Definitions

  • the present invention relates to a hearing device which is adaptable to the spatial direction of an incoming sound signal, comprising a plurality of microphones for receiving input signals and a computing device for calculating at least one direction from which a predeterminable sound signal arrives. Moreover, the present invention relates to a corresponding method for adapting a hearing device to at least one spatial direction of the sound incidence.
  • BSS blind source separation
  • a portable sound reproduction device for generating a three-dimensional sound impression For example, a portable sound reproduction device for generating a three-dimensional sound impression is known.
  • a device for determining the head orientation is integrated in a portable sound reproduction device, in particular headphones or a helmet with integrated sound generators.
  • the virtual sound waves do not follow the head movements of the listener and the artificially induced three-dimensional sound perception corresponds to the natural sound perception in real stationary sound sources.
  • WO 99/43185 A a binaural digital hearing aid system.
  • the hearing aids used in this case each have a transmission device for wireless transmission.
  • the object of the present invention is therefore to be able to perform source separation despite head movements in a reasonable time frame in hearing aids.
  • this object is achieved by a hearing aid according to claim 1.
  • the blind source separation can also be used in hearing aids, which can be increased dramatically in certain situations, the speech intelligibility.
  • the hearing device preferably has a transmission device for the wireless transmission of the head position to the second hearing device.
  • a transmission device for the wireless transmission of the head position to the second hearing device.
  • the transmission device is provided in many cases with binaural supply anyway in the hearing aid.
  • the position determining device can be designed so that the position of the head is determined based on the geomagnetic field. This has the advantage that not only a relative but also an absolute position of the head could be determined.
  • the position-determining device can be configured such that the head position is determined with the aid of an acceleration sensor. This has the advantage that a common technology with robust components can be used.
  • a head movement in the adapted state of the hearing aid is taken into account.
  • the current head position is already taken into account during the adaptation process in the hearing device. As a result, the time for adjusting the hearing device can be further reduced.
  • a hearing aid as shown in the drawing has a plurality of microphones M1, Mn.
  • the signals of the microphones are recorded by a preprocessing unit VV.
  • a position determination unit PB also supplies the current head position to the preprocessing unit VV.
  • the preprocessed signals of preprocessing unit VV are sent in parallel to an adaptive processing and demixing unit VE forwarded.
  • the unit VE supplies the signals of the various sources Q1, Qk.
  • the head position of the position determination unit PB can also be supplied to the processing and demixing unit VE.
  • head trackers As a position determining device PB so-called "head trackers", for example, use the earth's magnetic field for position determination, commercially available. In the case of use, the head tracker constantly passes on the current head position to the preprocessing unit VV. In the case of binaural supply, this information is preferably also transmitted wirelessly to the hearing device on the other side of the head.
  • the current position is offset with the microphone signals such that in the case of a head movement, the change in direction of the microphones due to the head movement is considered so that no new adaptation must be performed as long as the external speakers or sound sources do not change their positions , If the head movement already takes place during the adaptation, the head movement must be registered accordingly. In this case, the adaptation process must take into account the time dependency of the signals.
