To examine the effect of noise exposure during pregnancy on infant birth weight, a well-characterized cohort of 200 pregnant women in the first trimester participating in prenatal care clinics was followed throughout gestation (in Taiwan, 1991). Individual 24-hour noise exposure of all women was prospectively measured, and information regarding possible noise exposure from traffic and occupation was also obtained. Noise exposure during pregnancy was correlated with the birth weights of the women's babies. No association between personal noise exposure measured in decibels (less than 85 dBALeq during pregnancy) and birth weight was found. Possible occupational noise exposure (indicated by working in a manual job), traffic noise exposure (indicated by distance between the home and main streets), and a history of listening to amplified music and using personal listening devices during pregnancy also showed no effect on infant birth weight. Maternal weight, maternal weight gained during pregnancy, gestational age, and infant's sex were the four factors that correlated significantly with birth weight. The noise exposure experienced by women during pregnancy may not be great enough to affect their infants' birth weight.
为研究孕期噪声暴露对婴儿出生体重的影响，1991年在台湾，对200名在孕早期参加产前保健诊所的孕妇组成的特征明确的队列进行了全程跟踪。前瞻性地测量了所有女性的24小时噪声暴露情况，并获取了有关交通和职业可能产生的噪声暴露的信息。孕期噪声暴露与女性所生孩子的出生体重相关。未发现以分贝为单位测量的个人噪声暴露（孕期小于85 dBALeq）与出生体重之间存在关联。可能的职业噪声暴露（以从事体力工作表示）、交通噪声暴露（以家与主要街道之间的距离表示）以及孕期听放大音乐和使用个人听力设备的历史，对婴儿出生体重也均无影响。母亲体重、孕期增加的体重、孕周和婴儿性别是与出生体重显著相关的四个因素。女性孕期经历的噪声暴露可能不足以影响其婴儿的出生体重。
