Definitions

  • the invention relates to a method for focusing a beamformer of a hearing instrument.
  • Hearing instruments can, for example, be designed as hearing aids worn on or in the ear.
  • a hearing aid is used to supply a hearing-impaired person with acoustic ambient signals that are processed and amplified to compensate for or treat the specific hearing impairment. It essentially consists of one or more input transducers, a signal processing device, an amplification device, and an output transducer.
  • the input transducer is usually a sound receiver, e.g., a microphone, and/or an electromagnetic receiver, e.g., an induction coil.
  • the output transducer is usually implemented as an electroacoustic transducer, e.g., a miniature loudspeaker, an electromechanical transducer, e.g., a bone conduction receiver, or a stimulation electrode for cochlear stimulation. It is also referred to as a receiver.
  • the output transducer generates output signals that are transmitted to the patient's ear and are intended to produce an auditory perception in the patient.
  • the amplifier is usually integrated into the signal processing device.
  • the hearing aid is powered by a battery integrated into the hearing aid housing.
  • the essential components of a hearing aid are usually arranged on or connected to a printed circuit board (PCB).
  • PCB printed circuit board
  • the problem is determining the direction in which the beamformer should be directed and finding the optimal width, or aperture angle, of the beam.
  • the problem is to find the spatial direction in which the directional microphone array should have the highest sensitivity and the angle, or aperture angle, over which the sensitivity should be increased. It is obvious that better directionality and sensitivity can be achieved by directing the beam as precisely as possible toward the acoustic source of interest and focusing it as tightly as possible.
  • interesting acoustic sources can primarily be speakers or speech signals, but there are also a number of other possibilities, such as music or cue signals.
  • a hearing aid uses a method for acoustic source separation. Using a binaural microphone array, the spatial direction of an acoustic source is determined. A binaural receiver array then generates an acoustic output signal dependent on the determined direction.
  • a hearing aid that determines the spatial direction of acoustic signals. Based on the determined spatial-acoustic information, the acoustic environment is then classified, and the transfer characteristics of the signal processing are adjusted depending on the classification.
  • a hearing aid determines the spatial direction of acoustic sources. A beamformer is then directed toward a determined direction to focus on the acoustic source in question.
  • the spatial direction can be determined based on, among other things, the user's head orientation or line of sight.
  • a hearing aid uses a method for "blind source separation" of different acoustic sources. The user can select the various detected sources one after the other by pressing a switch.
  • SpeechFocus a process known from Siemens hearing aids, automatically scans the acoustic environment for speech components. Once speech components are identified, their spatial direction is determined. The amplification of acoustic signals from that direction is then increased compared to signals from other directions.
  • the simplest way to shape the beam is to assume that the desired source or speaker is located directly in front of the hearing instrument user and that the beam should therefore be directed forward, with the beam direction being changed by head movements of the user.
  • the hearing instrument can direct the beam in a desired direction using an algorithm for processing the microphone signals, regardless of the orientation of the head.
  • the beam direction can be controlled, for example, by a remote control.
  • the disadvantage is that the user cannot hear or can hardly hear sources outside the beam and thus cannot register them. Furthermore, having to control the beam via remote control is uncomfortable and unintuitive for the user.
  • the hearing aid can automatically analyze the direction of potentially interesting acoustic sources and automatically align the beam in that direction, as in the SpeechFocus process from Siemens.
  • this can be confusing for the user, as the hearing aid can automatically and potentially unexpectedly jump between different sources without any user intervention.
  • a continuously adapting beamformer alters the binaural "cues," making it difficult or even impossible for the user to locate the source of interest.
  • the beam width is usually constant or can be manually adjusted by the user between different preset opening angles.
  • a known method involves classifying the audio signal before localizing an audio source.
  • the classification can be based on features such as harmonic signal components or the presence of formants.
  • the subsequent localization benefits from the previous classification.
  • the object of the invention is to enable an automatic adaptation of the beam width and/or the beam direction, which can be used comfortably and intuitively, which avoids unexpected focusing of the beam without intervention by the hearing instrument user, and which makes it possible to make acoustic sources outside the beam known to the user in a simple and easy-to-use manner.
  • Directivity is a property of the beamformer that can be represented as a metric, the higher the directivity the beamformer is focused, i.e., the smaller the solid angle of the beam.
