Definitions

  • the invention relates to a method for improving a recording signal in a hearing system.
  • the user's perception of their own voice plays a particularly important role, since the subjective perception of their own voice, as perceived when wearing the hearing aid, significantly influences the user's acceptance of a hearing aid.
  • the perception of one's own voice is influenced on the one hand by the signal path of the hearing aid device, i.e. via a recording of the voice by the microphone system, a corresponding signal processing of the microphone signal in the hearing aid device and a playback by the loudspeaker or generally the electro-acoustic transducer of the hearing aid device, whereby the sound generated is delivered directly to the user's hearing.
  • a sound conductor intended for this supply be it an earpiece of a "Behind-The-Ear” instrument (BTE) or be it the output of an "In-The-Ear” or “Completely-In-the-Canal".
  • "-Instruments (ITE or CIC) usually largely close the ear canal, which can lead to an occlusion effect when the user speaks. This is primarily caused by sound waves from your own voice, which pass through Structure-borne sound transmission is primarily conducted via the jawbone to the ear canal and cannot escape to the outside due to the closure of the ear canal, which means that one's own voice is perceived as muffled when speaking.
  • a hearing device and a corresponding method for self-voice detection are disclosed.
  • a first microphone is provided for recording ambient sound and a second microphone for recording ear canal sound. From a comparison of the signals from the first microphone and the second microphone, it is concluded that the user of the hearing aid is speaking or that their own voice is present. If the presence of your own voice is detected, a directional microphone in particular is deactivated. In this way, the directional microphone is operated without interference, since the directional microphone would always be aligned undesirably to the frontal direction if one's own voice was present.
  • a hearing device which comprises at least two independent analysis devices, each of which is designed to obtain speech activity data based on a received audio signal, which is dependent on the speaker activity of the wearer of the hearing device.
  • a fusion device is designed to receive the voice activity data from the analysis devices and, based on the voice activity data, to recognize whether the wearer is currently speaking or not.
  • the US 2007/098192 A1 describes a method for operating a hearing aid in which, during the wearer's own speech activity, a directional characteristic of the microphones is adjusted in such a way that sound signals from the near field generally experience a significant attenuation, while the directivity for sound signals from the far field is maintained as unchanged as possible.
  • the aim of this is to ensure that the wearer's own speech signal is suppressed without affecting the other person's contribution to a conversation.
  • the EP 2 381 702 A2 teaches, for a hearing aid in which a directional cone is automatically aligned with vocal activity to amplify and improve the signal-to-noise ratio, to suppress or cancel such alignment when the voice is identified as the wearer's own voice.
  • the invention is based on the object of specifying a method which is intended to improve the sound of a recording signal in a hearing system during vocal activity for further processing as simply and efficiently as possible, particularly with regard to perception by a user.
  • the recording signal is to be understood as the signal into which the first signal from the first directional microphone, into which sound from the environment is converted with the spatial sensitivity specified by the set directional characteristic, is received for further signal processing.
  • the preferred direction of the first directional characteristic is here to be understood as the spatial direction in which the first directional microphone in this case has the greatest sensitivity, that is to say that in the case of a sound with a constant level that strikes the first directional microphone from different directions, upon impact The strongest signal level in the first signal is generated from the preferred direction.
  • the first directional characteristic preferably has axial or mirror symmetry, with the preferred direction lying on the axis of symmetry or in the plane of symmetry.
  • the frontal direction of the user is defined by the direction of view of his head, which runs parallel to the plane of symmetry of the head.
  • the first directional characteristic can be set in relation to the frontal direction of the user.
  • the first directional characteristic can preferably have a monotonous decrease in sound sensitivity in an angular range around the preferred direction, so that when adjusted by increasing the angle between the preferred direction and the frontal direction in the frontal direction, the attenuation of the sound sensitivity is achieved.
  • the invention is initially based on the consideration that any regulation or correction of the user's own voice in the recording signal, which is only carried out via the AGC or by adjusting the parameters for the compression, also has an impact on the perception of sound from the environment .
  • any regulation or correction of the user's own voice in the recording signal which is only carried out via the AGC or by adjusting the parameters for the compression, also has an impact on the perception of sound from the environment .
