It was the aim of this study to explore the use of auditory steady-state response (ASSR) to multiple simultaneous stimuli for threshold estimation in young children.
The subjects consisted of 40 children, aged from 6 months to 5 years, with variant degrees of sensorineural hearing loss. Simultaneous tonepips (0.5, 1, 2 and 4 kHz) with an amplitude modulated at different rates from 77 to 103 Hz were presented to both ears by insert phones. All children were tested with ASSR and age-appropriate behavioral tests.
We found that (1) ASSR thresholds were usually higher than behavioral thresholds with a difference of 8-15 dB, (2) the behavioral thresholds were significantly correlated with ASSR thresholds (p = 0.000), and (3) there was a great difference between ASSR thresholds and behavioral thresholds found in a child with auditory neuropathy.
Being objective, frequency specific and well correlated with behavioral thresholds, ASSR to multiple simultaneous stimuli was proven to be a good tool to predict behavioral hearing thresholds.
本研究旨在探讨使用听觉稳态反应（ASSR）对多个同时呈现的刺激进行阈值估计，以用于幼儿听力检测。
研究对象为40名年龄在6个月至5岁之间、患有不同程度感音神经性听力损失的儿童。通过插入式耳机向双耳同时呈现频率为0.5、1、2和4千赫的纯音，并以77至103赫兹的不同速率进行幅度调制。所有儿童均接受ASSR测试和适合其年龄的行为测试。
我们发现（1）ASSR阈值通常高于行为阈值，差值为8至15分贝；（2）行为阈值与ASSR阈值显著相关（p = 0.000）；（3）在一名患有听神经病的儿童中，ASSR阈值与行为阈值存在很大差异。
对多个同时呈现的刺激的ASSR具有客观性、频率特异性，且与行为阈值相关性良好，被证明是预测行为听力阈值的良好工具。
