Valley
Covenant Church in Eugene, Oregon utilizes ASC Half Round
TubeTraps for rear wall and ceiling sound control. The system
is beautifully color coordinated for aesthetics and voiced for great
intelligibility. ASC installed this project over 15 years ago, and
they're still as good as new. Typically, ASC now uses SoundPlanks
to lower RT-60 and control directional sound reflection. The SoundPlanks
are are used as a cost effective alternative to TubeTraps.
However,
the ASC approach has always been to retain first reflections (brightness),
while controlling subsequent reflections (RT-60). Pastor Steve also
did the right thing by installing carpet and upholstered seating
in his Sanctuary, which originally didn't have these features. Overall,
he's very happy with the acoustic balance between spoken word intelligibility
and congregational singing.
Each
side of the Sanctuary ceiling features ASC's trademark "ribbed"
grid of acoustic absorbers. These act to slow down horizontally
directional reflections that can cause sonic "blurring"
during sermons and other spoken word events.
