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.

Restricting hearing device adjustments based on modifier effectiveness

The present invention pertains to a method for adjusting a hearing device to personal preferences and needs of a user. The proposed method comprises providing initial settings and target settings for signal processing parameters of the hearing device, the user operating the user control element to provide an input for adjusting the current settings so as to meet the personal preferences and needs of the user, adjusting the current settings based on the initial settings and the target settings in dependence of the input to provide adjusted settings for the signal processing parameters. Thereby the user control element is located at the hearing device and/or a hearing device accessory such as a smartphone or tablet. Moreover, the present invention provides a system structured and configured to carry out the proposed method.

Method and system for adjusting a hearing device to personal preferences and needs of a user

A method for adjusting a hearing device comprising: providing a user profile () of the user comprising actual user information () and a fitting history () stored in a database () of a fitting system (), wherein the fitting history comprises fitting information (&#x2033;) of at least one previous fitting session, in which previous fitting session the hearing device () or a different hearing device was adjusted for the user; determining a user experience value () of the user, wherein the user experience value () depends on the actual user information () and the fitting history (); determining sound processing parameters () for the hearing device () based on the user experience value (); and applying the determined sound processing parameters () in the hearing device (), such that the hearing device () is adapted for generating optimized sound signals based on the applied sound processing parameters ().

Automatically determined user experience value for hearing aid fitting

There is provided a method for fitting of a binaural hearing system comprising a first hearing device and a second hearing device to a patient suffering from an asymmetric hearing loss for first time use, wherein the difference in hearing loss between the two ears is at least 5 dB on average in a main frequency range between 500 Hz and 4 kHz.

Fitting method for a binaural hearing system

In order to switch between different hearing programs to adjust to a momentary acoustic surround situation, a method is provided to operate a hearing device as well as a hearing device. Signals, or parameters of a transfer function, are changed smoothly in order to form a smooth transition from a momentary to a desired value. Thereby, the advantage is obtained to eliminate undesired abrupt switching operation when a hearing program switching is necessary.

Method for operating a hearing device as well as a hearing device

A method for individually fitting a hearing instrument to a user, by: starting operation of the hearing instrument; pre-defining a desired target loudness function perceived by the user defined as function of frequency and input sound pressure level at the microphone; measuring for a given measurement parameter set of perceived loudness levels and frequencies or frequency bands the respective transducer input audio signal level to be applied to the transducer input to achieve the respective perceived loudness level at the respective frequency or frequency band, said measurement parameter set having at least a low, intermediate and high loudness levels, and said intermediate loudness level being measured for a larger number of frequencies or frequency bands and with a finer frequency resolution than said low and high loudness levels; calculating an individual gain function to be implemented in the audio signal processing unit to achieve the pre-defined target loudness function by taking into account the measured transducer input audio signal levels; and operating the hearing instrument with the individual gain function.
