Definitions
- the present invention relates to a hearing aid, the to the spatial direction of an incoming sound signal adaptable is, with multiple microphones for recording input signals and a calculator for calculating at least a direction from which a specifiable sound signal arrives. Moreover, the present invention relates a corresponding method for adapting a hearing aid in at least one spatial direction of the sound incidence.
- blind source separation blind source separation
- BSS blind source separation
- the object of the present invention is therefore to a source separation despite head movements in an acceptable Time frame in hearing aids.
- this object is achieved by a hearing aid, that in the spatial direction of an incoming sound signal adaptable, with multiple microphones for recording of input signals and a calculating means for calculating at least one direction from which a specifiable Sound signal arrives, based on the input signals and a Position determining device for determining the current Position of the head of the hearing aid wearer, so with Help the position of the head in the calculator too calculating at least one direction can be influenced.
- the invention provides a method for adapting a hearing device to at least one spatial one Direction of an incident on the hearing aid sound signal by recording several microphone input signals, calculating the at least one direction from which a specifiable Sound signal arrives based on the microphone input signals, Change the position of the head of the hearing aid wearer and determine the current position of the head of the hearing aid wearer and influencing the calculated or calculated at least one direction from which the sound signal arrives, based on the current position of the head.
- the blind source separation can also in Hearing aids are used, which in certain situations the speech intelligibility can be drastically increased.
- the hearing aid has binaural supply a transmission device for wireless transmission of the Head position to the second hearing aid. That's enough, if a hearing aid with a position-determining device for Determining the head position is equipped.
- the transmission device is in many cases with binaural care anyway provided in the hearing aid.
- the position determination device can be designed in such a way that determines the position of the head based on the earth's magnetic field becomes. This has the advantage that not only a relative but also determines an absolute position of the head could be.
- the position determination device can be configured in this way be that head position with the help of an acceleration sensor is determined. This has the advantage that uses a common technology with rugged components can be.
- the invention is a Considered head movement in the adapted state of the hearing aid.
- a hearing aid as shown in the drawing features via several microphones M1, Mn.
- the signals of the microphones will be received by a preprocessing unit VV.
- a Position determination unit PB supplies the current head position also to the preprocessing unit VV.
- the preprocessed Signals of the preprocessing unit VV become parallel to an adaptive processing and demixing unit VE forwarded.
- the unit VE supplies the signals the different sources Q1, Qk.
- the head position of the position determination unit PB also to the processing and demixing unit VE to be delivered.
- Head Tracker As a position determining device PB so-called "Head Tracker", which, for example, the earth's magnetic field for position determination use, commercially available.
- the head tracker constantly indicates the current head position the pre-processing unit VV on. Preferably is at binaural supply this information wirelessly also to the Transfer hearing aid on the other side of the head.
- the pre-processing unit VV the current position with the microphone signals charged in such a way that in the case of Head movement the direction change of the microphones Reason the head movement is considered so that no new adaptation must be carried out 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 become. In this case, the adaptation process is the time dependency to take into account the signals.
