“…In a study carried out in maxillofacial ORs, average sound level was 58 dB(A), and levels peaked at a maximum of 117.4 dB(A) when power tools and suction were used. 22 Kulkarni et al 23 investigated the intensity of the noise in oral and maxillofacial surgery ORs and clinical settings and suggested that the mean intraoperative noise level for nondrilling periods was 64.3 dB (maximum 94.8 dB), and for drilling periods, it was 66.78 dB (maximum 89.0 dB). Jenkins et al 24 studied ambient noise and distracting events during caesarean operations and reported the mean noise levels in three phases of surgery as follows: 62.5 ± 3.9, 63.9 ± 4.1, and 66.8 ± 5.0 dB.…”

The research was conducted to evaluate the noise levels and the effect of noise on the workload and stress levels of the operating room (OR) staff of a public hospital. Design: Descriptive and cross-sectional study. Methods: The data were obtained by measuring ambient noise during 403 orthopaedic, urological, and general surgeries on weekdays between July and October 2019. We measured the noise by dividing the surgery into three phases. These phases are as follows: from the entry of the patient, induction of anesthesia, and preparation of the surgical area until the start of the procedure (Phase I), from the incision until the completion of closure and dressing application (Phase II), from the completion of closure and dressing application until the exit of the patient (Phase III). Furthermore, the workload and stress levels of 45 OR staff who work in the general surgery, orthopaedics, and urology ORs were measured. Data were collected using a CA 834 noise measurement device, State-Trait Anxiety Inventory (STAI Form TX-I), the National Aeronautics and Space Administration (NASA) Task Load Index Workload Scale, and Information form related to surgery and ORs. Findings: The noise in the OR was higher than 35 dB, A-weighted [dB(A)], the limit proposed by the World Health Organization for hospitals. Phase I average noise level was 63.00 ± 3.50, Phase II average noise level was 62.94 ± 3.75, and Phase III average noise level was 63.67 ± 2.81. The mean anxiety score was 34.50 ± 6.09. The total workload level was found to be 56.91 ± 15.67. Anxiety scores and workload scores had positive weak and moderate correlations with noise levels (P < .01). Conclusions: The noise in the OR was high, and anxiety scores and workload scores correlated positively with noise levels.

“…[6][7][8][9][10] Several studies have reported the sound pressure levels for a particular surgery or specific surgeries. [11][12][13][14][15][16] However, it is difficult to characterise noise in the OR based on these published articles. Previous studies were limited to surgical tools and specific surgeries; thus, it is not surprising A cross-sectional study in a tertiary care hospital in China: noise or silence in the operating room Open Access that the typical patterns in sound pressure levels over the course of a workday within an OR cannot be characterised.…”

ObjectivesThis study aims to provide a comprehensive description of noise levels in operating rooms (ORs) in a tertiary care hospital in China. Additionally, the study aims to examine the deviation in noise levels from international and internal standards as well as the differences in noise levels by category of surgery and day of the week.MethodsWe monitored noise levels in 23 ORs in a tertiary care hospital in China between August 2015 and March 2016. Dosimeters were used to determine noise levels. The noise data collected in the dosimeter were downloaded to an IBM computer for subsequent analysis. One-way analysis of variance and Student’s t-test were used to examine the differences in noise levels.ResultsThe noise level in the ORs ranged between 59.2 and 72.3 dB(A), with 100% of the measurements exceeding the recommended hospital noise standards. There was substantial similarity in noise levels from Monday to Friday (F=1.404, p=0.234), with a range between 63.7 and 64.5 dB(A). The difference in noise levels by category of surgery was significant (F=3.381, p<0.001). The results of the post hoc analysis suggested that ophthalmic surgery had significantly higher noise levels than otolaryngological surgery or general surgery.ConclusionsOphthalmic surgery had significantly higher noise levels than otolaryngological or general surgeries. High noise levels were identified in all evaluated ORs during weekdays, and these levels consistently exceeded the currently accepted standards. These findings warrant further investigation to determine the harmful effects of noise on both patients and staff in ORs.

“…Five studies measured noise levels from the position of the surgeon's ear or shoulder [18,23,30,36,37]. Three studies measured noise levels from a position close to the burr or patient's ear [3,24,31] and one study did not specify the location of noise measurement [20]. In OHNS cadaver labs, five studies measured noise levels from a position on a segment of temporal bone [22,28,29,32,33] and four studies from a position within the external auditory canal (EAC) of the cadaver [27,34,35,39].…”

“…Operating rooms (OR) are noisy. Surgical equipment, monitors, heating ventilation and air conditioning (HVAC) systems, music and team member communication all contribute to noise pollution in the OR [1][2][3][4][5][6]. OR noise pollution can negatively impact surgical technique and team communication [7,8].…”

Objective Noise in operating rooms (OR) can have negative effects on both patients and surgical care workers. Noise can also impact surgical performance, team communication, and patient outcomes. Such implications of noise have been studied in orthopedics, neurosurgery, and urology. High noise levels have also been demonstrated in Otolaryngology-Head and Neck Surgery (OHNS) procedures. Despite this, no previous study has amalgamated the data on noise across all OHNS ORs to determine how much noise is present during OHNS surgeries. This study aims to review all the literature on noise associated with OHNS ORs and procedures. Methods Ovid Medline, EMBASE Classic, Pubmed, SCOPUS and Cochrane databases were searched following PRISMA guidelines. Data was collected on noise measurement location and surgery type. Descriptive results and statistical analysis were completed using Stata. Results This search identified 2914 articles. Final inclusion consisted of 22 studies. The majority of articles analyzed noise level exposures during mastoid surgery (18/22, 82%). The maximum noise level across all OHNS ORs and OHNS cadaver studies were 95.5 a-weighted decibels (dBA) and 106.6 c-weighted decibels (dBC), respectively (P = 0.2068). The mean noise level across all studies was significantly higher in OHNS cadaver labs (96.9 dBA) compared to OHNS ORs (70.1 dBA) (P = 0.0038). When analyzed together, the mean noise levels were 84.9 dBA. Conclusions This systematic review demonstrates that noise exposure in OHNS surgery exceeds safety thresholds. Further research is needed to understand how noise may affect team communication, surgical performance and patient outcomes in OHNS ORs. Graphical abstract
