The hearing of 346 babies taken largely from a neonatal intensive care unit has been tested by otoacoustic emissions and brain stem electric response audiometry. A total of 336 (97%) of the babies have been followed up by hearing tests from the age of 8 months. The otoacoustic emission test has been found to be practical with a mean test time of 12.1 minutes compared with 21.0 minutes for brain stem electric response. An otoacoustic emission was recorded bilaterally in 274 (79%) babies. Twenty of the 21 surviving infants who failed brain stem electric response in the neonatal period did not produce an emission. It is concluded that the otoacoustic emission test would make a good first screen to be followed by the brain stem electric response if no otoacoustic emission was present. There is poor agreement between the test results in the neonatal period and those of the follow up period, however, indicating the need for continuous monitoring of those babies failed by brain stem electric response.
对主要来自新生儿重症监护病房的346名婴儿进行了耳声发射和脑干电反应测听检查。共有336名（97%）婴儿从8个月大开始接受听力测试随访。结果发现，耳声发射测试切实可行，平均测试时间为12.1分钟，而脑干电反应测试的平均时间为21.0分钟。274名（79%）婴儿双侧记录到耳声发射。在新生儿期脑干电反应未通过的21名存活婴儿中，有20名未产生耳声发射。得出的结论是，如果没有耳声发射，耳声发射测试可作为良好的初步筛查，随后进行脑干电反应测试。然而，新生儿期和随访期的测试结果一致性较差，这表明需要对脑干电反应未通过的婴儿进行持续监测。
