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.
