目的：为探讨睡眠状态下听觉稳态诱发电位（SSEP）与行为听阈的关系，设计：选择60名听阈正常至极高的成年人和儿童，根据相应的听力图进行测试。在倍频程频率250-4000 Hz下测定行为听力图。然后将这些行为阈值与成人自然睡眠期间获得的SSEP阈值进行比较，或者与儿童自然或镇静睡眠期间获得的SSEP阈值进行比较。这种关系的强度随着频率的增加和损失程度的增加而增加。在这些数据的基础上，确定了从SSEP水平预测行为阈值。结果表明：SSEP技术在250-4000 Hz频率范围内可用于预测成人和儿童的行为阈值，其误差标准差随频率的增加和丧失程度的增加而减小，且无明显的年龄效应。
Objective: To examine the relationship between auditory steady-state evoked potentials (SSEPs) and behavioral thresholds in sleeping subjects.Design: 60 adults and children with hearing thresholds ranging from normal to profound were selected on the basis of appropriate audiograms. Behavioral audiograms were determined at the octave frequencies 250-4000 Hz. These behavioral thresholds were then compared with the SSEP thresholds obtained during natural sleep for adults, or natural or sedated sleep for children.Results: A strong relationship between behavioral and SSEP thresholds was observed. The strength of the relationship increased with increasing frequency and increasing degree of the loss. On the basis of these data, the prediction of behavioral thresholds from SSEP levels was determined. It was found that the standard deviation of the error in this prediction decreased with increasing frequency and increasing degree of the loss, There was no significant age effect in the results obtained at any of the frequencies.Conclusion: The results suggest that the SSEP technique can be used as a predictor of behavioral thresholds in adults and children at the frequencies 250-4000 Hz.
