Clinical study of continuous interleaved sampler and simultaneous analog stimulation in cochlear implant patients

ABSTRACT

This study included 15 consequently implanted, postlingually deafened adults. Fifteen patients were initially programmed and tested with both CIS and SAS. All patients were fitted by clarion cochlear implant and stimulated by enhanced bipolar configuration simultaneous analog stimulation [SAS] strategy and continuous interleaved sampler [CIS] strategy. The CIS strategy offered an output-sampling rate of 6.500 pulses per second. The SAS strategy offered a currently implements with an overall rate 104.000 samples per second. Post implant tests included monosyllabic words and sentences in quiet and in noise using digitally recorded speech test. It was concluded that the availability of both ASA and CIS speech processing strategies offers a greater opportunity for achieving improved patient performance and increases the overall benefit
