Objectives. Noise in operating rooms (ORs) during surgery may affect OR personnel and pose a threat to patient safety. The sources of noise vary depending on the operation. This study aimed to investigate how OR staff perceived noise, whether music was considered noise and what its perceived effects were. Methods. Surgeons, anaesthesiologists, residents and nurses were interviewed. iPads were placed in the ORs to gather noise-level data. Results. Ninety-one interviews were conducted. Most participants (60.5%) reported the presence of noise and 25% the presence of music in the OR. Noise data from iPads registered levels ranging between 59.52 and 85.60 dB(A). ${\chi }^2$ analyses yielded significant results between participants’ role and the perceived effects of noise (p = 0.02). Responses to open-ended questions were thematically categorized. Conclusions. Surgeons generally chose the music played in ORs and were likely positively inclined to its effects, while anaesthesiologists and nurses minded the lack of choice and were more likely to consider it as noise.

目标。手术期间手术室 (OR) 中的噪音可能会影响手术室人员并对患者安全构成威胁。噪声源因操作而异。本研究旨在调查手术室工作人员如何感知噪音、音乐是否被视为噪音及其感知效果。方法。采访了外科医生、麻醉师、住院医师和护士。iPad 被放置在 OR 中以收集噪音水平数据。结果。进行了九十一次采访。大多数参与者 (60.5%) 报告手术室中存在噪音，25% 的参与者报告有音乐。iPad 的噪音数据记录在 59.52 和 85.60 dB( A ) 之间。${\chi }^{\mathrm{2个}}$分析在参与者的角色和噪音的感知影响之间产生了显着的结果 ( p  = 0.02)。对开放式问题的回答按主题分类。结论。外科医生通常会选择 OR 中播放的音乐，并且可能对其效果有积极的倾向，而麻醉师和护士则介意缺乏选择，并且更有可能将其视为噪音。
