SOUND ANALYSIS OF NOISE POLLUTION IN OPERATING ROOMS

Noise in operating rooms (OR), recovery rooms and intensive care units is a hazard to surgeons, anaesthetists, personnel and patients. OR noise can reduce the mental efficiency and short-term memory of anaesthesia residents. Excessive exposure to noise pollution may be also an important cause of sleep disruption for conscious patients in the hospital. The paper refers to case studies carried out in OR and intensive care units of some Tuscan general hospitals. The structure of buildings has been considered and all the related characteristics of sound propagation towards sensitive receivers, workers and patients, in the operating theatre are analysed, using procedures for sound measurements reported by ISO and EC standard. The workgroup is composed of anaesthetists and acoustic engineers, joining their experiences and approaches.
