Auditory Brain stem Responses (ABRs) and behavioural thresholds were studied in 130 neonates born between 25 to 42 weeks of gestational age. ABR thresholds were determined by the weakest stimulus that elicited a recognizable and replicable wave V. Behavioural audiometric thresholds for 1 and 2 kHz pure tones were determined by taking the lowest of threshold for eliciting auro-palpebral reflex. In 130 tested neonates ABR responses were normal in 102 (78.5%) while 28 babies (21.5%) elicited a pathological response. In the normal ABR group mean thresholds values ranged between 24.7-35 dBHL, and it was observed that the thresholds diminished with neonatal maturation. Behavioural audiometry disclosed that 77.5% normal full-term neonates responded to pure tone 1000 Hz, with mean threshold of 92.83 dBHL, while only 59.09% of pre-term neonates responded to pure tone stimuli at 101 dBHL.
对130名胎龄在25至42周之间出生的新生儿进行了听觉脑干反应（ABR）和行为阈值研究。ABR阈值由引出可识别且可重复的V波的最弱刺激确定。1和2kHz纯音的行为听力阈值通过引出耳睑反射的最低阈值来确定。在130名接受测试的新生儿中，102名（78.5%）的ABR反应正常，而28名婴儿（21.5%）出现病理性反应。在正常ABR组中，平均阈值在24.7 - 35 dBHL之间，并且观察到阈值随着新生儿成熟而降低。行为听力测试显示，77.5%的正常足月新生儿对1000Hz纯音有反应，平均阈值为92.83 dBHL，而只有59.09%的早产儿在101 dBHL时对纯音刺激有反应。
