Rate of local cerebral glucose utilization in fetal sheep was measured in conditions of normal laboratory ambient sound (65 to 70 dB sound pressure levels) and broadband noise (105 and 120 dB sound pressure levels) delivered by two earphones situated on the abdominal surface of the ewe. Broadband noise had neither a visible effect on the ewe nor specific effects on the fetal arterial pH, PaO2, PaCO2, and plasma glucose concentration. However, glucose utilization of many cerebral structures was elevated in noise-exposed fetuses.
在正常实验室环境声音（65至70分贝声压级）以及由位于母羊腹部表面的两个耳机传递的宽带噪声（105和120分贝声压级）条件下，测量了胎羊局部脑葡萄糖利用率。宽带噪声对母羊既无明显影响，对胎儿动脉血pH值、动脉血氧分压、动脉血二氧化碳分压及血浆葡萄糖浓度也无特定影响。然而，暴露于噪声环境的胎儿，其许多脑结构的葡萄糖利用率有所提高。
