Embodiment Construction

[0042] The detailed description set forth below in connection with the accompanying drawings serves as a description of a number of different configurations. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. Several aspects of the apparatus and methods are described in terms of a number of different blocks, functional units, modules, elements, steps, processes, etc. (collectively referred to as "elements"). The same elements in different drawings are marked with the same reference signs.

Abstract

A cochlear implant is disclosed in an embodiment. The implant includes a signal level detector configured to determine a total signal level of an incoming acoustic signal and a processing unit configured to determine, in accordance with the determined total signal level, an intermediate knee point for each of a plurality of frequency bands. The implant includes a bandpass filters configured to generate a plurality of band limited audio signals in dependence upon the incoming acoustic signal, each band limited acoustic signal representing an associated audio frequency range relating to at least one electrode of a plurality of an implanted electrode array of the cochlear implant. The implant includes a pulse controller configured to deliver electrical stimulation signals to the plurality of electrodes of the implanted electrode array based on the generated signals and the determined intermediate knee point corresponding to the frequency range.

Description

technical field [0001] The invention relates to a cochlear implant and a method for operating the cochlear implant suitable for electrically stimulating the auditory nerve. In particular, the invention relates to signal processing and stimulation strategies for use with cochlear implants. Background technique [0002] Sensorineural hearing loss is due to the absence or destruction of the hair cells in the cochlea, which are needed to convert sound signals into auditory nerve impulses. People suffering from this type of loss do not benefit from traditional hearing aid systems. This is because their mechanism for converting sound energy into auditory nerve impulses is damaged or substantially damaged. [0003] To overcome sensorineural deafness, a variety of implantable cochlear stimulation (ICS) systems or cochlear prostheses / implants have been developed that seek to bypass the hair cells in the cochlea by presenting electrical stimulation directly to the auditory nerve fib...
