===Acoustics===
A unique feature found in no other multi-purpose arena is known as the "acoustical cloud". The acoustical cloud is a set of 160 rotating acoustic panels suspended from the Moda Center ceiling, intended to recreate the roar of noise that made the old Memorial Coliseum one of the loudest buildings in the NBA. One side of each 10&nbsp;feet&nbsp;by&nbsp;10&nbsp;feet (3&nbsp;m&nbsp;by&nbsp;3&nbsp;m) panel reflects sound, while the other side absorbs sound. Each panel is shaped like an airplane wing, and is 8&nbsp;inches&nbsp;(20&nbsp;cm) thick at the center and 4&nbsp;inches&nbsp;(10&nbsp;cm) thick at the edges. The effect during Blazers games is to absorb the noise from the upper levels and reflect it back down to the court.

The panels permit the acoustics of the arena to be adjusted according to the requirements of the event. For smaller events in which only the lower bowl of the arena is used, the panels can be lowered to further improve the sound and increase the intimacy of the arena. The acoustical cloud cost US$2&nbsp;million to design and install.<ref name="acoustics">{{cite journal|url=http://www.panstadia.com/vol3/32-022.htm|title=Creating an atmosphere|journal=PanStadia |volume=3|issue=2|access-date=October 29, 2007|url-status=dead|archive-url=https://web.archive.org/web/20071103044508/http://www.panstadia.com/vol3/32-022.htm|archive-date=November 3, 2007}}</ref> The arena is also equipped with a [[JBL (company)|JBL]] sound system.<ref name="facelift"/>
