To evaluate the adverse effects of noise on hearing. Thirty-two infants that had been admitted to neonatal intensive care unit (NICU) and 25 healthy controls were included in this study. Noise levels were recorded continously during the hospitalization period. All healthy controls passed the hearing screening tests before discharge and on the sixth-month follow up. Hospitalized infants had lower "Distortion Product Auto Acoustic Emission Signal Noise Ratio" (DPOAE SNR) amplitudes (dB) at five frequencies (1001, 1501, 3003, 4004, 6006 Hz in both ears). DPOAE fail rates at 1001 Hz and 1501 Hz were higher than in hospitalized infants (81.8% and 50.0% vs 20.0% and 4.0%). Infants who failed the test at 1001 and 1501 Hz were exposed to noise above the recommended maximum level for longer periods of time. Hearing tests performed at sixth-months of life were adversely affected in NICU graduates.
为了评估噪声对听力的不良影响。本研究纳入了 32 名入住新生儿重症监护病房（NICU）的婴儿和 25 名健康对照。在住院期间连续记录噪声水平。所有健康对照者在出院前和 6 个月随访时均通过听力筛查测试。住院婴儿双耳五个频率（1001、1501、3003、4004、6006Hz）的“畸变产物自动声发射信号噪声比”（DPOAE SNR）幅度（dB）较低。1001Hz 和 1501Hz 的 DPOAE 失败率高于住院婴儿（81.8%和 50.0%比 20.0%和 4.0%）。在 1001Hz 和 1501Hz 测试失败的婴儿接触噪声的时间超过了建议的最大水平。NICU 毕业生在 6 个月大时进行的听力测试受到不利影响。
