1. A system comprising:
a first device for neural stimulation of a cochlea of a patient's ipsilateral ear; a second hearing stimulation device selected from the group consisting of a device for neural stimulation of the cochlea of the patient's contralateral ear, a device for acoustic stimulation of the patient's ipsilateral ear, and a device for acoustic stimulation of the patient's contralateral ear, and comprising means for stimulation of the respective ear; and a fitting device for adjusting at least one of the first stimulation device and the second stimulation device according to a response of the patient to combined stimulation by the first stimulation device and the second stimulation device; the first stimulation device comprising
a sound processor for generating a neural stimulation signal from an input audio signal; anda cochlear implant stimulation arrangement comprising a plurality of stimulation channels for stimulating the ipsilateral cochlea at various stimulation sites according to a neural stimulation signal, with each stimulation channel being attributed to a certain one of the stimulation sites; the fitting device comprising
a unit cooperating with the first stimulation device and with the second stimulation device in order to generate, in a synchronized manner, a probe neural stimulation signal to be supplied to the cochlear implant stimulation arrangement and a second probe stimulation signal be supplied to the stimulation means of the second stimulation device, with the probe neural stimulation signal and the second stimulation signal being adapted to be recognized by the patient as carrying a target speech information in case that the patient is able to correctly fuse the stimuli resulting from the probe neural stimulation signal and the second stimulation signal in the auditory cortex, with the target speech information being divided onto the probe neural stimulation signal and the second stimulation signal, and with the probe neural stimulation signal and the second stimulation signal not carrying said target speech information when perceived separately by the patient,a unit for recording the perceptual behavioral response of the patient to the synchronized neural stimulation of the user's hearing with the probe neural stimulation signal and the second stimulation signal, anda unit for programming the first stimulation device and/or the second stimulation device according to the recorded perceptual response. |
