Abstract: According to the invention, in a hearing instrument it is once or repeatedly checked whether a second hearing instrument is present and active. If a second hearing instrument is active on the contralateral side, a first gain (corresponding to the gain for binaural fitting) is applied. If, however, no further hearing instrument is found to be active, a second—increased—gain is applied. The second gain may simply correspond to the first gain increased by a certain dB value. It may as an alternative be a specifically adapted gain characteristic of a monaural fitting for the user.

Abstract: 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.

Abstract: In order to switch between different hearing programs to adjust to a momentary acoustic scene, a method for adjusting a hearing device, in which one of several possible hearing programs can be selected in order to adjust to a momentary acoustic scene, the method comprising the steps of detecting a desired hearing program change, changing parameters (b1, . . . , bm) of a transfer function provided between a microphone (M1) and a receiver of the hearing device in order to adapt it to the detected hearing program change, adjusting the parameters (b1, . . . , bm) to be changed from a momentary value to a desired value in such a manner that a smooth transition is perceived by the hearing device user while changing from a momentary hearing program to the desired hearing program, whereas each of the smooth transition is individually adjustable.
