We evaluated conventional ASSR (Bio-logic MASTER II) and NB CE-Chirp ASSR thresholds as objective hearing measures in both normal and hearing loss subjects.
Patients with sensorineural hearing loss and volunteer normal hearing subjects were enrolled. Pure tone thresholds at 0.5, 1, 2 and 4 kHz were compared with the corresponding thresholds measured using Bio-logic MASTER II and the Eclipse ASSR systems. The threshold differences and correlation with pure tone were measured and reliability was evaluated with Cronbach's α. In part I of the study, all subjects were included, in part II of the study, only mild hearing loss and normal hearing subjects were included.
In part I, NB CE-Chirp ASSR revealed a significantly smaller difference in threshold than conventional ASSR, a better correlation and better reliability. However, lower frequencies of NB CE-Chirp tended to be less reliable than higher frequencies. In part II, NB CE-Chirp revealed smaller threshold differences than conventional ASSR. Both correlation scores and reliability values were generally lower in the part II results.
NB CE-Chirp ASSR generally revealed more favorable outcomes. However, its reliability was reduced at lower frequencies and in patients with milder hearing loss.
我们评估了传统听性稳态反应（Bio-logic MASTER II）和窄带CE-线性调频脉冲听性稳态反应阈值，将其作为正常受试者和听力损失受试者的客观听力检测指标。
纳入感音神经性听力损失患者和听力正常的志愿者。将0.5、1、2和4kHz的纯音阈值与使用Bio-logic MASTER II和Eclipse听性稳态反应系统测得的相应阈值进行比较。测量阈值差异以及与纯音的相关性，并使用克朗巴赫α系数评估可靠性。在研究的第一部分，纳入所有受试者；在研究的第二部分，仅纳入轻度听力损失和听力正常的受试者。
在第一部分中，窄带CE-线性调频脉冲听性稳态反应显示出比传统听性稳态反应更小的阈值差异、更好的相关性和更高的可靠性。然而，窄带CE-线性调频脉冲较低频率的可靠性往往低于较高频率。在第二部分中，窄带CE-线性调频脉冲显示出比传统听性稳态反应更小的阈值差异。第二部分结果中的相关性得分和可靠性值总体上较低。
窄带CE-线性调频脉冲听性稳态反应总体上显示出更有利的结果。然而，其在较低频率以及听力损失较轻的患者中可靠性降低。
