The goal was to identify sound pressure level (SPL) at the neonatal intensive care unit (NICU) and inside the incubator of a teaching hospital of a public university from São Paulo - SP, Brazil. SPL inside the NICU and the incubator were measured using four dosimeters in January/2010. SPL at the NICU varied from 52.6 dBA to 80.4 dBA and inside the incubator, from 45.4 dBA to 79.1 dBA. SPL both at the NICU and inside the incubator are above the recommended values, but levels were higher at the NICU than inside the incubator. Although there are some specific factors related to SPL inside the incubator, the NICU and incubator acoustic features present a system: an increase/decrease in SPL at the NICU usually tends to increase/decrease SPL inside the incubator. The study points to the need for simultaneous monitoring of SPL at the NICU and inside the incubator.
目标是确定巴西圣保罗州一所公立大学教学医院新生儿重症监护室（NICU）以及保育箱内的声压级（SPL）。2010年1月，在NICU和保育箱内使用四个剂量计测量了声压级。NICU内的声压级在52.6 dBA至80.4 dBA之间，保育箱内的声压级在45.4 dBA至79.1 dBA之间。NICU和保育箱内的声压级均高于推荐值，但NICU内的声压级高于保育箱内。尽管保育箱内的声压级存在一些特定因素，但NICU和保育箱的声学特征呈现出一种系统：NICU内声压级的增加/降低通常会导致保育箱内声压级的增加/降低。该研究指出需要同时监测NICU和保育箱内的声压级。
