1、呼吸内科病区噪声的监测与分析［摘要］目的了解呼吸内科病区的噪声状况，为控制病房噪声，采取干预措施提供参考。方法应用噪声测量仪连续动态测量呼吸内科病区72h的每小时等效声级、最大声级、最小声级及各种噪声源的A声级。结果呼吸内科病区昼间与夜间噪声强度都超过规定标准，其中护士站的等效声级高于病房，差异有统计学意义(P<0.05)o交流说话声、呼叫声、电视机及收音机播放声、吸痰声、输液架及床护栏碰撞声等噪声源均超过80dB,成为呼吸内科病区的主要噪声来源。在设置相同床位数的基础上，有危重患者的病房噪声水平高于无危重患者的病房；在普通病房中，3人间、4人间病房的噪声水
2、平高于2人间，差异有统计学意义(P<0.05)o结论呼吸内科病区的噪声水平超过我国和WHO规定的标准，存在有多种来源的噪声。护士站、危重患者和床位数设置较多的病房应作为噪声控制的重点对象。［关键词］呼吸内科；噪声；监测［中图分类号］R473.5［文献标识码］A［文章编号］1673-7210(2014)04(a)-0083-04InvestigationandanalysisofnoiseinRespiratoryMedicalWardRONGGennanDepartmentofNursing,HuashanHospitalBaoshanBranchAffil
