The electronic circuit is configured to select at least one mandrel zone in response to a component of the return optical signal from the at least one mandrel zone, and to detect an acoustic signal incident on the mandrel in response to the component of the return optical signal. | 2022-01-20 |
20220021984 | HEARING AID - A hearing aid, in particular a BTE hearing aid, includes a base part and an ear hook which can be attached to the base part. In an assembled state, the base part and the ear hook are connected by a nozzle and a receptacle. A sound channel runs through the nozzle. The nozzle has a circumferential outer wall and the receptacle has a circumferential inner wall. In the assembled state, a circumferential sealing ring having a thickness is disposed between the outer wall and the inner wall. The sealing ring lies in particular in an annular groove and the inner wall preferably has two reduction sections which compress the sealing ring. | 2022-01-20 |
20220021985 | Selectively conditioning audio signals based on an audioprint of an object - A hearing aid system for selectively conditioning audio signals associated with a recognized object may include at least one processor. The processor may be programmed to receive audio signals acquired by a wearable microphone; analyze the received audio signals to obtain an isolated audio stream associated with a sound-emanating object in the environment of the user; determine an audioprint from the isolated audio stream; and use the audioprint to retrieve from a database information relating to the particular sound-emanating object. Based on the retrieved information, the processor may cause selective conditioning of at least one audio signal received by the wearable microphone from a region associated with the at least one sound-emanating object; and cause transmission of the at least one conditioned audio signal to a hearing interface device configured to provide sounds to an ear of the user. | 2022-01-20 |
20220021986 | METHOD FOR OPERATING A HEARING SYSTEM, HEARING SYSTEM AND HEARING DEVICE - A method operates a hearing system having a hearing device and modifies an input signal for the purpose of sound output to a user and, applies multiple algorithms with a respective potency, as a result of which a respective algorithm is applied with a present potency in a present situation. The hearing system recurrently receives a report from the user indicating that the user is dissatisfied with the sound output in the present situation. The hearing system has a database, containing multiple weights for each algorithm, to rate a change of the potency. If a report is received, each of the algorithms is rated using the weights to ascertain an individual-case relevance for each of the algorithms, to assess the effect of a change of the potency. Multiple individual-case relevances are combined to form a relevance value for each algorithm, the relevance values are compared with one another. | 2022-01-20 |
20220021987 | METHOD, HEARING SYSTEM AND COMPUTER READABLE MEDIUM FOR IDENTIFYING AN INTERFERENCE EFFECT - A method is specified for identifying an interference effect. The hearing system includes a hearing device, which is worn by a user for sound output to the user. The hearing system is configured to recurrently receive a report from the user such that an interference effect is present in the sound output. If the user reports an interference effect in a present situation, multiple features of the present situation are ascertained and stored as a feature set. An identification unit compares multiple stored feature sets to one another and ascertains those features which correspond in the multiple feature sets and which are then assumed as characteristic features of the interference effect, so that the identification unit identifies the interference effect on the basis of the characteristic features. | 2022-01-20 |
20220021988 | SELECTIVE MODIFICATION OF BACKGROUND NOISES - A hearing aid system for selective modification of background noises may include at least one processor. The processor may be programmed to receive a plurality of images from an environment of a user captured by a wearable camera during a time period and receive an audio signal representative of sounds acquired by a wearable microphone during the time period. The processor may determine that at least one of the sounds was generated by a sound-emanating object in the environment of the user, but outside of a field of view of the wearable camera and retrieve from a database information associated with the sound-emanating object. Based on the retrieved information, the processor may cause selective conditioning of audio signals acquired by the wearable microphone during the time period and cause transmission of the conditioned audio signals to a hearing interface device configured to provide sounds to an ear of the user. | 2022-01-20 |
20220021989 | EAR-WORN ELECTRONIC DEVICE INCORPORATING MAGNETICALLY COUPLED FEED FOR AN ANTENNA - Embodiments are directed to an ear-worn electronic device configured to be worn by a wearer. The device comprises an enclosure configured to be supported at, by, in or on the wearer's ear. A processor is disposed in the enclosure. A speaker or a receiver is coupled to the processor. A radio frequency transceiver is disposed in the enclosure and coupled to the processor. An antenna is disposed in or on the enclosure. A magnetically coupled feed arrangement comprises a separable transformer. The separable transformer comprises a first coil coupled to the antenna and a second coil coupled to the transceiver, wherein the second coil is physically and electrically separated from the first coil. The feed arrangement is configured to feed the antenna via mutual inductance between the first and second coils | 2022-01-20 |
