Patent number: 9693155Abstract: Arrangements are described for generating electrode stimulation signals for stimulation contacts in implanted electrode arrays of a bilateral hearing implant system having electrode arrays on both the left- and right-sides. Left-side and right-side audio input signals are processed to generate corresponding left-side and right-side band pass signals, which each represent an associated band of audio frequencies in the audio input signal. Frequency-specific interaural time delays (ITDs) are estimated for the band pass signals, and the estimated ITDs are used to adjust interaural level differences (ILDs) in the band pass signals. The adjusted band pass signals then are used to generate left-side and right-side electrode stimulation signals for the stimulation contacts in the corresponding left-side and right-side electrode arrays.Type: GrantFiled: December 2, 2015Date of Patent: June 27, 2017Assignee: MED-EL Elektromedizinische Geraete GmbHInventors: Dirk Meister, Peter Schleich
