Abstract
En 中文
This study investigated the extent to which 9 months of listening with bilateral cochlear implants (CIs) improves the ability of children to hear speech in noise and to localize sounds. Three children ages 8-12 who received sequential bilateral CIs, 3-8 years apart, participated in a series of binaural tasks at 3 and 9 months after activation of the second CI. Each child participated in a battery of tests under unilateral and bilateral conditions. Results suggest that speech intelligibility in noise improves with added bilateral experience, but that speech intelligibility in quiet does not. In addition, the improvement was seen primarily for the two younger children, who had received the second CI at the age of 8, but not for the older child whose second CI was received at the age of 12. None of the children were able to localize sounds well at 3 or 9 months after receiving the second CI. Further research is necessary to establish the importance of age of implantation and duration of bilateral experience necessary in order for maximal performance to be achieved. (c) 2004 Elsevier B.V.
