The continuous increase of hospital noise levels has become a vital challengefor society. The complex soundscapes in the hospital produce unpleasant noise,which may exceed the prescribed noise level for the patients and healthcareprofessionals. Previous studies have reported that extended exposure to loudnoise may cause auditory and nonauditory disorders in healthcare professionals,medical staff, and patients. Therefore, there is an increased interest for thedesign and fabrication of effective noise barriers for the hospital premises.Herein, we have performed the thorough experimental investigations on theacoustical performances for PVC coated polyester fabrics and 100 % pure PVCsheets. The performances of these potential acoustic curtains have found to besuperior to that of existing acoustic curtains for hospitals. Also, the resultsshowed that the sound transmission class rating of PVC curtains are much higherthan the existing commercial acoustic curtains.
