RÉSUMÉ
Objective@#To measure the levels of environmental noise in the medical intensive care unit, surgical intensive care unit, and adult ward of the Makati Medical Center for the morning, afternoon, and evening shifts, on weekdays and weekends, and to compare noise levels across shifts, and between weekdays and weekends. @*Methods@#Design: Environmental Noise Survey. Setting: Tertiary Private Training Hospital. Participants: None. @*Results@#The overall mean environment noise levels in all the areas surveyed (medical intensive care unit, surgical intensive care unit and adult ward) exceeded World Health Organization recommendations by more than 20 dB across different working shifts on both weekdays and weekends. There was no significant difference in noise levels between weekdays and weekends across shifts in all areas, except for the afternoon shift in the Medical ICU. Using Repeated Measures ANOVA, results showed that there is no sufficient evidence to conclude that at least one shift has significantly different mean noise level in any of the 3 areas (MICU: F(2)=4.73, p-value=.1124; SICU: F(2)=7.91, p-value=.0540; WARD: F(2)=2.73, p-value=.1948) @*Conclusion@#The overall environmental noise levels in the different areas of MICU, SICU and Adult ward exceeded the WHO recommendation. It is recommended that a change in strategy is needed for prevention of environmental noise, setting guidelines and policies to assure quality health care and noise control. Further investigations to ascertain exact sources may give rise to feasible solutions.
