“…The values in figure 6 show that the incubator attenuates the environmental sound with approximately 12 dB, confirming the results from previous investigation [9]. The values in table 3 show that the sound levels generated by the environmental sound inside the incubator are below the limit values in terms of L eq , but exceed the limit values in terms of L max .…”

Excessive sound levels of preterm infants may contribute to negative physiological effects. Yet, recommended sound level limits are consistently exceeded at neonatal intensive care units (NICU), both inside and outside of the incubator. We present the results of a measurement campaign at two Norwegian hospitals with different design of the NICU. The first hospital had a shared unit with several incubators in one room while the second one featured single patient room. Sound pressure levels were measured continuously for several days inside of an unoccupied incubator and outside several active incubators. Additionally, sound pressure levels of an incubator were measured in a quiet room for several operation modes. The sound levels at both hospitals exceeded the recommended limit values. Although the incubator provides considerable attenuation of the environmental sound, the sound level inside the incubator was dominated by the contribution of the machine itself and exceeded the recommended limit values considerably. We conclude that the design of the NICU has some effect on the sound levels inside the incubator. However, without reducing the sound levels from the incubator itself, such measures have a minor effect on the infant exposure to excessive sound levels.

The Importance of Noise Attenuation Levels in Neonatal Incubators

Background: It is known that high noise levels can be harmful to preterm infants, causing physiological and psychological disorders. It is also known that premature babies spend a lot of time in an incubator. In this sense, many studies show that incubator noise levels can range from 45 to 70 dB. However, these differences in noise levels depend, fundamentally, on the wide range of methodology that can be used. This study aims to know the levels of noise from a fan in the incubator itself and how much it can isolate the noises coming from the outside. Methods: For this purpose, the noise levels of three incubators were measured within a sound-dampened booth for free-field audiometry. For the emission of acoustic energy, a pink noise generator was used; likewise, two microphones were placed, one inside the incubator cabin and the other outside, to determine the acoustic insulation levels of the tested incubators. Results: The incubators produced equivalent continuous sound pressure levels between 53.5 and 58 dB. Acoustic insulation analysis showed that levels varied from one incubator to another, between 5.2 and 10.4 dB. Conclusions: It is necessary to improve the acoustic insulation inside the incubator cabin and to reduce the noise levels of the motor fan. On the other hand, although the incubators are meeting the noise criteria set out in the IEC60601-2-19: 2009 standard of 60 dBA, under normal use conditions, they are still far from the limit recommended by the American Academy of Pediatrics (45 dBA).

“…Furthermore, the structure of infants’ immediate surroundings presents additional challenges. Many preterm infants require an incubator which significantly attenuates speech and impairs direct, naturalistic verbal communication that influences neurocognitive development (Newman, 1981; Wubben et al, 2011).…”

Exposure to high quantity and quality of language in the neonatal period is critical to neurocognitive development; however, Neonatal Intensive Care Unit (NICU) environments may contribute to language deprivation. Using qualitative thematic content analysis, this study aimed to characterize the knowledge and attitudes of NICU staff and patient families toward the importance of early language experience, the current NICU language environment, and the benefits and barriers of communication in the NICU. Results revealed that all respondents recognized the importance of communication for optimal cognitive development, though few understood why. Staff and family members alike recognized the role of nurses as coaches and role models in promoting communication at the bedside. Nurses generally felt that family members communicate less with their babies than family members themselves perceived, and that cell phone use has fewer communicative advantages than parents perceive. Respondents reported that patient illness, lack of time, and intimidating equipment all raise barriers to communication. These findings yield important considerations for developing educational interventions to improve NICU language environments, including a synergistic, dual focus on both staff and families. Communication in the NICU is a low cost, feasible, and accessible target with aims of ensuring optimal neurocognitive development for at-risk children.
