Objective: to verify the sound pressure levels (SPL) and the influence of the shift and the occurrences in these levels in a neonatal unit in Rio de Janeiro. Method: longitudinal, exploratory, descriptive study. Collected from November 2021 to January 2022. Categorical variables were described using absolute and relative frequencies. To verify adherence to the normal distribution, the Shapiro-Wilk test was used. For the association between exposure and outcome variables, the Mann-Whitney, Kruskal Wallis and Qui-square tests were used. Results of p < 0.05 were considered statistically significant. Results: 10,122 decibel records and 56 events related to activities were collected, these occurred predominantly during the day. There was a variation from 38.6 to 93.1 decibels (dB). In 96.3% of the observed period, the NPS were above the recommended. Comparing the periods, nighttime had lower SPL (p=0.000). Conclusion: the registered NPS are above the recommended for a safe environment.
