目的为了确定声激活噪声计提供直接审计和视觉反馈是否可以降低3级新生儿重症监护室（NICU）的声级。在噪声测量仪存在但没有视觉信号波动的情况下，持续2个月，随后噪声测量仪提供直接审计和视觉反馈。在所有患者护理区域中，NICU中声级低于50 dB的时间百分比（9.9%，8.9%和7.3%）。在没有住院病人的办公桌区域没有观察到这种改善。有没有变化的时间NICU低于45或55 dB的百分比。结论声激活噪声计似乎有效地降低了病人护理区的声级。对话可能已经转移到非病人护理领域，防止类似的变化。
Objectives To determine if sound-activated noise meters providing direct audit and visual feedback can reduce sound levels in a level 3 neonatal intensive care unit (NICU).Design/methods Sound levels (in dB) were compared between a 2-month period with noise meters present but without visual signal fluctuation and a subsequent 2 months with the noise meters providing direct audit and visual feedback.Results There was a significant increase in the percentage of time the sound level in the NICU was below 50 dB across all patient care areas (9.9%, 8.9% and 7.3%). This improvement was not observed in the desk area where there are no admitted patients. There was no change in the percentage of time the NICU was below 45 or 55 dB.Conclusions Sound-activated noise meters seem effective in reducing sound levels in patient care areas. Conversations may have moved to non-patient care areas preventing a similar change there.
