Abstract

In 2019, the Japanese Society of Otolaryngology created the iCI2004, the “Word Tone Listening Assessment Test for Artificial Hearing Devices”. This test consisted of a monosyllable test and a word test. The word test is expected to have a better response rate than the monosyllable test because it provides a logical complement to the word test. In this study, the correct response rates for the monosyllable and word tests were compared in cochlear implant cases. The results showed that the adult group had an average of 52.1% for the monosyllable test and 72.8% for the word test, while the pediatric group had an average of 57.2% for the monosyllable test and 80.1% for the word test, with a significant difference between groups. The difference in performance between the two tests was approximately 20%. The percentage of correct responses for the monosyllable and word tests was not significantly different between the adult, child, and word test only groups (p > 0.05). In addition, the test could be administered at younger ages with a word test rather than a monosyllable test. If the subject is younger, there may be situations in which the monosyllable test is difficult to perform. Even in such cases, there are cases where word tests can be performed. Based on the above, we expect that the word test will be actively used.
