In large urban centers can be seen that the noise level is so high that it threatens the physical and psychological integrity of the inhabitants. However, it is observed that much of the noise in the hospital environment is originated from within hospital, and one of the main sources of noise in the units is caused by the communication by hospital’s staff and the equipment. The noise-induced hearing loss (NIHL) is one of the consequences that loud noise can affect health, among other damage. Thus, the hospital environment should be calm and quiet becomes noisy and stressful environment, increasing anxiety and pain perception in the patient, reducing sleep and extending convalescence. Objective: Evaluate the acoustics of the main environments in units urgency and emergency in the city of Belém, Pará State, Brazil. Check the adequacy of health standards and technical regulations, with the simulation of a pilot ambience validated using the ODEON software and propose virtual solutions from conditioning acoustic. Material and Methods: we used the equipment Sound Level Meter with calibration certificate of the Brazilian Calibration Network (RBC) for measurement of NPS during daytime and nighttime, in accordance with the NBR 10.151 (2000), and the observation and identifying sources of noise environments. Results: The values obtained during the measurements of NPS in environments Hospital were 58 dB(A) to 70 dB(A) and Hospital B were 62 dB(A) to 70 dB(A). The pilot environment was selected according to the results and with the residence time of the health care team and patients. Conclusion: was developed the computational model validated the pilot environment, generating a proposed model with architectural interventions aimed at the acoustic comfort of the health care team and patients. The environments surveyed did not have noise levels above 85 dB (A), proving that there is no risk to occupational health teams. However, the high levels of noise are responsible for stimulating or even trigger a variety of symptoms that affect the working capacity of the health team, in addition to increasing convalescence and impair the recovery of patients.
