Abstract
Certain oxygen therapy masks operating with a venturi were found to possess audible noise levels sufficient to cause annoyance to the user. This was not true of all masks. However, it is recommended that this is a source of noise pollution that should be eliminated by the manufacturers of such devices.
摘要
某些使用文丘里管的氧疗面罩被发现其噪音水平足以让使用者感到烦恼。并非所有面罩都是如此。然而，建议将此作为一种噪音污染源，应由此类设备的制造商予以消除。