  • the user's own vocal activity could sometimes coincide with a useful signal formed by the speech of one of the conversation partners, this would result in rapid changes in the volume and/or dynamics of the useful signal formed by the speech of the conversation partner, as well as for the sound from the surrounding area.
  • the invention now makes use of the empirically detectable fact that due to the diffraction of the sound that leaves the mouth during speech activity, the sound of the user's own voice, which the user perceives in one ear, is essentially perceived as coming from the frontal direction.
  • the preferred direction of the first directional characteristic By adjusting the preferred direction of the first directional characteristic relative to the frontal direction of the user, it can be achieved that a smaller proportion of the user's own speech is included in the recording signal. For a pleasant hearing experience of one's own speech, an attenuation of 6 dB to 10 dB in the signal path in relation to the signal processing of other useful signals is usually sufficient. If the first directional characteristic has a monotonous decrease in sound sensitivity away from the preferred direction, a moderate deviation of the preferred direction of the first directional characteristic from the frontal direction is sufficient to attenuate the user's recorded speech signal by 6 dB to 10 dB.
  • the preferred direction of the first directional characteristic is adjusted at an angle between 5° and 20°, preferably between 5° and 10°, relative to the frontal direction of the user.
  • adjusting the preferred direction in the specified angular range is usually sufficient to achieve a sufficient attenuation of the signal component of the user's own language in the recording signal.
  • the perception of background noise in the listening situation which has a certain directional dependency, such as music from a localizable loudspeaker at a distance of several meters, is not really influenced, which means that the adjustment is even less noticeable for a user becomes.
  • the recording signal is monitored for a listening situation with a directional main sound source, with the preferred direction of the first directional characteristic being aligned to the frontal direction of the user without detecting a speech activity of the user when a listening situation with a directional main sound source is detected.
  • a directional main sound source is a sound source that has a significant directional dependence in relation to the sound level of other signal components, and whose sound level in the direction of the maximum is significantly above the level of other signal components regardless of their spatial direction (for example a loudspeaker box or the like).
  • the frontal direction of the user which usually essentially corresponds to the direction of his gaze, can be determined by further analysis of the recording signal, or also by a presetting in the hearing aid be determined based on the orientation of the first directional microphone when the hearing aid is worn properly.
  • the acoustic resolution - i.e. the signal-to-noise ratio - is achieved by appropriately adjusting the directional characteristic by adjusting the preferred direction towards the main sound source.
  • the recording signal is monitored for a listening situation corresponding to a conversation, with the preferred direction of the first directional characteristic being aligned to the frontal direction of the user without detecting a speech activity of the user when a listening situation corresponding to a conversation is detected.
  • a listening situation corresponding to a conversation possibly with little directed background noise, is a particularly common case for a listening situation with a main sound source, which is here formed by a conversation partner. If such a listening situation is initially recognized, it is assumed that the user's line of sight is usually in the direction of the currently active conversation partner if he or she is not speaking and therefore no own speech activity is recognized.
  • the binaural hearing system comprises a further hearing aid, in particular a hearing aid, wherein the further hearing aid comprises a second directional microphone, wherein the second directional microphone converts sound into a second signal which is included in the recording signal, and wherein when speech activity is detected of the user, the preferred direction of the second directional characteristic is adjusted relative to a frontal direction of the user in such a way that the second directional characteristic experiences an attenuation in the frontal direction.
  • the hearing system is designed as a binaural hearing system, in which a stereo playback signal is formed in particular from the recording signal, into which the first signal of the at least one hearing aid and the second signal of the further hearing aid are received, in such a way that to generate a first playback channel and of a second playback channel, signal components of both the first signal and the second signal are used.
  • a first playback channel can, on the one hand, only contain signal components of the first signal, the directional characteristic of which is influenced by the signal components of the second signal, or can directly contain signal components of the first signal and the second signal.
  • the user's own voice is perceived as coming from the frontal direction due to the lack of transit time difference in the signal components of the voice between the first signal and the second signal and is amplified accordingly.
