SUMMARY:

Introduction: Hospital noise is a significant component of the care environment, with potential impacts on the health, well-being, communication, and performance of healthcare professionals. Objective: To analyze healthcare professionals’ perceptions of hospital noise and its self-reported effects on health and work performance, to characterize noise levels in patient care areas, and to evaluate the effects of different strategies for reducing noise. Method: The dissertation was structured into two articles. The first study was a quantitative, descriptive, and analytical study conducted with 64 healthcare professionals, which investigated perceptions of and annoyance caused by noise, auditory and non-auditory symptoms, and perceived impacts on work performance. In addition, 22 individual noise exposure measurements were taken during the workday. The second study was a cluster-randomized trial in which three hospital wards were assigned to different conditions: in-person educational intervention, real-time visual feedback on sound levels, or control. Equivalent sound pressure levels (LAeq) and maximum sound pressure levels (Lmax) were assessed at baseline and post-intervention. The data were subjected to descriptive and inferential statistical analyses, including correlation analyses and between-group comparisons in the first study and mixed linear models in the second, using a significance level of 5%. Results: In the first study, higher perceived noise intensity was associated with self-reported symptoms and impacts on work performance, and the measured sound levels exceeded the recommended values for hospital environments, with differences observed between work shifts but not between departments. In the second article, a significant interaction between sector and time was observed for LAeq (p=0.020), indicating differences in the evolution of sound levels among the sectors. The ICU, which underwent the visual feedback intervention, showed a reduction in LAeq, with a change that was significantly different from that observed in the Vascular Clinic (the control group) (p=0.017) and the Integrated Clinic, which underwent the in-person educational intervention (p=0.019). There was no difference between the changes observed in the Integrated Clinic and the Vascular Clinic (p=0.452). For Lmax, no significant differences were observed between the departments. Conclusion: Hospital noise was associated with symptoms and perceived impacts on work performance. Among the strategies evaluated, the unit that received visual feedback showed the greatest reduction in LAeq compared to the in-person educational intervention and the control group, indicating the potential of this strategy for managing hospital noise, given the specific characteristics of the units evaluated.
