['To evaluate sound localization ability in patients with unilateral cochlear implant, who do not wear a hearing aid on the contralateral ear, and to try to improve this ability by training.', 'Tertiary academic referral center.', 'In the initial test, patients were exposed to sound stimuli from different directions and were asked to localize them. Following a training period the patients were re-evaluated by the same test. For each test, the percentage of correct answers and the final test score were calculated.', 'In the initial test, the mean score of the study group of four cochlear implant users was 42.8 (out of a maximal score of 100), the mean rate of correct responses was 27.5%. Following a training period (6.5 sessions on the average), on the final test the mean score of the group was 74.3, while the mean rate of correct responses was 66.5%.'] Do sound localization in patients with cochlear implant -- preliminary results?
