Definitions

  • the present invention relates to a hearing device with a direction detection device for detecting a Direction, from the sound source from a sound signal the listener device arrives, and a signal processing device for processing the incoming sound signal depending on the detected direction.
  • a direction detection device for detecting a Direction
  • the present invention relates to a corresponding Method for operating such a hearing device.
  • Hearing aids often have directional microphones with which the Sound recording can be designed direction-dependent. So for example, it is helpful for noise suppression, the sound of a source of interference that is in a certain Direction is registered to dampen as much as possible.
  • a generic earphone device is for example from the Document DE 197 21 157 known.
  • document WO 00/19770 describes Hearing aid and method for processing microphone signals in a hearing aid, where a noise canceling is provided in numerous listening situations.
  • the hearing aid has a signal analysis unit that has at least one property the directional gain or attenuation to change.
  • the signal analysis unit takes one Directional analysis of the microphone signals.
  • the can Strengthen signal components of the microphone signals in several Direction classes are divided.
  • the noise to suppress a source of interference.
  • the object of the present invention is therefore to to provide a hearing device that the respective Carrier z. B. protects better in a dangerous situation. Furthermore, a corresponding method for operating an earphone device.
  • this object is achieved by a hearing device with a direction detection device for detecting a direction from a sound source Sound signal arrives at the earphone device, and a Signal processing device for processing the incoming Sound signal as a function of the detected Direction, and a noise classification device for Classifying the sound signal arriving from the sound source in signal classes, so that the incoming sound signal in the signal processing device also in dependence of the signal class is processable.
  • the invention provides a method for Operate a hearing device by detecting a Direction, from the sound source of a sound signal arrives, and processing the incoming sound signal in Dependence on the detected direction, classify of the incoming sound source from the sound signal in signal classes and processing the incoming sound signal also depending on the signal class.
  • the direction detection device comprises in the hearing device is an adaptive directional microphone.
  • the directional characteristic of the directional microphone for example, depending on be adjusted by the signal class. alternative or additionally, the directional characteristic of the microphone but also depending on the frequency of an incoming Sound signal can be adjusted. This can be the one or more notches or notches of a directional microphone characteristic depending on the signal class and / or Frequency can be turned in a desired direction. At default Signal classes that signal a danger, for example, thus can the interference suppression in their quality be varied accordingly.
  • the hearing device may be a signal output device for Output of a signal over the signal class of the incoming Have sound signal to the carrier of the receiver device. Likewise, from this signal output device, a signal about the direction of the incoming sound signal to the carrier the hearing device are output.
  • the issued Signal can be a voice signal or a tactile stimulus, e.g. a vibration, his. This makes it possible, for example, with a language generated in a hearing aid Hearing aid wearers in a dangerous situation an aid in the form of additional information. These Additional information can be, for example, the type of hazard as well as their direction.
  • the integration a corresponding information-providing system in, for example a hearing aid has the advantage of the loudness-fair Presentation of a warning. This means that ensured can be that the information arrives at the user, in contrast to the sound of a bicycle or moped, which where appropriate, has not been sufficiently reinforced.
  • the earphone device as a hearing aid is in principle also an embodiment as Headphone or headset conceivable. That's it, for example possible for the wearer of a headphone to scream a baby is alerted.
  • a hearing aid according to the invention comprises, as in the figure is shown schematically, a directional microphone RM.
  • This Directional microphone RM can be used in the binaural supply Microphones can be realized from both sides.
  • the directional microphone RM supplies to a signal processing device VE In addition to the acoustic signals and a direction information. This can be used to the directional characteristic RC, which is indicated by dashed lines in the figure, the Align directional microphone RM in the desired manner.
  • the directional characteristic RC has one or more indentations or notches.
  • a Notch N is drawn.
  • the sensitivity of the directional microphone RM is the lowest.
  • the direction information could be in Quadrants are quantized. Accordingly, for example according to the present figure, the direction of Source of interference Q with "back left".
  • the directional microphone RM delivers the recorded sound signal possibly also preprocessed to a noise classifier GK. This divides the received signals into several Signal classes. Because of this, information about present dangers are obtained. As signal classes are for example conceivable: baby crying, bicycle bells, streetcar noise, etc. The recorded sound signals can also be classified only in terms of loudness. Because of this classification information, the hearing aid may HG or its signal processing device VE detected be, from which direction if necessary danger threatening.
  • the signal generator SG can also activate a vibrator integrated into the hearing aid HG, if the signal of a certain signal class, z. B. bicycle bells, exceeds a certain predetermined threshold or gets louder as the bike gets closer.
  • a vibrator integrated into the hearing aid HG if the signal of a certain signal class, z. B. bicycle bells, exceeds a certain predetermined threshold or gets louder as the bike gets closer.
  • the signal output of the hearing aid HG can also be used over others Paths take place. So it is conceivable that the hearing aid HG the gained information about direction and type of noise transmitted to a mobile phone and there a corresponding Vibrating alarm or the like triggers.
