The Effect of Noise Meters Giving Visual and Auditory Alarms Used on Reducing Noise in Neonatal Intensive Care Unit

INTRODUCTION: This study was conducted to determine the effect of the use of noise meter giving visual and auditory alarms on reducing noise.
METHODS: The study was conducted as experimental design a hospital in Neonatal Intensive Care Unit (NICU). In the study, a noise meter giving visual and auditory alarms and digital noise meter was placed in a room (Group 1); whereas, in the other room only digital noise meter was placed (Group 2). The noise meter giving visual and auditory alarms was hung on the most visible wall in the room and visual and auditory alarms were provided to the staff members in the room. The digital noise meter was hidden behind a closet in the same area in both rooms. Noise levels of the rooms were measured via the digital noise meter in both rooms in a way that data would come in 24/7 for two weeks.
RESULTS: It was found that the total mean noise level in Group 1 was significantly lower than Group 2 for two weeks (p<0.01). It was determined that the noise levels on weekdays and at the weekend were significantly lower in Group 1 than Group 2 in Week 1 (p<0.01); whereas, in Week 2 there was no difference between the groups in terms of the noise levels on weekdays and at the weekend (p>0.05).
DISCUSSION AND CONCLUSION: The use of noise meter giving visual and auditory alarms might be effective on reducing noise in NICU.
