Nursery ward is the safe place for premature after deliverey . It contains the basic
requirements of life to him. but full of noise caused by alarms of devices, conversations of
health team, ringing phones, and close the doors, exceeds what is reco
mmended by the
American Academy of Pediatrics in the Nursery wards 45 dBA (decibel A-weighting).
Although it stimulates the autonomic system leading to physiologic instability like
disorder in the level of oxygenation. We found in this study conducted on 30 premature
with pre and post test, that the level of noise within first hour of non interventions reached
67.2 dBA, level of oxygenation inversely with noise level in it, and reduction of noise level
under 45 dBA at second hour increases the oxygenation significantly. so we suggests to
make reduce noise interventions within daily practices of nursing procedures, and
subsequent research to study effect of noise on the rest of vital premature indicators.
