将６４名聋哑儿童分为清醒组（Ａ组）、睡眠组（Ｂ组）和自身对照组（Ｃ组），用０．５ｋＨｚ及１ｋＨｚ短音刺激，测得４０Ｈｚ听觉相关电位（ＡＥＲＰ）反应阈，并与听性脑干反应阈比较。发现：用１１５ｄＢｐｅＳＰＬ短声刺激未能引出ＡＢＲ的７３耳中，用０．５ｋＨｚ短音刺激引出４０ＨｚＡＥＲＰ者５５耳，用１ｋＨｚ短音刺激引出４０ＨｚＡＥＲＰ者５５耳。表明４０ＨｚＡＥＲＰ对测试聋哑儿童低频听阈较为有效。比较Ａ、Ｂ两组的４０ＨｚＡＥＲＰ诱出率，无显著差异（Ｐ＞０．０５）。Ｃ组的清醒与睡眠状态４０ＨｚＡＥＲＰ诱出率自身比较：刺激音为０．５ｋＨｚ或１ｋＨｚ短音时，睡眠组４０ＨｚＡＥＲＰ诱出率明显高于清醒组（Ｐ＜０．０００１）。表明睡眠对测试儿童４０ＨｚＡＥＲＰ反应阈无明显不良影响。当聋儿不合作时，用药物催眠后，由于信噪比改善，４ｎＨｚＡＥＲＰ的诱出率明显提高，这为４０ＨｚＡＥＲＰ能在聋儿测听中广泛应用创造了条件。
Sixty deaf children were divided into awake group (group A), sleep group (group B) and self-control group (group C). The 40 Hz auditory related potentials (AERP) were measured with 0.5 kHz and 1 kHz short tone Threshold, and compared with auditory brainstem response threshold. Found: 115dBpeSPL short stimulation of the ABR can not lead to 73 ears, with 0.5kHz short tone stimulated 40HzAERP led to 55 ears, with 1kHz short tone stimulated 40HzAERP 55 ears. This indicates that 40 Hz AERP is more effective in testing low-frequency thresholds for hearing-impaired children. There was no significant difference in the 40-Hz AERP-induced rates between groups A and B (P> 0.05). Compared with the 40 Hz AERP inducement rate in awake and sleep states of group C, the 40 Hz AERP inducing rate in sleep group was significantly higher than that in awake group (P <0.0001). Indicating that sleep had no significant adverse effect on the 40 Hz AERP response threshold of children tested. When deaf children do not cooperate, with the drug hypnosis, due to the improvement of signal to noise ratio, the induction rate of 4nHz AERP significantly increased, which is 40HzAERP can be widely used in deaf children’s hearing to create the conditions.
