Noise is recognized as a source of hazard to the patient's environment. Studies have also shown that it has a direct impact on mortality and morbidity as a result of sleep deprivation which affects the immunity of critically ill patients. The aim of this study was to measure levels of environmental noise in different departments in three different time shifts in working days in three floors with basement area. On statistical analysis the result shows that there was significant difference in the noise level among all the floors across all the three time shifts except the basement area. The noise level was found to be higher than the standardised level. This needs to be taken care for the basic modification in construction of the area in hospital setup along with the usage of sound dampers in larger context to meet the standards. Further research in this area might focus on the noise level and other modifiable environmental stress factors in the hospital setup to explore its effect on physician, hospital staff and patients.
