A hearing system includes a processing device, a hearing aid adapted to be worn by a user, and a data logger. The hearing aid includes an input transducer providing an electric input signal representing sound in the environment of the user, and a hearing aid processor executing a processing algorithm in dependence of a specific parameter setting. The data logger stores time segments of said electric input signal, and data representing a corresponding user intent. The processing device comprises a simulation model of the hearing aid. The simulation model is based on a learning algorithm configured to provide a specific parameter setting optimized to the user's needs in dependence of a hearing profile of the user, the logged data, and a cost function. A method of determining a parameter setting for a hearing aid is further disclosed.

A method fits a digital hearing aid having an input transducer, a signal processing device and an output transducer. The signal processing device is configured to form an evaluation unit, a comparator unit, and a pre-amplification unit. An acoustic test signal is generated by an external testing device while the hearing aid is worn by a hearing-aid wearer. A digital test input signal is generated by the input transducer on the basis of the acoustic test signal. A sound pressure-dependent test quantity is determined on the basis of the digital test input signal by the evaluation unit. A deviation between the sound pressure-dependent test quantity and a reference quantity stored in the signal processing device is determined by the comparator unit. A pre-amplification by the pre-amplification unit is adjusted on the basis of the determined deviation.

The invention relates to the technical field of microphones, in particular to an online trimmed MEMS microphone. The online trimmed MEMS microphone comprises an acoustic transducer for receiving an external ultrasonic signal and converting the ultrasonic signal into an electric signal; an ASIC (Application Specific Integrated Circuit) chip, coupled to the acoustic transducer, wherein the ASIC chip comprises: an amplifier unit for performing amplification on the electric signal and outputting an amplified signal; a decoding unit, connected to the amplifier unit, and configured to decode the amplified signal to obtain a decoded signal sequence; a matching unit, connected to the decoding unit, and configured to match the decoded signal sequence with a predetermined identification code to obtain a matched signal; a control unit, connected to the matching unit, and configured to generate one or more circuit adjusting parameters under the action of the matched signal.

A method for fitting a hearing device comprises: receiving an audio signal in the hearing device; providing a user interface for inputting at least one modifier value into the fitting device, the modifier value indicating, how a sound property of the audio signal should be modified by the hearing device; processing the audio signal with a sound processor of the hearing device in dependence of the at least one modifier value, thus providing a processed audio signal; outputting the processed audio signal to a user of the hearing device; determining an modifier effectiveness value based on the audio signal, the modifier effectiveness value indicating how much a change of the at least one modifier value results in a perceptible change of the processed audio signal output to the user; and restricting the inputting of the at least modifier value in dependence of the modifier effectiveness value.

At least one exemplary embodiment is directed to a method of generating preferred dynamic range function to process audio reproduced by an earphone device. The function includes processing the audio to improve speech intelligibility. The function is acquired with a self-administered hearing test.

A cord containment adaptor can be adaptively anchored or fixed to or removed from an earphone cord of a set of earphones by hand via an anchor slot of the adaptor. The anchor slot can have a frame or structure that may have multiple earphone cord entrapment chambers and/or an offset or non-linear path leading to an earphone cord entrapment chamber or chambers to help anchor the cord containment adaptor on the cord segment to prevent inadvertent dislodgement of the cord containment adaptor from the earphones. The structure of the anchor slot can be rigid and serves to firmly grip or compress earphone cord segments positioned between gapped-apart opposing sidewalls within the anchor slot. Entrapment chambers of the anchor slot are connected to every other entrapment chamber via cord passageways through which an earphone cord segment can pass. The cord containment adaptor may contain cord containment slots separate from the anchor slot. When a cord containment adaptor is anchored via the anchor slot, earphone cord segments can be gripped into slots in a manner that contains loose cord ends and helps prevent tangling of earphone cords when the earphones are stored or not in use. The adaptor can remain fixed to an earphone cord segment during audio listening by a user and during storage of an earphone set.

A method for estimating an ear geometry of an ear of a user with a hearing device, the hearing device comprising an ear canal microphone, an external microphone, and a receiver, includes: obtaining an external input signal using the external microphone; providing an output signal by the receiver; obtaining an ear canal microphone input signal using the ear canal microphone; and estimating the ear geometry based on the external input signal and the ear canal microphone input signal.

Provided in this disclosure is an acoustic adapter which includes an interior enclosure for substantially surrounding a back of a speaker driver and for defining a predetermined three-dimensional interior volume (3DV1) around the back of the speaker driver to thereby act as a vibration dampener. An exterior enclosure is provided having a configuration that corresponds to a configuration of the interior enclosure and spaced apart from the interior enclosure to define a restricted two-dimensional volume (2DV) outside the three-dimensional interior volume. An aperture is formed in the interior surface of the enclosure for admitting sound into the two-dimensional volume. A foam material is received within the two-dimensional volume (2DV) for at least coating an inner surface of the exterior enclosure, to provide a frictional surface for damping the sound admitted into the two-dimensional volume.