  • the proposed method can reduce the signal components of the user's own voice in the recording signal particularly easily and without much effort in signal processing, with no noticeable changes in the signal level or in background noise recorded from the environment.
  • the preferred direction of the second directional characteristic is adjusted at an angle between 5° and 20°, preferably between 5° and 10°, relative to the frontal direction of the user.
  • the preferred directions of the first directional characteristic and the second directional characteristic are expediently adjusted in the specified angular range.
  • adjusting the preferred direction in the specified angular range is usually sufficient to achieve a sufficient attenuation of the signal component of the user's own language in the recording signal.
  • the perception of background noise in the listening situation which has a certain directional dependency, such as music from a localizable loudspeaker at a distance of several meters, is not really influenced, which means that the adjustment is even less noticeable for a user becomes.
  • the recording signal is monitored for a listening situation corresponding to a conversation, with the preferred direction of the second directional characteristic being aligned to the frontal direction of the user when a conversation partner's speech activity is detected.
  • the preferred directions of the first directional characteristic and the second directional characteristic are expediently aligned with the frontal direction of the user. Particularly in the case of a binaural hearing system with a rich spatial sound, particularly good intelligibility of the conversation partner's speech signal can be achieved in the hearing situation mentioned with little effort in signal processing.
  • the preferred directions of the first directional characteristic and the second directional characteristic are adjusted relative to the frontal direction of the user in such a way that the preferred directions the first directional characteristic and the second directional characteristic, starting as vectors from the respective hearing aid, cross each other.
  • the adjustment is carried out symmetrically, that is, the preferred direction of the first directional characteristic and the preferred direction of the second directional characteristic are each adjusted inwards or towards each other by the same angular amount with respect to the frontal direction.
  • the signal component of the user's own voice which is included in the recording signal, is reduced via the shading effect that the head exerts on the sound of the voice when the directional characteristics are aligned accordingly.
  • the directional characteristics cross, sudden interjections from a conversation partner standing at the front can continue to be recorded almost unaffected.
  • the recording signal is broken down into a plurality of frequency bands, and when a speech activity of the user is detected, a preferred direction of the first directional characteristic and/or a preferred direction of the second directional characteristic is adjusted in at least one frequency band relative to the frontal direction of the user.
  • the directional characteristics only appear in those Frequency bands adjusted relative to the frontal direction, in which either an excessive signal component in the recording signal is perceived by the user as particularly unpleasant, or which have a particularly high directionality in the speech signal and are therefore particularly easy to influence by adjusting the directional characteristic, this can be done in the Signal processing of the other frequency bands save resources.
  • the invention further mentions a binaural hearing system with two hearing aids, in particular hearing aid devices, each of which has at least one directional microphone, which is set up to carry out the method described above.
  • the advantages stated for the method and its further developments can be transferred analogously to the binaural hearing system.
  • FIG. 1 A top view shows schematically a user 1 of a binaural hearing system 2, which includes two hearing aids 6, 7 designed as hearing aids 4, 5.
  • the left hearing aid 6 has a first directional microphone 8 with a first directional characteristic 10, which is symmetrical with respect to a preferred direction 12.
  • the right hearing aid 7 has a second directional microphone 14 with a second directional characteristic 16, which is symmetrical with respect to a preferred direction 18.
  • the hearing situation 20 of the user 1 of the binaural hearing system 2 is given by a conversation with conversation partners 22 to 26.
  • the current conversation situation is now such that the user 1 aligns his frontal direction 28 (which is given by the direction of vision of the head) towards the conversation partner 22 for better listening.
  • the interlocutor 22 is the main actor in the present conversation situation, and the other interlocutors 23 to 26 only make occasional objections, the preferred direction 12 of the first directional characteristic 10 and the preferred direction 18 of the second directional characteristic 16 are aligned in the frontal direction 28 of the user 1 , whereby the speech signal of the conversation partner 22 can be perceived particularly well via the binaural hearing system 2.
  • Frontal perception is also due to the fact that the sound of one's own speech arrives at both ears without a difference in transit time, so that the symmetrical perception creates the sensation of a sound hitting frontally.
