Correlation of Premature Infant Sleep/Wakefulness and Noise Levels in the Presence or Absence of "Quiet Time".

Background: Peak sound levels during sleep can compromise the development of hospitalized infants. Quiet time is a strategy implemented in neonatal units to promote the sleeping of neonates by reducing noise levels, luminosity, and handling during particular periods of the day.

Purpose: To determine the impact of quiet time on reducing sound levels and increasing total sleep time.
