PURPOSE: To determine noise levels in different hospital settings and investigate the impact of noise exposure on the quality of life of the healthcare workers in these environments. METHODS: Noise was measured using a sound level meter in different sectors of the Sao Paulo university hospital (neonatal intensive care unit, nutrition, classrooms, print shop, laundry, carpentry shop and metalwork shop) in different periods of the day (morning, afternoon and night) over a one-week period. Five workers from each sector were asked to fill out questionnaires on hearing habits and quality of life (WHOQoL-Bref), adapted to Brazilian Portuguese. Each question on the WHOQoL-Bref was scored from 0 to 5 points, with higher overall scores denoting better quality of life. RESULTS: Statistically significant differences among environments were found regarding minimum and maximum sound levels, regardless of the time of the day. All sound levels were considered harmful. No statistically significant differences among sectors were found in the overall quality of life score or subscales of the WHOQoL-Bref (Quality of Life, Physical Aspects, Psychological Aspects, Social Relations and Environment). CONCLUSION: The minimum and maximum noise levels in all sectors, except the neonatal intensive care unit, exceeded those defined for hospital environments. The variation in noise levels characterizes environments with intermittent noise that places the auditory health of the employees at risk. The noise levels encountered demonstrate the need for a hearing conservation program involving both group and individual measures.