  • the directional characteristics 10, 16 of the two directional microphones 8, 14 of the binaural hearing system 2 are adjusted against the frontal direction 28 when the user 1 is speaking. This is in Fig. 2 shown.
  • the preferred direction 12 of the first directional characteristic 10 of the first directional microphone 8 is tilted slightly outwards with respect to the frontal direction 28 when the user 1 is speaking.
  • the directional characteristics 10, 16 form a type of channel 30 from the user 1 to the conversation partner 22, in which the sound sensitivity of the binaural hearing system 2 is reduced.
  • the sound 32 of the user 1's own language initially propagates in this channel 30 and is guided to the directional microphones 8, 14 by diffraction. Since the preferred directions 12, 18, which represent the direction with the greatest sound sensitivity for the directional characteristics 10, 16, are now adjusted relative to the frontal direction 28 of the user 1, the sound 32 of the user 1's own language experiences its input into a recording signal of the binaural hearing system 2 a slight attenuation.
  • FIG. 3 An inventive adjustment of the directional characteristics 10, 16 relative to the frontal direction 28 of the user 1 during one's own speech activity is shown schematically in a top view in Fig. 3 shown.
  • the first directional characteristic 10 of the first directional microphone 8 is not adjusted outwards, i.e. away from the frontal direction 28 of the user 1, but rather inwards "inwards” towards one another, so that the preferred direction 12 of the first directional characteristic 10 crosses the frontal direction 28.
  • the attenuation of the signal component that enters a recording signal of the binaural hearing system 2 occurs primarily as a result of shadowing effects caused by the head of the user 1.
  • the directional characteristics 10, 16 are set so that the areas with particularly high sound sensitivity are already partially covered ("shadowed") by the user's head, so that the sound hitting the directional microphones 8, 14 from the front is also the user's own speech This causes the recording signal to be attenuated.
  • the variant shown here also has the advantage that the conversation partner 22 is still well detected by the directional characteristics 16, 10 of the directional microphones 8, 14, i.e.
  • the sound sensitivity of the directional microphones 8, 14 in an immediate environment of the conversation partner 22 is still good enough at a usual conversation distance of 0.5 to 1.5 m to include any spontaneous replies and/or interjections of the conversation partner 22 with a sufficiently high signal level in the recording signal of the binaural hearing system 2.
  • Fig. 4 the sequence of a method 40 for improving a recording signal 42 in a binaural hearing system 2 is shown in a block diagram.
  • the two directional microphones 8, 14 of the hearing aids 4, 5 generate a first signal 44 or a second signal 46 from a sound 43, which are included in the recording signal 42.
  • the recording signal 42 is broken down into a plurality of frequency bands 48 and monitored for a listening situation 20 corresponding to a conversation based on the sound levels in the frequency bands 48 and based on the correlations in the signal components of the frequency bands 48. If this hearing situation 20 is recognized, monitoring of the user's speech activity 50 is carried out in some frequency bands 48.
  • the first directional characteristic 10 of the first directional microphone 8 and the second directional characteristic 16 of the second directional microphone 14 are directed against the frontal direction of the user in the manner described above adjusted.
  • the directional characteristics 10, 16 are aligned in the frontal direction in the manner explained above. In particular, this can also be done depending on a recognized speech activity 54 of the conversation partner, i.e. the directional characteristics 10, 16 in the relevant frequency bands towards the frontal direction are only adjusted when the signal coming from the direction of the conversation partner 22 has a correspondingly appreciable level, so that speech activity 54 is thereby detected.
  • the recording signal 42 formed by the frequency bands 48 can now be further processed in accordance with the applications intended for the binaural hearing system 2.
  • the two hearing aids 6, 7 each include a substantially omnidirectional individual microphone 55 and 56 (see Fig. 4 ).
  • the two directional microphones 8, 14 are each formed by interconnecting the two individual microphones 55, 56 (illustrated by a dashed connecting line in Fig. 4 ), whereby the first directional characteristic 10 for the first hearing aid 6 and the second directional characteristic 16 for the second hearing aid 7 arise or result from separate signal processing of the signals from the first and second individual microphones 55 and 56, respectively.
