency signal include.
  • Speech signals disturbing couplings can be the phone operation with a digital phone due to the level difference at the left and right hearing aid detected and a corresponding Filtering be performed automatically.
  • the level can also be used with the level measuring device a predetermined periodic signal component of an input signal be determined.
  • a predetermined periodic signal component of an input signal be determined.
  • this is advantageous if the periodic signal component for an electromagnetic interspersed signal of a radiotelephone characteristically is.
  • a matched filter Detected signal portions of cordless and mobile phones and be used for binaural telephone identification.
  • a telephone signal with Help a binaural connection between a left and a a right hearing aid detected. It uses the fact that in a telephone situation level differences of AC signals between the hearing coils of the left and of the right hearing aid. To determine the level differences usually the entire frequency range is considered.
  • the transmitted Inductive inductively coupled into the respective hearing coil When telephoning with an analog telephone, the transmitted Inductive inductively coupled into the respective hearing coil.
  • the digital transmission interference signals directly or in the form of interference electromagnetically coupled into the hearing coil.
  • a technical realization of the hearing aid device according to the invention for automatic recognition of a telephone or Telephone situation is in the figure in the form of a principal Wiring diagram shown.
  • the binaurally supplied hearing impaired carries two hearing aids.
  • the left hearing aid has a hearing coil 1 and the right hearing aid a Hörspule 2.
  • a level meter 3 measures the absolute level of the audio coil signal Hearing coil 1.
  • a second level meter 4 measures the absolute level of the Hörspule signal the Hörspule 2.
  • Help of a subtracter 5 becomes the two level values of the level meter 3 and the level meter 4, a level difference determined.
  • This upper one Threshold can be specified arbitrarily. Is the level difference between both Hörspulensignalen greater than the upper Threshold 7, the telephone calls the hearing impaired, for example on his left ear. Accordingly, on the left Ear switched to the telephone situation 8.
