Expense, noise, and bright lighting have been acknowledged disadvantages of ICU's since their establishment. Data are available regarding the first, but not the latter two disadvantages. Background sound levels were measured in four units and found to be comparable to the hospital cafeteria at noon, and only somewhat less noisy than the boiler room. Sound levels generated by numerous components of the environment were measured and related to the total noise level. Noise levels generated by seven different nebulizers, each used at three different settings, were found to show noteworthy differences. High noise levels have been shown to have adverse physiological and psychological effects on patients and on the errorproneness of intensive care personnel. If noise generation is a consideration in selection of equipment, industry can respond appropriately. Further studies can lead to measures that will reduce the noise level in ICU's.
自重症监护病房（ICU）设立以来，费用、噪音和明亮的灯光一直被认为是其缺点。有关于第一个缺点的数据，但对于后两个缺点却没有相关数据。对四个病房的背景声音水平进行了测量，发现其与医院中午的自助餐厅相当，仅比锅炉房稍微安静一点。对环境中众多组件产生的声音水平进行了测量，并将其与总噪音水平相关联。发现七种不同的雾化器在三种不同设置下使用时产生的噪音水平存在显著差异。高噪音水平已被证明会对患者以及重症监护人员的易出错性产生不利的生理和心理影响。如果在设备选择时考虑噪音产生问题，行业可以做出适当回应。进一步的研究可以带来降低ICU噪音水平的措施。
