Method: HQ and Beck Anxiety Inventory (BAI) were administered to a total of 529 participants (320 female, 209 male), aged 18 to 73 (mean age: 29.76±10.59) years who were randomly se-lected from the general population. For the evaluation of the data, confirmatory and exploratory factor analysis, correlation analysis, descriptive statistics, t-test, analysis of variance, and Sidak correction test were used. Results: In the reliability analysis, the Cronbach’s alpha (aC) internal consistency coefficient was found to be 0.81. Factor analysis revealed three subdimensions (attentional, social, and emotio-nal). The total variance of these three subdimensions were 63%, and the internal consistency of the subdimensions was also high (αC >0.70). Confirmatory factor analysis and structural equa-tion modeling results indicated that three-factor solutions with 14 items met the criteria for the adequacy of fit among the Turkish patients. The mean score for hyperacusis was estimated as 15.69±6.63 points.There was a positive, weak, but significant association between hyperacusis and anxiety (r=0.357, p=0.01, p<0.05). The patients who were exposed to noise were found to have higher levels of hyperacusis, compared to those who were not (t=6.78, p=0.01, p<0.05). The patients who had decreased noise tolerance over time were found to be higher hyperacusis levels than those without (t=4.83, p=0.01, p<0.05). Conclusion: Based on these measurements, 14 questions and three-factor solutions were found to be a valid and reliable tool.
