论文摘要
医院噪音水平的持续增加已成为社会的至关重要的挑战。医院中的复杂音景会产生令人不愉快的噪音，这可能超过患者和医疗保健专业人员的规定噪音水平。先前的研究报告说，大声暴露于大声噪音可能会导致医疗保健专业人员，医务人员和患者的听觉和非听力障碍。因此，对医院场所的有效噪声障碍的设计和制造引起了人们的兴趣。本文中，我们对PVC涂层聚酯织物和100％纯PVC纸的声学性能进行了彻底的实验研究。这些潜在的声音窗帘的表演已经发现，医院现有声窗帘的表现优于现有声学窗帘。此外，结果表明，PVC窗帘的声音传输类别比现有的商业声音窗帘高得多。
The continuous increase of hospital noise levels has become a vital challenge for society. The complex soundscapes in the hospital produce unpleasant noise, which may exceed the prescribed noise level for the patients and healthcare professionals. Previous studies have reported that extended exposure to loud noise may cause auditory and nonauditory disorders in healthcare professionals, medical staff, and patients. Therefore, there is an increased interest for the design and fabrication of effective noise barriers for the hospital premises. Herein, we have performed the thorough experimental investigations on the acoustical performances for PVC coated polyester fabrics and 100 % pure PVC sheets. The performances of these potential acoustic curtains have found to be superior to that of existing acoustic curtains for hospitals. Also, the results showed that the sound transmission class rating of PVC curtains are much higher than the existing commercial acoustic curtains.
