| | Hoffend & Sons, Inc. Rose Garden Arena Rigging Case Study (Site not responding. Last check: 2007-11-06) |
 | | The owner of the NBA Portland Trailblazers, Paul Allen of Microsoft, desired mechanically-enhanced, variable acoustics in the arena to achieve noise dampening (echo avoidance) for rock concerts, as well as enhancement of crowd noise for basketball games. |
 | | Hoffend and Sons, Inc. delivered, by designing, manufacturing and installing 160 movable acoustical panels that cover the interior ceiling of the arena, effectively allowing the raising and lowering of the ceiling. |
 | | In addition, the rows of 10 x 8 panels can be rotated 340 degrees to change from the hard, convex surface to a sound absorbing surface, or be individually tilted to any degree. |
