['To seek a convenient and effective method through subjective psychophysical measurements and CAP/SIR assessment. To compare the discrimination of rehabilitation between post-lingual and pre-lingual deafened patients.', 'Thirty-one post-lingual cochlear implantees and 59 pre-lingual cochlear implantees, the warble tone and CAP/SIR were assessed. The discrimination of threshold levels, comfortable levels and dynamic range between post-lingual and pre-lingual deafened patients in same electrodes were compared.', 'There was no statistic difference in warble tone, T-levels, C-levels and dynamic range in same electrodes implant after 6 months implant (P>0.05). The score of CAP and SIR in post-lingual deafened patients were more prominent.'] Do [ Study of aural rehabilitation in post-lingual deafened patients with multi-channel cochlear implant ]?
