PurposeThis study compared sound levels before and after structural reconstruction within an NICU.Study Design And MethodsUsing a descriptive design, sound level recordings (in decibels, A-weighted scale) of the Leq, L10, and Lmax were measured continuously for 8 hours (0600-1400) before and after reconstruction in an NICU located in north central Florida.ResultsLevels before reconstruction were Leq M = 60.44 dB, L10 M = 59.26 dB, and Lmax M = 78.39 dB. The average overall sound levels after reconstruction were Leq M = 56.4 dB, L10 M = 60.6 dB, and LmaxM = 90.6 dB. Although an approximate 4-decibel decrease in the Leq sound level after reconstruction was noted, a similar decrease in the L10 and Lmax did not occur. Furthermore, sound levels after reconstruction in the NICU still exceeded recommended levels (Leq < 50 dB, L10 < 55 dB, and Lmax < 70 dB).Clinical ImplicationsFindings from this study demonstrated the positive impact that reconstruction can have on sound levels (4 dB Leq decrease); however, additional interventions may be needed to meet the current standards for noise reduction in an NICU.
