An acoustic medium for temporary acoustic treatment of a room is formed from one or more continuous curtains, preferably, with pleated first and second major surfaces. Each pleated curtain preferably has one or more series of collapsible elongated tubular sections which form the pleats that make up the major surfaces of the curtain. Since the elongated tubular sections are collapsible, the curtain can be retracted by collapsing the elongated tubular sections and extended by opening the elongated tubular sections. The mat materials forming the elongated tubular sections and the pleated major surfaces of the curtain provide the curtain with an airflow resistance through the curtain, in a direction generally perpendicular to the planes containing the apexes of the pleats forming the first and second major surfaces of the curtain, that has the desired properties for absorbing or reflecting sound.
