OBJECTIVE
To compare pure-tone audiometry and auditory steady state response (ASSR) to measure hearing loss based on the severity of hearing loss in frequencies.
STUDY DESIGN AND SETTING
A total of 105 subjects (168 ears, 64 male and 41 female) were enrolled in this study. We determined hearing level by measurement of pure-tone audiometry and ASSR on the same day for each subject.
RESULTS
Pure-tone audiometry and ASSR were highly correlated (r=0.96). The relationship is described by the equation PTA=1.05 x mean ASSR - 7.6. When analyzed according to the frequencies, the correlation coefficients were 0.94, 0.95, 0.94, and 0.92 for 0.5, 1, 2, and 4 kHz, respectively.
CONCLUSION
From this study, authors could conclude that pure-tone audiometry and ASSR showed very similar results and indicated that ASSR may be a good alternative method for the measurement of hearing level in infants and children, for whom pure-tone audiometry is not appropriate.
目的
基于频率的听力损失严重程度，比较纯音听力测定法和听觉稳态反应（ASSR）来测量听力损失。
研究设计与设置
本研究共纳入105名受试者（168只耳，男性64名，女性41名）。我们在同一天对每位受试者通过纯音听力测定法和ASSR测量来确定听力水平。
结果
纯音听力测定法和ASSR高度相关（r = 0.96）。这种关系由方程PTA = 1.05×平均ASSR - 7.6描述。按频率分析时，0.5、1、2和4 kHz的相关系数分别为0.94、0.95、0.94和0.92。
结论
从本研究中，作者可以得出结论，纯音听力测定法和ASSR显示出非常相似的结果，并表明ASSR可能是测量婴幼儿听力水平的一种良好替代方法，因为纯音听力测定法不适用于他们。
