Abstract

Introduction: The incorporation of technologies in the care of infants has contributed to in-creased survival; however, this has turned neonatal unit into a noisy environment.

Objective: To evaluate the physiological and functional effects resulting from the exposure to noise on low-weight newborns in incubators in a neonatal unit.

Methods: Prospective, observational, quantitative, exploratory, descriptive study. The adopted statistical method included tables of frequency, descriptive statistics, and Student’s t-test, with a OHYHORIVLJQLÀFDQFH$VGDWDFROOHFWLRQWRROVWKHHQYLURQPHQWDOQRLVHDQGWKHQRLVHLQVLGHRI WKHLQFXEDWRUZHUHHYDOXDWHGDQGWKH$VVHVVPHQWRI3UHWHUP,QIDQW%HKDYLRUVFDOHZDVXVHGWR DVVHVVSUHPDWXUHQHZERUQEHKDYLRUDQGSURMHFWHGVSHFLÀFDOO\WRGRFXPHQWWKHQHXUREHKDYLRUDO IXQFWLRQLQJRISUHWHUPLQIDQWV7KHGDWDFROOHFWLRQRFFXUUHGIURP6HSWHPEHURIWR$SULORI 2013; 61 low-weight newborns admitted in the neonatal unit and in incubators were observed.
