Background and Aim: Noise is the most common source of environmental stress that influences negatively the psychological and physiological aspects of human. The purpose of this study was determining the noise sources and assessing in General Intensive Care Unit. Materials and Methods: In this cross-sectional study, equivalent noise level "Leq 15 min", Maximum and Minimum sound pressure level were measured on 5 stations, during the all of day and night shifts period in different place including corridor, nursing station, rest room and hospitalization parts. The data were processed by means of SPSS and Excel software. Results: Mean sound pressure level for GICU was 60.9±1/6 dBA that is more than the standard level. The mean of maximum noise level was obtained 82.5±2 dBA and the highest noise level was measured at nursing station. There was significant difference in Noise Pollution level based on different months, level of patient's conciseness and number of ventilator using (P < 0.05). Conclusion: Being more noise pollution in the ICU and stations on all shifts may cause to diminish health and well-being of the staff in long-term and produce some problems for the patient. According to the highest level of noise produced in nursing stations and the different activities doing by the staff as a main noise pollution factor, it's necessary to perform required training in relationship with doing the works in right manner so that we can produce quiet and silence environment for patience.
