Sound exposure in a purpose built, single room configured neonatal unit - A survey of clinical neonatal staff

Year: 2025

Type: article

Abstract: Sound levels in neonatal units continue to exceed recommendations. Elevated sound exposures experienced by preterm infants may contribute to poorer neurodevelopmental outcomes. A 10-question survey assessed neonatal clinicians’ opinions and awareness of sound intensity and exposures in a single room configured neonatal unit; and sound level recommendations. Seventy-three of 122 (60%) clinicians responded to the survey. Respondents rated 12 equipment items or activities within the range of moderately to extremely loud, although 81% (n = 59) either strongly or moderately agreed single rooms reduced sound levels. Less than 50% strongly agreed that loud sounds disrupt growth and development. Only 41% ( n = 30) and 27% ( n = 20) were aware of recommended average and peak sound levels respectively. Clinicians were able to subjectively rate sound intensity, however most lacked awareness of sound level recommendations. Sound levels and exposures were high with the prominent sources of excessive sound arising from essential neonatal equipment.
