Objective: To compare the nurses’ mean score on noise control behaviour and the noise levels in the neonatal intensive care unit (NICU) before and after the implementation of the noise reduction guideline 

Design: One group quasi-experimental research with a pre-test and a post-test 

Methodology: The subjects were 18 registered nurses operating in the neonatal intensive care units of Bamrasnaradura Infectious Diseases Institute and Panyananthaphikkhu Chonprathan Medical Center.  The subjects’ implementation of the noise reduction guideline was promoted through education, mentorship, equipment support, poster reminders, and feedback. Three kinds of data were collected. First, the noise level in each of the NICUs was measured in two positions for two consecutive days, 24 hours per day. Second, information on each of the NICUs’ environment was recorded. Third, the nurses’ noise control behaviour was observed from two months before the implementation to two months after. Descriptive statistics, paired t-test and Wilcoxon signed-rank test were used for data analysis. 

Results: The subjects’ average post-implementation noise control behaviour score was significantly higher than their pre-implementation score (p < .05). The median noise levels in each critical care room (position 1) and the intermediate care room (position 2) were significantly reduced after the implementation (p < .01).

Recommendations: It is recommended that all of the healthcare professionals operating in the NICU be encouraged to apply this guideline to enhance their noise control capability and reduce noise levels in the NICU.
