Acoustical Treatment Installation
at Municipal Auditorium in
Kansas City, MO
Echo Eliminator™ Bonded Acoustical
Cotton (BAC) Hanging Baffles
The acoustical treatment installation at Municipal Auditorium
included 30 Acoustical Assemblies, each consisting of five
4' x 8' x 2" white bonded cotton panels attached to a
21' aluminum ladder truss and hung from rigging points
above the ceiling.
Each panel had 3 grommets installed at the top. A 1/16" wire
rope loop attached the panel to the truss. The truss was
attached to the steel structure above the ceiling with 3/16" wire rope rigging harnesses. The circular penetrations that the
rigging harness passed through were already in the
ceiling.
The acoustical treatment of Bonded Acoustic Cotton (Echo
Eliminator™) accomplished what it was designed to do. It dropped the reverb time in the space nearly 2-1/2 seconds
to get to an excellent speech intelligibility in this large venue.
BAC is a high performance acoustical absorber that is
Class A-1 ASTM E-84, Non-Flammable. BAC is also
recycled/recyclable LEED approved, very inexpensive,
attractive, easy to work with, lightweight and durable.
