Abstract
A hearing assistance device comprises an implantable part for electrically stimulating an auditory nerve of a user. The implanted part comprises a) a current source generator; and b) an electrode array configured to be located inside one of the cochlear scala or adjacent to the auditory nerve. The hearing assistance device is configured to produce a time-varying waveform delivered by the current source generator, the time-varying waveform comprising a positively sloping positive pulse. This has the advantages of providing a smaller spatial spread of neurons being discharged by electric stimuli from a given electrode. The invention may e.g. be used in cochlear implant hearing assistance devices.
