碩士 / 國立臺北護理健康大學 / 聽語障礙科學研究所 / 102 / Tinnitus can be described as the perception of sound in the absence of external acoustic stimulation. The size of the tinnitus population in the United States is nearly 30 million or about 10% of their entire population and the incidence of tinnitus are as high as 26.7% for people ages 65-84 years. Within that population, 75 to 80 percent of patients with hearing loss may experience tinnitus symptoms. In this study, patients with hearing loss and tinnitus are evaluated to distinguish factors associated with the effectiveness of hearing aid use.
Thirty four subjects were recruited between March and November 2013, at Mackay Memorial Hospital ENT outpatient department. Pure tone thresholds were assessed at 500, 1000, 2000 and 4000 Hz. Subjects with pure tone loss between 40dBHL with less 91dBHL were included in the study. These subjects experienced tinnitus symptoms with the use of hearing aids for at least three months.
The study utilized questionnaires to survey the factors associated with the effectiveness of hearing aids use by subjects with hearing loss and tinnitus. Subjects received both Tinnitus Handicap Inventory and the Chinese version of State-Trait Anxiety Index. The study also used the SPSS 19 statistical software packages for descriptive statistics. Statistical analysis methods used include Chi-square test, Pearson correlation coefficient, Spearman Rank Correlation and simple linear regression analysis.
The Pearson chi-square test was used to determine correlation of the lengths of time in which the hearing aids were in use by subjects with tinnitus symptoms. The significance value of .027 and Spearman Rank Correlation of .591(p=.000) were observed. The moderately positive correlation and the linear regression analysis showed that the average daily time of use for tinnitus hearing aids improve the symptoms have an explanatory power of 27.2%(p=.002), an explanatory power of statistical significance; THI and STAI-T Pearson correlation coefficient analysis of .633(p=.000) were also observed, reaching a moderate positive correlation. STAI-T predict THI with 43.9% of the explanatory power, F=25.065, p=.000, the explanatory power of statistical significance.
The results of this study suggested that among patients with hearing loss, with the use of hearing aids, about 65% may exhibit improvements of tinnitus. In addition, it was observed that a prolonged period of hearing aid use produces higher improvements. Through the use of STIA-T, patient anxiety levels are assessed to predict the validity extent of THI. It was found that the patients with higher STAI-T scores also consumed higher THI scores.
