This study was designed to describe the level of sound in acute patient care areas. A convenience sample of 25 subjects from four intensive care and two general care units within three hospitals in a large metropolitan area was studied. Continuous decibel levels [dB(A)] and equivalent continuous sound pressure levels [LEQ] were measured for 24 continuous hours. Two 3-hour observations were made to assess the sources of sound, and patients were interviewed to determine their perceptions of sound effects. Continuous high noise levels were found in the larger hospital's open heart recovery room and intensive care units [48.5-68.5 dB(A), 15-minute LEQ], lower levels in the smaller hospital's intensive care units [32.5-57 dB(A)] and varying levels in the general ward areas [34.25-62.5 dB(A)]. Decibel levels generated from equipment reached 90 dB(A) in some instances. Patients' perceptions ranged from content to highly perturbed. Although some sources of noise were not immediately changeable, other were adaptable, preventable, or reducible.
本研究旨在描述急性病患者护理区域的声音水平。对来自一个大都市地区三家医院的四个重症监护病房和两个普通护理病房的25名受试者进行了便利抽样研究。连续24小时测量连续分贝水平[dB(A)]和等效连续声压级[LEQ]。进行了两次3小时的观察以评估声音来源，并对患者进行访谈以确定他们对声音影响的感知。在较大医院的心脏直视术后恢复室和重症监护病房发现持续的高噪音水平[48.5 - 68.5 dB(A)，15分钟等效连续声压级]，在较小医院的重症监护病房噪音水平较低[32.5 - 57 dB(A)]，在普通病房区域噪音水平各不相同[34.25 - 62.5 dB(A)]。在某些情况下，设备产生的分贝水平达到90 dB(A)。患者的感受从满意到高度烦躁不等。虽然有些噪音来源无法立即改变，但其他一些是可以调节、预防或降低的。
