Abstract：
BACKGROUND: This study examined the relationship between behavioural thresholds as measured by pure tone audiometry and electrophysiological thresholds measured by the Auditory Steady-State Response (ASSR) in children with normal hearing and sensorineural hearing loss.
METHODS: After being assessed, 45 children of both sexes, ranging in age from 5 to 15, were split into four groups: 10 with moderate to moderately severe sensorineural hearing loss (G2M); 10 with steeply sloping sensorineural hearing loss (G2D); 10 with profound and severe sensorineural hearing loss (G2S); and 15 with normal hearing (G1). ASSR, tympanometry, acoustic reflex testing, pure tone audiometry, and speech audiometry (SRT and SDT) were performed.
RESULTS: The electrophysiological maximum in the group with normal hearing thresholds varied from 19 to 27 dB NA. The correlation in the group with moderate to moderately severe hearing loss was 0.42-0.74. The correlation in the steeply sloping hearing loss group was 0.68-0.94. The correlation in the group of people with profound and severe hearing loss was 0.59-0.86. The normal hearing group\'s mean differences in ASSR threshold and audiometric threshold ranged from -0.3 to 12 dB, in the moderate and moderately severe hearing loss group from -9 to 2 dB, in the steeply sloping hearing loss group from 1.4 to 7.5 dB, and in the severe and profound hearing loss group from -0.40 to 8.5 dB.
CONCLUSIONS: As expected, there was no strong relationship between behavioural and electrophysiological thresholds in the group with normal hearing. But in children with hearing loss, there was a strong correlation between electrophysiological and behavioural thresholds; this relationship was especially evident in children with severe and profound hearing loss and those with steeply sloping hearing loss.

摘要：
背景：这项研究调查了正常听力和感音神经性听力损失儿童的纯音测听法测量的行为阈值与听觉稳态反应（ASSR）测量的电生理阈值之间的关系。
方法：经过评估，45名男女儿童，年龄在5至15岁之间，分为四组：10例中度至中度感音神经性听力损失（G2M）；10例陡峭倾斜的感音神经性听力损失（G2D）；10例深度和重度感音神经性听力损失（G2S）；15例听力正常（G1）。ASSR,鼓室测压,声反射测试,纯音测听法,和言语测听（SRT和SDT）。
结果：具有正常听力阈值的组中的电生理最大值在19至27dBNA之间变化。该组中重度听力损失的相关性为0.42-0.74。陡峭倾斜的听力损失组的相关性为0.68-0.94。重度和重度听力损失人群的相关性为0.59-0.86。正常听力组ASSR阈值和测听阈值的平均差异范围为-0.3至12dB，在-9至2dB的中度和中度重度听力损失组中，在1.4至7.5dB的陡峭倾斜听力损失组中，严重和深度听力损失组从-0.40分贝到8.5分贝。
结论：如预期的那样，听力正常组的行为阈值和电生理阈值之间没有很强的相关性.但是在有听力损失的儿童中，电生理阈值和行为阈值之间有很强的相关性;这种关系在重度和重度听力损失的儿童和听力急剧下降的儿童中尤其明显.
