Embodiment Construction

[0112] Figure 1a-1b The fitting system is shown connected to the hearing aid device HAD in operation, or via a wired communication link ( Figure 1a in "wired link"), or through a wireless communication link ( Figure 1b in "Wireless Link"). The fitting system is preferably configured to initiate the application of appropriate stimulation signals (eg comprising different stimulation intensities) to selected electrodes of the implant of the hearing aid device and to receive the resulting neural responses from the processing unit of the implant. The fitting system is preferably further configured to determine, based on the resulting neural responses, a threshold intensity level T (for the selected electrode) above which the user perceives the stimulus as a sound sensation. Alternatively, the threshold intensity level may be determined in the implant and not necessarily forwarded to the fitting system.

Abstract

The application relates to a hearing assistance device comprising an implanted part adapted for being implanted at a user's ear. The application further relates to a method of operating a hearing assistance device. The object of the present application is to improve identification and processing of recorded nerve response data in an implanted part of a hearing assistance device. The problem is solved in that the implanted part comprises a) A multitude of electrodes adapted for being located in the cochlea in proximity of an auditory nerve of the user; b) Stimulation circuitry electrically coupled to a stimulation electrode during a stimulation time period and configured for applying a stimulation signal to the stimulation electrode; c) Measurement circuitry electrically coupled to a recording electrode during a measurement time period and configured to measure a signal picked up by the recording electrode in response to said stimulation signal and providing a measured signal; d) A control unit configured to control the timing of the application of the stimulation signal in the stimulation time period and to control the measurement time period relative to the stimulation time period; and e) A processing unit configured to record the measured signal in the measurement time period and to identify a response from the auditory nerve based on said measured signal. This has the advantage of reducing the bandwidth requirement of a communication link to an external part during fitting. The invention may e.g. be used for cochlear implant type hearing aids, in particular during the fitting of such hearing aid to a particular user.

Description

technical field [0001] The present invention relates to a hearing aid device comprising an implant, such as a cochlear implant type hearing aid device. In particular, the present invention relates to components that are configured to measure and / or process electrically evoked neural responses (referred to by [Brown et al.; 1990] as "electrically evoked whole nerve action potentials" (EAPs), also known as "electrically evoked auditory potentials" ( EAP)) Hearing aids such as implants of electrically evoked compound potentials (eCAP) or electrically evoked auditory brainstem responses (eABR). [0002] The present application also relates to the use of a hearing device comprising an implant and a method for its operation. [0003] For example, the invention may be used in applications such as cochlear implant hearing aids, especially during fitting of the hearing aid to a particular user. Background technique [0004] Cochlear implant hearing aids have been known for many yea...
