Acoustic curtains, which are widely used in room acoustic projects, are a kind of fire resistance porous organic-fiber material with many. Good characters such as adjustable sound-absorption, easy installation, decoration effect, etc.. The absorption of curtains is affected by both the properties of the textile, such as density, thickness, and the conditions of fixing, such as the air space between the wall and the curtain, the frills, the extending areas. To further study the acoustic properties of acoustic curtains, a series of test were conducted with different conditions. In many room acoustic projects, for example the adjustable curtain in Shanghai Grand Theatre, the outer acoustic drop scene in Shanghai People’s Grand Stage and the hidden adjustable curtain in Guangxi Wuzhou Culture Center, acoustic curtains show a great advantage. This paper focuses on the acoustic performance of acoustic curtains through experiment measurements.
