RODRIGUEZ-BALDERRAMA, Isaías et al. Talking by the side of the patient increases the decibels in the NICU of a tertiary hospital. Perinatol. Reprod. Hum. [online]. 2022, vol.36, n.2, pp.46-50.  Epub Dec 01, 2022. ISSN 2524-1710.


Loud sound has a negative impact on the health of the neonate in the short and long term. Its reduction is a problem in the newborn intensive care unit (NICU).


To determine the decibel levels inside and outside the incubator before and after speaking in the NICU of a tertiary care hospital.

Material and methods:

An experimental, analytical, prospective, cross-sectional study was carried out, accepted by the ethics committee. Decibels were measured before and after speaking inside and outside the incubator, and decibel levels were compared between shifts.


When comparing the average decibels inside the incubator before speaking, we found an average of 60 ± 3.8 and after speaking 65 ± 4 being statistically significant (< 0.001). The total average of decibels outside the incubator before speaking was 64.1 ± 3.7 and after speaking 69.1 ± 3.9 being statistically significant (< 0.001).


After talking and comparing the decibels inside vs. outside, we found that outside the incubator is 4 decibels higher than inside (p < 0.001). When comparing the shifts, the evening shift was the noisiest and the night shift the least.
