A METHOD FOR OPERATING A HEARING SYSTEM AS WELL AS A HEARING SYSTEM
A method for operating a hearing system including a hearing device, a camera and an auxiliary device, the method including the steps of providing an input signal to the hearing device, capturing an image or a sequence of images of at least sections of a surrounding of a user wearing the hearing device, processing the image or the sequence of images in the auxiliary device) for obtaining consolidated data of a sound source being important for the user, transmitting the consolidated data to the hearing device, generating an output signal in the hearing device by processing the audio signal and by taking into account the consolidated data, and feeding the output signal to an output transducer of the hearing device. Thereby, a hearing system having improved capabilities is obtained.
SELF-CALIBRATING MICROPHONE AND LOUDSPEAKER ARRAYS FOR WEARABLE AUDIO DEVICES
A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.
Hearing instrument
A hearing instrument microphone device incudes at least two microphone sound ports (or sound inlets), a pressure difference microphone in communication with at least two of the sound ports and a pressure microphone in communication with at least one of the sound ports, wherein the acoustic centers of the pressure difference microphone and the pressure microphone essentially coincide.
Hearing device with sound source localization and related method
A hearing device includes: a processing unit; a transceiver connected to the processing unit and being configured for outputting a transceiver output signal representative of a first audio signal to form a first input signal for the processing unit; and a microphone connected to the processing unit for converting a second audio signal into a microphone output signal to form a second input signal for the processing unit; wherein the processing unit is configured to: estimate a time shift between the microphone output signal and the transceiver output signal, determine a time delay based on the time shift, and use the time delay to obtain a summing signal.
Hearing device with own-voice detection and related method
A hearing device includes: a first microphone and a second microphone for provision of a first microphone input signal and a second microphone input signal, respectively; a voice detector module configured to process the first microphone input signal and the second microphone input signal, the voice detector module configured to detect own-voice of a user of the hearing device; a processor configured to process the first microphone input signal and the second microphone input signal for provision of an electrical output signal based on the first microphone input signal and the second microphone input signal; and a receiver configured to convert the electrical output signal to an audio output signal; wherein the voice detector module is configured to notify a detection of the own-voice to the processor if at least two of a first voice criterion, a second voice criterion, and a third voice criterion are satisfied.
Hearing Eyeglass System and Method
The exemplary disclosure describes a hearing system e.g. comprising a Hearing Aid device comprising a cellphone and/or user worn device where some of the programs are carried out by components embedded onto the user worn device and some programs by hearing system components, e.g. which are inherently part of cellphones. The hearing system improves the intelligibility of voice messages arriving e.g. through the cellphone and/or other speaker, and/or e.g. via connected earphones and/or directly through the free air. The user can call diverse programs suitable for different situations, by using e.g. inertial sensors embedded in the hearing system, e.g. in the user worn system and/or e.g. are inherently part of the cellphone.
Hybrid audio delivery system and method therefor
Methods and systems to produce audio output signals from audio input signals. In one embodiment, a first portion of the audio input signals can be pre-processed, with the output used to modulate ultrasonic carrier signals, thereby producing modulated ultrasonic signals. The modulated ultrasonic signals can be transformed into a first portion of the audio output signals, which is directional. Based on a second portion of the audio input signals, a standard audio speaker can output a second portion of the audio output signals. Another embodiment further produces distortion compensated signals based on the pre-processed signals. The distortion compensated signals can be subtracted from the second portion of the audio input signals to generate inputs for the standard audio speaker to output the second portion of the audio output signals. In yet another embodiment, noise can be added during pre-processing of the first portion of the audio input signals.
Bilateral synchronized channel selection for cochlear implants
A bilateral hearing implant system has a left side and a right side. Left and right side filter bank pre-processors preprocess left and right microphone signals to generate band pass signals for each side. A bilateral signal processing arrangement processes the band pass signals in a time sequence of stimulation frames. The signal processing module includes a bilateral channel selection module synchronously selects for each stimulation frame a set of stimulation channels for each side based on spectral content of the band pass signals. Left and right side signal processing submodules process for each stimulation frame a limited subset of each side band pass signals corresponding to the selected stimulation channels to generate electrical stimulation signals.
HEARING AID SYSTEM WITH DIFFERENTIAL GAIN
A hearing aid and related systems and methods are disclosed. In one implementation, a hearing aid system may include a wearable camera; a microphone; and a processor. The processor may be programmed to receive images captured by the camera; receive audio signals representative of sounds received by the at least one microphone; determine a look direction of the user based on analysis of the images; determine an amplitude of a first audio signal associated with an individual or object in a region associated with the look direction of the user; determine an amplitude of a second audio signal from a region other than the look direction of the user; adjust the second amplitude in accordance with the first amplitude; and cause transmission of the second audio signal at the adjusted amplitude to a hearing interface device configured to provide sound to an ear of the user.
