Abstract

A series of experiments was run to assess bilateral cochlear implant users' ability to fuse information presented dichotically. Two different methods of splitting the spectral information were investigated. In the first method, the odd-index channels were presented to one ear and the even-index channels to the other ear. In the second method, the lower frequency channels were presented to one ear and the high-frequency channels to the other ear. Results from word recognition tests indicated that in quiet, the bilateral implant users were able to fuse the information presented dichotically as accurately as when presented diotically. In contrast, subjects were not able to fuse the information presented dichotically in noise as accurately as when presented diotically.
