Noise pollution in the operating rooms is one of the remaining challenges. Both patients and physicians are exposed to different sound levels during the operative cases, many of which can last for hours. This study aims to evaluate the noise pollution in the operating rooms during different surgical procedures.
In this cross-sectional study, sound level in the operating rooms of Hamadan University-affiliated hospitals (totally 10) in Iran during different surgical procedures was measured using B&K sound meter. The gathered data were compared with national and international standards. Statistical analysis was performed using descriptive statistics and one-way ANOVA, -test, and Pearson's correlation test.
Noise pollution level at majority of surgical procedures is higher than national and international documented standards. The highest level of noise pollution is related to orthopedic procedures, and the lowest one related to laparoscopic and heart surgery procedures. The highest and lowest registered sound level during the operation was 93 and 55 dB, respectively. Sound level generated by equipments (69 ± 4.1 dB), trolley movement (66 ± 2.3 dB), and personnel conversations (64 ± 3.9 dB) are the main sources of noise.
The noise pollution of operating rooms are higher than available standards. The procedure needs to be corrected for achieving the proper conditions.
手术室中的噪音污染是尚存的挑战之一。在手术过程中，患者和医生都会接触到不同的声级，其中许多手术可能持续数小时。本研究旨在评估不同外科手术过程中手术室的噪音污染情况。
在这项横断面研究中，使用B&K声级计测量了伊朗哈马丹大学附属医院（共10家）手术室在不同外科手术过程中的声级。将收集到的数据与国家和国际标准进行比较。使用描述性统计、单向方差分析、t检验和皮尔逊相关检验进行统计分析。
大多数外科手术的噪音污染水平高于国家和国际记录标准。噪音污染最高水平与骨科手术相关，最低水平与腹腔镜和心脏手术相关。手术期间记录的最高和最低声级分别为93分贝和55分贝。设备产生的声级（69±4.1分贝）、推车移动（66±2.3分贝）和人员交谈（64±3.9分贝）是主要噪音来源。
手术室的噪音污染高于现有标准。需要对该情况进行纠正以达到适当条件。
