The increase of noise level is a problem which has been currently identified in health institutions. The general goal of this study is to assess noise environment as well as the noise perception of nursing team and administrative staff in the emergency room. It is a descriptive quantitative study. Noise perception was evidenced by means of a questionnaire applied during an interview. Fifty-nine (59) professionals participated in the study, being 38 from the nursing team and 21 from the administrative staff. In order to evaluate noise level, a calibrated Bruel & Kjaer 2230 Integrating Sound Level Meter was used. Results showed that both teams perceived to be more exposed to biological, ergonomics and accident hazards than to physical hazards. Noise was spontaneously mentioned as a physical hazard by 8.4% of the participants. The most reported health problems by the professionals were fatigue, stress, anxiety and irritability. The professionals correlated these health problems with occupational reasons rather than extra occupational ones. Noise levels measured Leq. dB(A) ranging from 56.6 to 68.8 dB(A), high above the recommended comfort levels for hospital settings. Nursing professionals can better identify noise produced by equipment, while the administrative staff can better identify noise produced by people. Noise produced by people is the one that really bothers them. Afternoon shift is the noisiest, which was evidenced in the several noise level measurements, and ultimately perceived by the administrative staff. Only the administrative staff reported concentration and communication difficulties due to the noise. The nursing team stated that they produce noise that may bother others while the administrative staff denied this fact. The teams recognize hearing loss as the greatest harm caused by noise. Mentioned prevention attitudes were the use of ear protectors and avoidance of noisy places. It can be concluded that participants perceive emergency settings as noisy; nursing professionals are more disturbed by noise, but administrative staff refers to difficulties in carrying out their tasks due to noise. Both teams perceive hearing loss as one of the harmful effects caused by noise and mention stop talking as one of the attitudes to avoid noise. All noise measurements are above the acoustic comfort level established by noise guideline 10,152/1987.
