Abstract：
Purpose: To evaluate the noise levels recorded in a hospital-based pediatric dental clinic and evaluate the occupational exposure personnel have to potentially hazardous levels of noise. Methods: A SoundAdvisor™ Sound Level Meter Model 831C was used to gather 19 days of background sound data (equivalent continuous sound levels, measured as LAeq) in the open bay, quiet room, sedation suite, and operating room settings. A Spartan™ Wireless Noise Dosimeter Model 730 (Larson Davis) was utilized to capture data about personal noise exposure of pediatric dental residents over 81 clinic sessions. Personal noise exposure was compared to the Occupational Safety and Health Administration (OSHA) stand- ard. Results: Background A-weighted sound pressure level was significantly less for the open bay than in the operating room, quiet room, and oral sedation setting (P<0.05), while the operating room was significantly less than the oral sedation setting (P=0.038). Personal LAeq was significantly less for the open bay than the quiet room (P=0.007) and oral sedation settings (P=0.007). There was a significantly larger percentage of time above 80 dBA captured in the oral sedation suite compared to the open bay (P=0.010) or operating room (P=0.023). Conclusions: Daily occupational noise exposure did not exceed the thresholds set forth by OSHA. Sedation and quiet room treatment settings were noted to be the loudest pediatric dental clinical environments.
摘要：
目的：评估医院儿科牙科诊所记录的噪声水平，并评估职业暴露人员对噪声的潜在危险水平。方法：使用SoundAdvisor™831C型声级计收集19天的背景声音数据（等效连续声级，以LAeq表示)在开放式海湾中，安静的房间,镇静套房,和手术室设置。使用Spartan™无线噪声剂量计型号730（LarsonDavis）来捕获有关81次诊所期间儿科牙科住院医师的个人噪声暴露的数据。将个人噪声暴露与职业安全与健康管理局（OSHA）标准进行比较。结果：开放海湾的背景A加权声压级明显低于手术室，安静的房间,和口服镇静设置（P<0.05），而手术室明显少于口服镇静（P=0.038）。开放海湾的个人LAeq明显低于安静的房间（P=0.007）和口服镇静设置（P=0.007）。与开放式间隔（P=0.010）或手术室（P=0.023）相比，口服镇静套件中捕获的超过80dBA的时间百分比明显更高。结论：每日职业噪声暴露未超过OSHA规定的阈值。镇静和安静的房间治疗设置被认为是最响亮的儿科牙科临床环境。
