  • Patent number: 10448135
    Abstract: A case for a portable electronic device includes an enclosed, elongated space extending within the case from an opening in an interior surface of the case. The opening corresponds to the location of a microphone in the device. The enclosed space is tapered to an increasingly smaller cross-section as it extends away from the opening. A first edge of the enclosed space aligns along most of its length with an exterior surface of the case. A screen covers a second opening in the exterior surface of the case along the first edge of the elongated space and provides an acoustic resistance between the elongated space and air outside the case through the second opening. A gasket located at the first opening couples the elongated space to the microphone of the electronic device.

  • Patent number: 10397711
    Abstract: The present disclosure relates in a first aspect to a method of determining an objective perceptual quantity of a noisy speech signal using directional sound information. The method comprises steps of applying a noisy speech signal comprising a mixture of target speech and interfering noise to a first hearing instrument with an adjustable microphone arrangement and controlling the adjustable microphone arrangement to produce first and second directivity patterns exhibiting first and second directivity indexes, respectively, wherein said second directivity index is smaller than the first directivity index at one or more reference frequencies. First and second noisy speech segments are recorded from the adjustable microphone arrangement using the first and second directivity patterns, respectively, and at least one value of the objective perceptual quantity of the noisy speech signal is determined by comparing the first noisy speech segment and the second noisy speech segment.

  • Patent number: 9930460
    Abstract: A tinnitus method and device for providing relief to a person suffering from the disturbing effects of tinnitus is described. The method can be implemented entirely in software to spectrally modify an audio signal in accordance with a predetermined masking algorithm which modifies the intensity of the audio signal at selected frequencies. A predetermined masking algorithm is described which provides intermittent masking of the tinnitus wherein, at a comfortable listening level, during peaks of the audio signal the tinnitus is completely obscured, whereas during troughs the perception of the tinnitus occasionally emerges. In practice it has been found that such intermittent masking provides an immediate sense of relief, control and relaxation for the person, while enabling sufficient perception of the tinnitus for habituation and long term treatment to occur. Advantageously the predetermined masking algorithm is specifically tailored to the audiometric configuration of the person.

  • Patent number: 9894446
    Abstract: A hearing assistance system provides a hearing-aid wearer with one or more hearing aids and a portable device allowing for a wearer-driven directionality customization of the one or more hearing aids. The wearer indicates the locations of sound(s) of interest and/or noise source(s) using the portable device. The one or more hearing aids adjust the directionality of sound reception based on these wearer-indicated locations.

  • Patent number: 9877115
    Abstract: The use of a dynamic Relative Transfer Function (RTF) between two or more microphones may be used to improve multi-microphone speech processing applications. The dynamic RTF may improve speech intelligibility and speech quality in the presence of environmental changes, such as variations in head or body movements, variations in hearing device characteristics or wearing positions, or variations in room or environment acoustics. The use of an efficient and fast dynamic RTF estimation algorithm using short burst of noisy, reverberant mic recordings, which will be robust to head movements may provide more accurate RTFs which may lead to a significant performance increase.

  • Patent number: 9843861
    Abstract: A pair of earphones have microphone arrays each providing a plurality of microphone signals. A processor receives the microphone signals and applies a first set of filters to a subset of the plurality of microphone signals from each of the arrays, the first set of filters inverting the signals below a cutoff frequency, and provides the first-filtered signals and the remainder of the microphone signals from each of the arrays to a second set of filters. The processor uses the second set of filters to combine the signals to generate a far-field signal that is more sensitive to sounds originating a short distance away from the earphones than to sounds close to the earphones above the cutoff frequency, and omnidirectional below the cutoff frequency, determines a level of wind noise present in the microphone signals, and adjusts the cutoff frequency as a function of the determined level of wind noise.

  • Patent number: 9838808
    Abstract: A hearing aid comprises a microphone on a proximal side of a device housing and a loudspeaker which via a transmission channel is in open communication with a sound-emitting opening of the device. A sound processing device serves to generate sound received by the microphone to the loudspeaker in amplified form. The device housing is provided on a distal side with an optionally sealed battery chamber for receiving a battery therein. The transmission channel is at least almost wholly separated from the microphone acoustically in order to prevent acoustic feedback. The battery chamber comprises ventilation means for the purpose of increasing the lifespan of the battery.

  • Patent number: 9800981
    Abstract: The application relates to a hearing device comprising an input unit for providing first and second electric input signals representing sound signals, a beamformer filter for making frequency-dependent directional filtering of the electric input signals, the output of said beamformer filter providing a resulting beamformed output signal. The application further relates to a method of providing a directional signal. The object of the present application is to create a directional signal. The problem is solved in that the beamformer filter comprises a directional unit for providing respective first and second beamformed signals from weighted combinations of the electric input signals, an equalization unit for equalizing a phase (and possibly an amplitude) of the beamformed signals and providing first and second equalized beamformed signals, and a beamformer output unit for providing the resulting beamformed output signal from the first and second equalized beamformed signals.

  • Patent number: 9774965
    Abstract: An exemplary method for fitting a hearing device to a hearing device user performed by a fitting system operatively connected to but remote from the hearing device includes providing, to the hearing device, an adjustable parameter identified by a fitter using a fitting system and a specification comprising an allowed range for the adjustable parameter defined by the fitter using the fitting system. The method further includes transferring the adjustable parameter and the specification to a user interface operatively connected to the hearing device and located with the hearing device for use by the hearing device user, receiving an adjusted parameter value for the adjustable parameter adjusted by the hearing device user with aid of the user interface to be within the allowed range, and updating the adjustable parameter in a transfer function of the hearing device based on the adjusted parameter value.
