To measure noise levels in a pediatric intensive care customer unit and discuss the consequences of such noise in relation to professional actions.


This is an observational and correlational study, performed in the pediatric intensive care unit of a federal hospital in Rio de Janeiro. We measured the noise level by decibel DEC-460 for five non-consecutive days and nights at five different hours. After a descriptive analysis of data, we performed a study of linear regression.


We identified an average of 62.64 dBA, with a standard deviation of 6.893 dBA and peak of 82.5 dBA during the daytime. The linear regression found that 44% of the variability of the noise is explained by the covariables.


The noise levels identified exceed recommendations of national and international organizations. We identified the professional actions and interactions as the main sources of noise.


There is an urgent need to rethink this environment and establish educational strategies for noise reduction, making it safer and healthier.
