Preterm babies and newborns with certain health conditions, such as low birth weight and breathing difficulties, often need incubators to keep them warm and safe from infections.
患有某些健康状况的早产儿和新生儿，如低出生体重和呼吸困难，通常需要保温箱来保持温暖和安全，以免感染。
However, a new study has revealed the sounds inside these life-saving devices may damage the hearing of premature babies.
然而，一项新的研究表明，这些救生设备内部的声音，可能会损害早产儿的听力。
Incubators are self-contained units that are capable of providing a safe, temperature-controlled environment for babies that needs NICU care.
保温箱是独立的单元，能够为需要NICU护理的婴儿提供安全、温度可控的环境。
Apart from providing a safe and warm bed for the baby to sleep in, incubators are designed to create an ideal environment for the infants to thrive by providing them with the perfect amount of oxygen, humidity, and light.
除了为婴儿提供一个安全温暖的床外，保温箱还旨在通过为婴儿提供完美的氧气，湿度和光线，为婴儿创造理想的成长环境。
Here are some reasons a baby would need an incubator:
以下是婴儿需要保温箱的一些原因：
Preterm birth
早产
Infection
感染
Breathing Issues
呼吸问题
Jaundice
黄疸
Traumatic birth
创伤性分娩
Low birth weight
出生体重过低
Post-surgery recovery
术后恢复
Now, researchers have found that by the age of three, nearly 50% of preterm infants show deficits in language acquisition. Scientists believe that the NICU noise can be a possible contributor to the increased risk of hearing impairment, which could lead to delays in language acquisition.
现在，研究人员发现，近50%的早产儿在三岁时表现出语言习得方面的缺陷。科学家们认为，新生儿重症监护室的噪音可能会增加听力障碍的风险，从而导致语言习得的延迟。
The study published in Frontiers in Pediatrics evaluated the sound characteristics inside a NICU incubator based on 11 environmental noises and 12 incubator handling noises.
这项发表在《儿科前沿》（Frontiers in Pediatrics）上的研究，基于11种环境噪声和12种保温箱处理噪声，评估了新生儿重症监护室保温箱内的声音特征。
The environmental noises include starting and switching off the incubator engine, normal conversation, laughter, telephone sounds, infusion pump alarm sounds, monitor alarm, and blood pressure measurement.
环境噪声包括开机、关机、正常对话、笑声、电话声音、输液泵报警声、监控器报警声、血压测量等。
Meanwhile, noises in the incubator handling included sounds of water flap, water pouring into the incubator, sounds of opening and closing incubator doors and hatches, taking and putting a stethoscope on the incubator, and noises from the suctioning tube.
与此同时，保温箱操作中的噪声包括水瓣声、水注入保温箱的声音、打开和关闭保温箱门和舱口的声音、在保温箱上拿听诊器和放听诊器的声音、吸管的声音。
The noise involved inside the incubator was not perceived as loud by those who were working with the incubator. Although the incubator dampens most sounds, some sounds resonate inside the incubator, the researchers said.
在孵化器内工作的人并不认为孵化器内的噪音很大。研究人员说，尽管保温箱能抑制大多数声音，但有些声音在保温箱内会产生共鸣。
Although the findings of the study cannot be generalized, as the sounds inside incubators may vary, the researchers suggest that sound characteristics inside should be taken into consideration in the development and promotion of incubators to preserve the hearing of premature infants.
虽然研究结果不能一概而论，但由于保温箱内部的声音可能会有所不同，研究人员建议在开发和推广保温箱时应考虑到内部的声音特征，以保护早产儿的听力。
