摘要

The purpose of the study was to investigate the effect of tinnitus upon speech recognition in normal hearing tinnitus subjects. Seventeen normal hearing subjects with tinnitus which lasting more than 2 months as the tinnitus group, and nineteen normal hearing subjects without tinnitus as the control group. The speech tasks and the conditions administered to the two groups included MPB (Mandarin Phonetic Balance test) test in quiet, HP (high-predictability) and LP (low-predictability) sentences of Mandarin SPIN (MSPIN) test in +6dB and 0dB signal to noise ratio (S/N). Our result showed no significant difference in the Mandarin PB scores. For HP sentences, no significant difference was found in +6 dB S/N condition and a significant difference in 0dB S/N (p＜.001) condition. For LP sentences, significant differences were found in both +6 dB (p＜.05) and 0 dB S/ N (p＜.001) conditions. Our result suggested that under easier listening condition and the context cues were provided, the speech perception of tinnitus group was as good as that of control group. However in noisy environment, in spite of context cues provided, tinnitus itself does affect speech understanding.