  • acoustic source such as a speaker
  • suitable tolerance values or thresholds such as at least 15° rotation, must be specified in order to distinguish unintentional or irrelevant minimal head movements from relevant head movements.
  • Manual triggering of focusing for example, by pressing a button on the hearing instrument or using a remote control, is not required, which significantly contributes to the practicality and comfort of the method.
  • the probability is increased that the method actually focuses on a source of interest to the user, and not on a randomly set focus spatial angle depending on the source.
  • the focus is better aligned with the source of interest to the user. This subsequently enables sharper focusing due to a narrower focus solid angle, thus increasing directionality. Increasing directionality, in turn, results in a further enhancement of the source signal of interest.
  • a further advantageous embodiment is that the method is only performed if a head movement was detected before the absence of head movement was detected. This prevents, for example, automatic focusing from occurring even though the user has not turned toward an acoustic source, for example because the source is non-acoustic or because the user does not want to devote their increased attention to any one source.
  • a further advantageous embodiment is that the method is only performed if an acoustic source was detected within the focus solid angle before focusing. This prevents focusing despite the absence of acoustic sources, which would obviously be impractical.
  • Figure 1 is a schematic view of a user 1 with left hearing instrument 2 and right hearing instrument 3 in plan view.
  • the microphones of the left and right hearing instruments 2, 3 are each combined to form a directional microphone arrangement, so that it is possible to direct the respective beam essentially either forwards or backwards as seen from user 1.
  • a wireless link e2e
  • This essentially enables directions to the right and left as seen from user 1 as additional beam directions of the arrangement.
  • the automatic focusing of the beam can be carried out both for each monaural hearing instrument individually (front/back) and for the binaural arrangement (right/left) together.
  • the left and right hearing instruments 2, 3, including the essential signal processing components, are shown schematically.
  • the hearing instruments 2, 3 are constructed identically and may differ in their external shape to accommodate their respective use on the left or right ear.
  • the left hearing instrument 2 comprises two microphones 4, 5, which are arranged spatially separately and together form a directional microphone arrangement.
  • the signals from the microphones 4, 5 are processed by a signal processing device 11, which emits an output signal via the receiver 8.
  • a battery 10 supplies power to the hearing instrument 2.
  • a motion sensor 9 is also provided, the function of which in the automatic focusing process will be explained further below.
  • the right hearing instrument 3 comprises the microphones 6, 7, which are also combined to form a directional microphone arrangement.
  • FIG. 3 The essential signal processing components of the automatically focusing beamformer are shown schematically.
  • the signals from microphones 4 and 5 of the left hearing instrument 2 are processed by the beamformer to create a beam directed straight forward (0°, "broadside") as seen from the user's perspective, which has a variable beam width.
  • Variable beam width is synonymous with variable directionality (a smaller beam width means greater directionality and vice versa, with higher directionality being synonymous with greater directional dependence).
  • the beamformer is constructed in a conventional manner, for example, as an array of fixed beamformers, as a mixture of a fixed beamformer with a direction-independent omnidirectional signal, as a beamformer with variable beam width, etc.
  • Output signals of the beamformer 13 are the desired beam signal, which contains all acoustic signals from the direction of the beam, the direction-independent omni signal (which contains all acoustic sources in all directions with under-distorted binaural cues) and the anti-signal, which contains all acoustic signals from directions outside the beam.
  • the three signals are fed to the mixer 19 and, in parallel, to the source detectors 15, 16, 17.
  • the source detectors 15, 16, 17 continuously determine the probability (or a comparable measure) that an acoustic source of interest, for example a speech source, is present in the three signals.
  • the motion sensor 9 is designed to detect head movements of the hearing instrument user, including rotation, and also to determine the extent of each movement.
  • a dedicated hardware sensor of the conventional type is the fastest and most reliable way to detect head movements.
  • other options for detecting head movements are also available, for example, based on a spatial analysis of the acoustic signals or using additional alternative sensor systems.
  • a head movement detector 14 analyzes the signals from the motion sensor 9 and uses them to determine the direction and extent of head movements.
  • All signals are fed to the focus control 18, which determines the beam width based on the signals. The determined beam width is then fed by the focus control 18 to the beamformer 13 as an input signal.
