Title
(DE) Zweiseitiges Hörhilfesystem und Verfahren zur Einpassung eines Zweiseitigen Hörhilfesystems
(EN) A bilateral hearing assistance system and a method of fitting a bilateral hearing assistance system
(FR) Système d'assistance auditive bilatérale et procédé d'adaptation d'un tel système
Abstract
(EN)
The application relates to a bilateral hearing assistance system comprising first and second hearing assistance devices, each of the first and second hearing assistance devices being adapted for being located at or in an ear of the user or to be partially or fully implanted in the head at an ear of the user, comprising a processing unit, which in a NORMAL mode of operation is adapted to process an input audio signal based on configurable processing parameters and to provide a processed electric stimulation signal, and comprising an output unit operationally connected to said processing unit in said NORMAL mode of operation and adapted to present an electric stimulation signal input to said user in a form allowing it to be perceived by the user as an auditory signal, the bilateral hearing assistance system further comprising one or more stimulation units for - in a TEST mode of operation of the hearing assistance system - delivering first and second electric TEST stimulation signals to said output units of said first and second hearing assistance devices, respectively. The application further relates to a method of fitting a bilateral hearing assistance system to a particular user. The object of the present application is to provide a measure allowing an improved fitting of bilaterally implanted Cochlear Implant users. The problem is solved in that the bilateral hearing assistance system further comprises an evaluation unit configured to analyze the recorded physiological response of the user and to provide an objective measure of the user's perception of said TEST stimulation signals. This has the advantage of providing an improved speech intelligibility and preservation of spatial cues. The invention may e.g. be used for the fitting of hearing assistance devices comprising cochlear implants.
