Abstract

The knowledge of the neonate's saund environment in incubators has the aim to better define the ways to protect neonates of nose effects and to improve their acoustic comfort The present study, realized in 9 hospitals, constitutes a sound database at 216 hows of recording made and outside of neonate's compartments, allowing valid statistical analysis end characterisation. The statistical index analysis of sound data shows that continuous noises are generally higher inside of incubators (50 ± 3 dBA) than outside (42 ± 8 dB A) Thar origins are mainly the incubator itself and the external medical devices sometimes used Or the contrary impulsive noises are far more frequent. and intense outside ot the incubator than inside Most of these noises come from the hospital activity for 88% of the time and are essentially produced by medical staff and nurses Furthermore. 25 incubators witnout neonate are evaluated with respect to the NF EN 60601-2-19 standard. Among these incubators, one is out of standard tor the internal level, an other is also out of standard for the internal alam sound, white all tested incubators are out of standard for alarm sound perceived outside. The protection of neonates and the improvement at their acoustic comfort can be achieved by instrumental, human and architectural proposals .

医院培养箱中婴儿的声音环境
本研究在9家医院开展,建立了216种录音方式和新生儿室外录音方式的声音数据库,允许有效的统计分析和表征。对声音数据的统计指标分析表明,恒温箱内的连续噪声(50±3 dBA)普遍高于体外的连续噪声(42±8 dBA),其来源主要是恒温箱本身和有时使用的外部医疗器械,反之,脉冲噪声则更为频繁。这些噪音88%的时间来自医院的活动,主要是由医务人员和护士产生的。此外,根据NF EN 60601-2-19标准对25个新生儿进行了评估。在这些孵化器中,一个内部水平不符合标准,另一个内部报警声音也不符合标准,白色所有被测试的孵化器都不符合外部感知的报警声音标准。新生儿的保护和改善他们的声学舒适度可以通过仪器,人类和建筑的建议来实现。
