A method for fitting a hearing device to the needs and preferences of a user of the hearing device is disclosed. In a first step of the disclosed method, a first range for a parameter setting of a first parameter is determined based on a first audiological test performed with the user. In a second step of the disclosed method, the first parameter is adjusted to a first final parameter setting within the first range and/or a second parameter of the hearing device is adjusted to a second final parameter setting based on a second audiological test performed with the user. The second parameter is functionally related to the first parameter such that the first parameter is expressible as a function of the second parameter, and the adjusting is performed such that the first parameter setting remains within the first range. Additionally, corresponding fitting apparatuses and computer-readable media are disclosed.

Method and apparatus for fitting a hearing device

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.

An audio signal processing unit establishes audio signal processing of the device according to individual needs and/or purpose of the device. At least one electrical/mechanical output converter is provided. A filter arrangement with adjustable high-pass characteristic has a control input for the characteristic.

Method for manufacturing acoustical devices and for reducing especially wind disturbances

A hearing device has an adjustable transfer function comprising M&#x2267;1 sub-functions (M is an integer). A method for operating the hearing device includes deriving input audio signals from a current acoustic environment. For each of the M sub-functions, derive, based on the input audio signals and for each class of N&#x2267;2 classes that describe a predetermined acoustic environment, a class similarity factor indicative of the similarity of the current acoustic environment with the predetermined acoustic environment described by the respective class (N is an integer). Derive from N predetermined base parameter sets assigned to the respective sub-function and in dependence of the class similarity factors, an activity parameter set for the respective sub-function. Each of the N base parameter sets assigned to the respective sub-function is assigned to a different class of the N classes. Adjust the respective sub-function by means of the activity parameter set.

A method to adjust parameters of a transfer function of a hearing device is disclosed, the method comprising the steps of extracting features of an input signal fed to the hearing device, classifying the extracted features into one of several possible classes, selecting a class corresponding to a best estimate of a momentary acoustic scene, adjusting at least some of the parameters of the transfer function in accordance with the selected class representing the best estimated momentary acoustic scene, and training the hearing device to improve classification of the extracted feature or the best estimate of the momentary acoustic scene, respectively, during regular operation of the hearing device. As a result, the hearing device does not only improve its behavior when new data is presented lying outside of known training data, but the hearing device is also better and faster adapted to most common acoustic scenes, with which the hearing device user is confronted.
