Scope
The
community of Arlington has traditionally
relied on the High School Theater for
performing arts. With the plans
for a new high school, plans were made
to develop a separate 700 seat performing
arts center that could be used by both
the school and the community. We
provided design for interior shaping,
absorption, diffusion, and reflective
elements in the space to achieve an
environment for drama, music and choir.
Challenges
As
with all performing arts spaces, noise
from air-conditioning and heating systems
can be intrusive during performances.
A detailed evaluation was completed
to limit noise from these sources, and
our solutions were designed to meet
a noise criteria (NC) 30. Using sound
data for the selected air-handling units,
we were able to develop specific recommendations
to augment the mechanical design. These
recommendations were developed using
algorithms established by ASHRAE to
model sound within HVAC systems. The
finished product is a quiet system.
Solutions
Working
closely with the McGranahan team and
the Theater Designer, we created a 3-D
model capable of predicting the finished
qualities of the planned treatments.
By developing this model, materials
can be substituted, the shape can be
changed, and speakers can be tested,
and all prior to construction. This
allows for a uniform diffuse field of
sound within the space allowing the
most efficient use of the budget.
