Abstract

MACEDO, Ivan Senis Cardoso et al. Noise Assessment in Intensive Care Units. Braz. j. otorhinolaryngol. (Impr.) [online]. 2009, vol.75, n.6, pp.844-846. ISSN 1808-8694.  https://doi.org/10.1590/S1808-86942009000600012.

Intensive Care Units are environments with numerous noise sources. In different hospital environments it is recommended to have a sound pressure level between 35 and 45db(A). AIM: To measure the sound pressure levels in three ICU at a hospital in Jundiaí, State of São Paulo, Brazil. STUDY DESIGN: Observational. MATERIALS AND METHODS: we used a Minipa model MSL1532C (USA) sound meter, according to the Brazilian Technical Standards (NBR 10151), in order to measure sound levels in the ICUs at different moments, that is, the morning, afternoon and night at peak times of activity. RESULTS: The values found during the checking of the sound pressure levels were 64.1dB (A) in the First ICU, 58.9 dB (A) in the Coronary Unit and 64dB (A) in the second ICU. CONCLUSION: High sound pressure levels in ICU still mean an important health-related problem for patients in these units. None of the three ICU pad levels above 85dB, showing that there is no occupational risk for the health care teams in the environments studied.

Keywords : environmental statistics; noise; intensive care units.