  • the focus control also controls the mixer 19, which mixes the three previously explained signals (omni, anti, beam) and forwards them to a hearing instrument signal processor 20.
  • the hearing instrument signal processor 20 the acoustic signals are further processed in the manner customary for hearing instruments and amplified, then output to the receiver 8.
  • the receiver 8 generates the acoustic output signal for the hearing instrument user.
  • the focus control 18 is preferably designed as a finite state machine (FSM), the finite states of which will be explained further below.
  • FSM finite state machine
  • the three signals (Omni, Anti, Beam) are mixed by the mixer 19 so that the user receives a natural-sounding spatial signal. This also includes ensuring smooth transitions rather than abrupt ones. Further processing steps take place in the hearing instrument signal processing 20, which primarily serve to compensate for or treat the user's hearing impairment.
  • FIG 4 An exemplary situation is shown schematically. It shows hearing instrument user 1 with left and right hearing instruments 2, 3 in a top view. An acoustic source 21 is located directly in front of user 1, toward which user 1 is looking. The beam of the respective hearing instrument 2, 3 is focused on acoustic source 21 by reducing the beam width to an angle of ⁇ 1. Thus, the additional acoustic source 22 lies outside the beam, but would be within a beam with a beam width of ⁇ 2. The additional acoustic source 23 lies even further outside the beam and is located almost next to user 1.
  • the finite states of the Finite State Machine are explained.
  • the FSM starts in the "Omni" state 40 (no directionality, the mixer outputs the Omni signal), in which the hearing instrument user hears normally and independently of direction. In this state, they are able to localize acoustic sources normally. They can move and turn their head in a normal and natural manner, for example, to search for an acoustic source of interest, such as a speaker.
  • the FSM enters the "Focusing" state 42, and the directionality of the beamformer is gradually increased (the beam width is reduced, and a correspondingly more direction-dependent signal is output to the user). This increases the proportion of the source signal in the beam signal, and the mixer passes on the filtered signal by outputting exclusively or primarily the beam signal.
  • the maximum directionality (minimum beam width) is reached, which corresponds to the previous Figure 5 and Figure 8 If the beam width corresponds to the state described above, the proportion of the source signal of interest in the beam signal cannot be increased any further. The directionality is not further changed (beam width is not further reduced), and the FSM exits loop 43 and enters the "Focused" state 44. In the "Focused" state 44, the automatic beam control continuously monitors the user's head movements using the motion sensor (loop 47). As long as no head movements are detected, the FSM remains in the "Focused" state 44.
  • the system continuously monitors whether any acoustic sources of interest are present outside the beam in the Omni and Anti signals. If a new source is detected, the FSM switches to the "Glimpsing" state 45. In the "Glimpsing" state 45, a small portion of the Omni signal, which contains the potential additional source, is mixed into the output signal for the user by the mixer. This alerts the user that another source is present. If the user does not turn toward this new source, they do not move their head.
  • the automatic focus control detects this with the help of the motion sensor and, after a certain period of time, adjusts the portion of the Omni signal back to zero (fade out), allowing the user to fully concentrate on the focused signal again.
  • the described "glimpsing" is performed every time a new source appears in the acoustic environment or when the acoustic environment changes significantly.
  • the head movement is detected and the focus control immediately switches to the Omni signal, ie the beam width is greatly enlarged and/or the mixer outputs the omni signal additionally or exclusively. This is represented in the figure by element 46.
  • the Omni signal allows the user to survey the acoustic environment with all undistorted spatial cues that are distorted or missing in the beam signal. This allows the user to localize acoustic sources normally. As soon as the user focuses on a different acoustic source, which is similar to the previously explained Figure 7 , the FSM returns to the focusing state 42. Beam focusing then begins again.
  • the method explained above enables a function that closely mimics the human ability to focus on different sources by combining the various beamformer signals with the head movement detector.
  • Head movement is used to provide natural feedback for automatic focusing and rapid defocusing on a target to control the beamformer. Focusing occurs gradually when the user is not moving their head. Defocusing upon head movement, or the transition from the beam signal to the omni-signal, occurs quickly to quickly provide an undistorted signal with all spatial information in the event of changes.
  • the glimpsing function allows the user to remain focused on one source while maintaining an overview of new sources and changes.
  • an acoustic source for example a speaker
