“…Ward round mean sound levels in all four hospitals (1, 2, 3 and 4) were 64 dB, 64.5 dB, 67.1 dB, and 65.9 dB respectively, which was consistent with other studies done by Ramm [17] with 52.4 dB and Joshi and Tada, which was between 50 -95 dB. [18] The lowest sound level among day shifts was seen during the midnight shift within three hospitals (1, 2, and 3), 62.3 dB, 63.2 dB, and 65.1 dB, respectively. Another study detected the lowest measure at night with 61dB.…”

“…[20] Another study done in an urban city similar to this study with an increased number of neonates reported the mean sound level ranging 51 -95 dB, higher than the recommended level. [18] A study done in Portugal showed that noise levels were excessive in all the areas of the NICUs, exceeding the recommendation, with levels ranging between 48.7 dB to 71.7 dB. [18] The average level of noise was 11-14 dB above the recommendation of AAP.…”

Background Noise in the neonatal intensive care unit (NICU) has an impact on the developmental progress of neonates, especially preterm. Technology advancement has improved the life of preterm neonates, but also changed NICU into a noisy place. Objective To measure the noise levels and identify its sources in NICU at selected public hospitals in Kigali city` Methods A quantitative cross-sectional descriptive study. A sound level meter was used in recording the Sound level in six different locations of the NICUs at five different times. An observational checklist was used to identify possible sources of noise. Data were analysed using descriptive and inferential statistics (ANOVA). Results Sound levels recorded in all the NICUs were high ranging from 61.8 decibel (dB) to 77.0 dB, greater than the 45 dB recommended by the American Association of Pediatrics (AAP). The maximum noise level was 77.0 dB. Ward rounds had the highest noise levels, and lunchtime had the lowest noise levels in all hospitals. Noise levels were high at the station near the entrance in all NICU rooms. Conclusion In all NICUs, the noise level generated was greater than the standard limits established by AAP. Neonates need noise-free environment as excess noise has an impact on their wellbeing. Rwanda J Med Health Sci 2020;3(2):115-127

“…Joshi and Tada analyzed noise levels in NICU of urban hospital and found that the range of noise generated in NICU was between 50 dB and 95 dB. They also reported that the noise levels were maximum during the morning shifts as compared with other shifts [10]. Pinheiro et al identified sound pressure level at the NICU.…”

Background: Previous studies reported numerous adverse effects of noise in the newborns such as increase in the heart rate (HR) and respiratory frequency and drop in the oxygen saturation. Objective: The objective of this study was to study the effect of ambient noise levels in neonatal intensive care unit (NICU) on the hemodynamics of neonates. Materials and Methods: This was a hospital-based cross-sectional observational study which aimed at assessing the ambient noise levels in the NICU with a digital decibel meter and its effect on HR, respiratory rate (RR), and oxygen saturation. A total of 105 neonates (both preterm and term) having stable cardiorespiratory status were enrolled in the study. Results: The mean noise level recorded in the NICU was 56.2 dB. The lowest noise level was recorded at 8 am, that is, 46 dB while the highest recorded level was at 2 pm, that is, 65 dB in different areas of the NICU. There was a statistically significant increase in the HR in relation to the noise levels at all times (p<0.0001). The RR also showed a significant rise in relation to the increase in noise level (p<0.0001 at 2 pm with maximum noise level). The oxygen saturation showed a negative correlation and a statistically significant drop at 2 pm when maximum noise level was recorded (p<0.0001). Changing shifts and more number of healthcare personnel were important factors contributing to increased noise levels at 2 pm. Conclusion: Noise levels of >56 dB affected the hemodynamics of the newborn. The maximum increase in the mean HR, RR, and drop in saturation was observed at 2 pm. Staff sensitization and attitude change are needed to decrease the noise pollution in NICU.

“…1,2 In India, noise levels in NICU ranges from 60 to 90 Db. 3 Hence the prevalence of hearing loss is found to be 10 times higher in those neonates who were admitted to NICU compared to the neonates in the general population. 4 Foetus is only exposed to low intensity sounds in the uterus of the mother.…”

Background: The prevalence of hearing loss is higher in neonates admitted to NICU compared to the general population. Preterm babies are more vulnerable to the hearing damage due to their immature inner ear exposing them to various high frequency noises in the NICU to which they were not accustomed. Most NICU in India exceed the recommended sound levels. In order to reduce damage to the ears, foam-based earplugs are used to reduce the sound intensity reaching the ears of these premature babies.Methods: Babies admitted to NICU are allocated alternatively to receive earplugs or not. Cases are preterm babies with earplugs and controls are the ones without earplugs. The incidence of hearing loss is found by OAE testing of the ears at the end of NICU stay.Results: Out of 40 in each group, 6 babies in control group failed the OAE compared the 3 in the earplug group. Babies who did wear earplugs had longer period of NICU stay.Conclusions: Use of earplugs in babies admitted to NICU reduced the incidence of hearing loss and also length of NICU stay.
