The purpose of this study was to determine the effects of individual noise reduction using silicone earplugs for very low birthweight newborns in neonatal intensive care on growth and development. The study hypothesis was that newborns who were randomized to the earplug group would be heavier than controls at 34 weeks post-menstrual age.
