摘要

This one-group pre-post test design was to evaluate sound distribution and sudden peak noise frequencies (SPNs) and the associated events after using a noise-sensor light alarm in a tertiary neonatal intensive care unit (NICU). The alarm is activated as the sound level reaches ≥ 65 A-weighted decibel (dBA). The environmental sound level was monitored continuously for a period of 1 week before and 1 month after using the alarm. The mean sound level in the incubator of patients receiving ventilator support before and after using the device were 58.0 ± 0.6 and 56.4 ± 0.7 dBA (t = 8.619; p < 0.001), whereas those at the radiant heated bed were 58.0 ± 2.4 and 58.1 ± 2.0 dBA (t = 0.715; p = 0.476). The percentage of observation time of sound levels < 58 dBA increased by 28% in the incubator and 4% at the radiant heated bed (p < 0.001). Episodes of SPN decreased from 630 to 185 times/d in the incubator and from 2069 to 748 times/d at the radiant heated bed after using the device. The noise-sensor light alarm effectively reduces sound level and episodes of SPN in the NICU. This may alleviate stress of noise for newborns with critical illness.
