碩士 / 國立臺北護理健康大學 / 語言治療與聽力研究所 / 107 / Previous studies about listening effort of population with hearing impairment
demonstrated that under a quiet condition there is no significant difference in speech recognition between listeners with normal and impaired hearing, but under noisy conditions the performance of listeners with impaired hearing is worse than that of listeners with normal hearing. In addition, previous studies about listening effort of population with tinnitus showed that the performance of speech recognition in listeners with tinnitus is worse than that of listeners with normal hearing under both quiet and noisy conditions. This suggests that listeners with tinnitus may have higher listening effort even in a quiet condition, and less attentional resource can be used. Many studies have explored changes of listening effort in speech recognition under different listening conditions for population with hearing impairment, and some studies have started to explore tinnitus effect on speech recognition. Relatively little, however, is known about the relationship between tinnitus and listening effort, and the tinnitus effect on listening effort. Through conducting experiments with different listening conditions, the present study aims (1) to compare the performance of speech recognition, and differences of listening effort under noisy conditions between listeners with tinnitus, and without tinnitus, and (2) to examine the relationship between tinnitus and listening effort.
The present study adopts a cross-sectional and comparative research design (1) to observe the relationship between changes in listening effort, and degree of severity in conscious tinnitus under different listening conditions for experimental and control groups, (2) to determine whether listening effort of subjects with tinnitus is higher than that of subjects without tinnitus, and (3) to explore whether changes in listening effort
of subjects with tinnitus are higher when intensity of noise increases. Total 90 subjects are recruited from the Taipei Veterans General Hospital ear department. The subjects are divided into two groups, control group for subjects without tinnitus and
experimental group for tinnitus, 45 for each. The changes of listening effort in speech recognition tests under both quiet and different noisy conditions will be used to compare the performance between two groups, and the Tinnitus Handicap Index will be used to explore the relationship between listening effort and different degree of severity in tinnitus. Dual task will be adopted to measure listening effort.
The results showed that tinnitus had no significant effect on listen effort at different signal-to-noise ratios, indicating that tinnitus may not be the main influencing factor of the listen effort.
