Abstract
Noise pollution in the human environment has different physical and psychological effects on humans. The aim of this study is to assess the extent of novelty and its sources in the intensive care unit of burns. Sound measurement was carried out during 24 engineering industry organizations in the care research department at Shahid muthari burn hospital in Tehran. Sound pressure measurements were measured in two patient rooms and inpatient corridor in two shifts a day (first and second shifts) and at night. Based on these measurements, the rate and sources of novelty, mean and maximum sound pressure levels were analyzed in three different time periods during the day and at night. It was found that the acoustic pressure alignment of patients ' rooms and the inpatient ward corridor exceeded the level of WHO guidance. In general, it can be stated that the level of novelty in the intensive care unit of burns during the day is higher than at night. Also, the level of novelty alignment was higher in the room of patients who were in better condition in terms of level of consciousness and were able to scream. The dominant sources of novelty in the intensive care unit were burns, the screaming of patients, the conversation and activity of the treatment staff, the sound of closing doors, alarms and the sound of medical equipment. Therefore, the design of single-board hospital rooms for burn patients and the use of sound-absorbing materials in hospital rooms can greatly control the noise pollution caused by the screaming of patients and the conversation of the treatment staff during the replacement of the dressing. Undoubtedly, implementing such corrective considerations will provide better conditions for the environment in question, and hospital managers are expected to have the necessary planning for corrective measures.
