Abstract: (980 Views)
Background: The comfort of patients during their stay in the hospital is important, and noise pollution exceeding the permissible level could cause discomfort for the patients and intensify their disease. Moreover, increase in this factor affects the hospital staff and therefore has a negative effect on how they serve the patients. Thus, the aim of this study was to assess the environmental noise pollution in Feiz Hospital wards and its adjacent area, and compare them with recommended standard values. Methods: This cross-sectional study was carried out in 2011. To measure sound levels, the environmental noise parameters such as L10, L50, L90, L95, L99, Leq, SEL, SPL, Lmin, Lmax, were measured using the CEL-440 sound level meter. Measurements were conducted during 8-12 a.m. and 16-20 p.m. with half an hour interval. Findings: The maximum equivalent sound level (Leq) in the clinical section in the morning, and in the official section of the hospital in the afternoon were 66.72 and 65.80 dB (A), respectively. The averages of Lmax, Leq, SEL, and L10 in the morning were 61.87, 58.17, 61.50, and 60.62 dB, respectively, and those of in the afternoon were 69.67, 62.06, 71.58, and 64.87 dB, respectively. Conclusion: Statistical analyses showed a significant difference between measured values in the morning and the afternoon (P < 0.001). In other words, the mean index values in the afternoon were higher than in the morning. It can be concluded that Feiz Hospital has a high level of noise pollution, and in most cases the noise levels exceeded the levels recommended by the Iranian environmental protection agency.
