A hearing device is proposed comprising at least one microphone (), at least one analog-to-digital converter (), a signal processing unit (), a communication unit () for establishing and/or maintaining a communication link to a second hearing device, and a detection unit () for determining a communication link quality. The at least one microphone () is operationally connected to the signal processing unit () via the at least one analog-to-digital converter (), and the communication unit () is operationally connected to the signal processing unit (). By providing said detection unit (), which is operationally connected to the communication unit (), together with a processing scheme selectable in the signal processing unit () in accordance to a determined communication link quality, a binaural hearing system with two hearing devices is for able to adjust its mode in line with the communication link quality, and therewith its capacity.

Binaural hearing device and method to operate the hearing device

Acoustical signals from the acoustical surrounding (U) which impinge upon a reception unitare evaluated and direction of arrival (DOA) of such signals is determined. From signals indicative of such direction of arrival (DOA) a histogram is formed in unit. The behavior of such histogram is classified under different aspects or criteria and dependent on classification results in a classifying unitthe hearing device and thereby especially its signal transfer characteristic from input acoustical signals to output mechanical signals is controlled or adjusted.

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.
