对75例新生儿重症监护病房患者进行了高于正常成人听阈40 dB和70 dB的听性脑干反应筛查试验。波V的存在，通过的标准，是密切相关的后概念年龄：它出现在70分贝在50%的婴儿在32周的PCA和40分贝在50%的婴儿在40周的PCA。44名婴儿在NICU出院前的最后一次测试失败（15名在70 dB，29名在40 dB），但大多数婴儿在PCA不到40周时出院。ABR试验失败与脑室内出血、肺透明膜病、围产期窒息、高胆红素血症或氨基糖苷类药物治疗之间无显著相关性。在36名存活的“失败”婴儿中，有23名获得了随访信息（8名死亡）。这包括10名患者的确定性听力测试和13名患者的历史信息支持正常的听觉功能。确诊1例重度听力损失。因此，大多数失败的ABR屏幕显然是由于不成熟。这些数据引起了对ABR筛查在NICU中的有效性的怀疑。
Seventy-five neonatal intensive care unit patients were given auditory brainstem response screening tests at 40 db and 70 db above the normal adult hearing threshold. The presence of wave V, the criterion for pass, was strongly related to postconceptual age: It appeared at 70 db in 50% of the infants tested at 32 weeks' PCA and at 40 db in 50% of the infants tested at 40 weeks' PCA. Forty-four infants failed the last test before NICU discharge (15 at 70 db and 29 at 40 db), but most infants were discharged at a PCA of less than 40 weeks. No significant correlation appeared between ABR test failure and intraventricular hemorrhage, hyaline membrane disease, perinatal asphyxia, hyperbilirubinemia, or aminoglycoside therapy. Follow-up information was obtained in 23 of the 36 “failing” infants who survived (8 died). This consisted of definitive hearing tests in ten patients and historical information supporting normal auditory function in 13 patients. One case of severe hearing loss was confirmed. Thus, most failures of the ABR screen apparently resulted from immaturity. These data raise doubts regarding the effectiveness of ABR screening in the NICU.
