  • Patent number: 11882406
    Abstract: Hearing instruments, such as hearing aids, may improve a quality of presented audio through the use of a binaural application, such as beamforming. The binaural application may require communication between the hearing instruments so that audio from a left hearing instrument may be combined with audio from a right hearing instrument. The combining at a hearing instrument can require synchronizing audio sampled locally with sampled audio received from wireless communication. This synchronization may cause a noticeable delay of an output of the binaural application if the latency of the wireless communication is not low (e.g., a few samples of delay). Presented herein is a low-latency communication protocol that communicates packets on a sample-by-sample basis and that compensates for delays caused by overhead protocol data transmitted with the audio data.

  • Patent number: 11463816
    Abstract: A microphone assembly is provided, comprising a transducer assembly including a first enclosure defining a first acoustic volume and a Micro-Electrical-Mechanical-System (“MEMS”) microphone transducer disposed within the first enclosure. The microphone assembly also includes a second enclosure disposed adjacent to the first enclosure and defining a second acoustic volume in acoustic communication with the first acoustic volume, the second enclosure including an acoustic resistance, wherein the first and second acoustic volumes, in cooperation with the acoustic resistance, create an acoustic delay for producing a directional polar pattern. Circuitry comprising a shelving filter configured to correct a portion of a frequency response of the MEMS microphone transducer is also provided. In some embodiments, the circuitry is embedded within the transducer assembly or at least included within the microphone assembly.

  • Patent number: 11438710
    Abstract: Various implementations include control mechanisms for managing hearing aid usage. In some cases, an interface with a representation of the hearing aid in space is used to control audio functions in the device. In other cases, directionality of the device is controlled based upon the user's visual focus direction. In additional cases, the operating mode of the device is adjustable based upon the signature of a nearby acoustic signal.

  • Patent number: 11386283
    Abstract: A method operates an apparatus for tinnitus characterization, in which, in a first step, a broadband test signal having a number of signal frequencies is generated and compared with a tinnitus noise. The respective test signal is stored with an associated comparison result. A probability correlation for determining the tinnitus noise is established based on the stored test signals and comparison results. In a second step, the amplitudes of the individual signal frequencies of the test signal are varied. The first and second steps are performed repeatedly until the probability correlation reaches or exceeds a first threshold value. In a third step, the amplitudes of the individual signal frequencies of the test signal are varied with reference to the probability correlation.

  • Patent number: 11388528
    Abstract: A method operates a hearing system which has a hearing instrument worn in an ear. The method includes capturing a sound signal from an environment, processing the captured sound signal in dependence of a set of signal processing parameters, and outputting a processed sound signal to the user. The method further includes analyzing the captured sound signal to recognize own-voice intervals, in which the user speaks, analyzing the captured sound signal for an acoustic feature of the own voice of the user and/or analyzing a signal of a bio sensor. The bio sensor measures at least one non-acoustic vital function of the user and determines, from the acoustic feature and/or the non-acoustic vital function of the user, a measure of an emotional state of the user. A value of a signal processing parameter is adapted, within the own-voice intervals, to change the emotional state if a criterion is fulfilled.

  • Patent number: 11373668
    Abstract: An audio enhancement method includes receiving a first plurality of input signals representative of audio captured using an array of two or more sensors, the first plurality of input signals characterized by a first signal-to-noise ratio (SNR), with the audio being the signal-of-interest. The method also includes receiving a second input signal representative of the audio, the second input signal characterized by a second SNR. The second SNR is higher than the first SNR. The method further includes combining the first plurality of input signals and the second input signal to generate one or more driver signals, and driving one or more acoustic transducers using the one or more driver signals to generate an acoustic signal representative of the audio. The driver signals include spatial information derived from the first plurality of input signals, and are characterized by a third SNR that is higher than the first SNR.

  • Patent number: 11357982
    Abstract: At least one of the first or second hearing prostheses of a binaural hearing prosthesis system includes a dual-mode sound processing unit that is configured to selectively operate in a “sound processing mode” or in a “wireless streaming mode.” When operating in the sound processing mode, the dual-mode sound processing unit is configured to convert received sound signals into output signals for use in stimulating a first ear of a recipient. However, while operating in the wireless streaming mode, the dual-mode sound processing unit is configured to capture input signals (e.g., sound signals, data signals, etc.) and to encode those input signals for direct or indirect wireless transmission to the sound processing unit of the other hearing prosthesis of the binaural hearing system.
