Abstract

BACKGROUND AND OBJECTIVES
Hearing in Noise Test (HINT) sentences and Central Institute for the Deaf (CID) sentences are tools that are used for assessing speech cognition. The Korean versions of HINT and CID, KHINT and KCID, have been made and used for the selection of cochlear implant candidates. In this study, we analyzed the compatibility of sentences of KCID and KHINT as testing material for assessing speech performance.
MATERIALS AND METHODS
A total of 36 patients selected for the study were divided into 2 groups. Group A, whose mean age was 49.9 years, was composed of 18 patients with hearing aid (range, 24 to 68 years); Group B, whose mean age was 23.5 years, was composed of 18 patients with cochlear implant (range, 10 to 63 years). Open set recognition scores of 2 sentences were compared in each group, by randomly selecting one list each of the KCID and KHINT sentences. Sentences were stimulated using recorded voice and live voice for Group A and B, respectively.
RESULTS
There were no statistically significant differences between mean scores of KCID and KHINT sentences in each group (p=0.289, 0.208), respectively. However, there were statistically significant linear correlations between KCID and KHINT sentences in each group and total group (R2=0.961, 0.945, 0.923, respectively; p<0.01, <0.01, <0.01, respectively).
CONCLUSION
KCID sentences can be used as a speech performance test material and might serve as a compatible test material for selection of the cochlear implant candidacy.
