Middle latency (10-50 ms) responses (MLR) evoked by tone-pips (1,000 Hz 500 Hz) and early (0-10 ms) auditory evoked potentials (EAEP) evoked by chicks were recorded on 68 newborn babies (premature or at term), infants and children, some with central nervous system or psychiatric disorders, who had normal or impaired hearing. MLR were obtained either during sleep, chloral-hydrate sedation or ketamine anesthesia. Thresholds estimated from MLR and EAEP were compared to those from subsequent psychoacoustic pure tone testing. We confirm that MLR provide good threshold estimates for hearing in the low frequency range, whereas click evoked EAEP are good threshold indicators only for high frequencies.
在68名听力正常或受损的新生儿（早产或足月）、婴儿和儿童中记录了由短音（1000赫兹、500赫兹）诱发的中潜伏期（10 - 50毫秒）反应（MLR）以及由短声诱发的早期（0 - 10毫秒）听觉诱发电位（EAEP），其中一些儿童患有中枢神经系统或精神疾病。MLR是在睡眠、水合氯醛镇静或氯胺酮麻醉期间获得的。将从MLR和EAEP估计的阈值与随后的心理声学纯音测试的阈值进行比较。我们证实，MLR为低频范围内的听力提供了良好的阈值估计，而短声诱发的EAEP仅对高频是良好的阈值指标。
