Scope:
Controlling environmental noise and
designing elements for architectural
and engineering acoustics, including
noise transmission from music and mechanical
spaces to more sensitive learning spaces.
Challenges: The school is located along
SR 9 in Arlington. While this
location provides excellent community
access, there is significant noise from
the highway along the eastern property
line. We needed to develop a cost-effective
solution to prevent excessive noise
while allowing traffic to move in and
out of the facility.
Solutions: An environmental
noise assessment was completed to determine
the impact that noise from the highway
would have on the new school. Environmental
noise monitors and ENM software were
used to document noise levels and determine
sound propagation. We designed
a berm/barrier wall with an opening
for traffic to reduce noise from the
highway. To reduce costs, the
berm was built using existing dirt rather
than importing it to the site. Our
recommendations included the berm, barrier,
Additional Work: Architectural
and engineering acoustic design recommendations
were also provided. Sound quality in
the commons was evaluated for music
and drama. Classrooms were designed
to achieve a NC35. The library,
gym, and the music room were designed
with the proper room absorption, reflection,
and diffusion.
