Noise sources and levels were evaluated in a six-bed intensive care unit (ICU) in Athens, Greece. Ten patients (six males, four females) completed specifically designed questionnaires, and at the same time nine 8-h sound measuring sessions took place. A Bruel and Kjaer 2231 sound-meter was used on the decibel-A scale combined with observation. Human activity, operating equipment and construction engineering of the hospital building were identified as sources of noise. Noise levels were elevated [LEQ = 60.3-67.4 dB(A)]. No reliable information was obtained from the questionnaires. ICU noise levels were higher by 27 dB(A) than recommended hospitals levels. To counteract noise pollution in ICUs, staff awareness and sensitivity are needed.
在希腊雅典的一个有六张床位的重症监护病房（ICU）中对噪声源和噪声水平进行了评估。十名患者（六名男性，四名女性）填写了专门设计的问卷，同时进行了九次时长为8小时的声音测量。使用了Bruel和Kjaer 2231声级计以A声级进行测量并结合观察。已确定人类活动、操作设备以及医院建筑的建设工程为噪声源。噪声水平有所升高[等效连续A声级（LEQ）= 60.3 - 67.4分贝（A）]。从问卷中未获得可靠信息。ICU的噪声水平比医院推荐水平高出27分贝（A）。为了应对ICU中的噪声污染，需要提高工作人员的意识和敏感度。
