Acoustical
Buildings
ATCO Noise Management
offers extensive experience in the design, supply and erection of
acoustical buildings.  Our engineers prepare a noise diagnostic and utilize their extensive
project and pricing experience to deliver the most cost-effective
acoustical treatment for the proposed or existing facility. Treatments
may include:
- acoustical
envelope (walls and roof made from pre-fabricated acoustical panels
or constructed "in-situ")
- acoustical
equipment enclosures
- acoustical
ventilation systems
- custom designed
silencers (ventilation, gas turbine intake and exhaust, reciprocating
engine exhaust, heat recovery steam generator [HRSG])
- acoustical
personnel and equipment doors
- acoustical
windows and translucent panels
- acoustical
barriers
- decoupled
acoustical lagging
- other silencing,
such as acoustical louvers, plenums, ridge vents, etc.
Applications
A building may
need acoustical treatment when inside equipment emits noise beyond
required levels. Manufacturers may supply equipment with enclosures
designed to meet 75 dBA, 85 dBA or even 90 dBA at one meter (3 feet),
based on the project specifications. The attenuation level of these
standard enclosures sometimes is insufficient, particularly when
multiple noise sources exist inside a building, or if the building
is "reverberant". Customized, highly acoustical enclosures offered
by ATCO Noise Management and/or the acoustical treatment of the
entire building is the answer.
Acoustical
Envelope
We call an attenuated
building's walls and roof "the acoustical envelope." For
the envelope, mass law theory applies so that thick, dense walls
attenuate best. Few walls behave exactly according to mass law  where
sound transmission through the structure is proportional to the
weight and stiffness of the walls and roof. This is because walls
aren't static but move, causing vibrations. A building's envelope
needs to be constructed from materials that both absorb and block
sound while reducing vibrations. These materials are acoustical
(sound-absorbing) materials, barrier (sound-blocking materials),
damping materials, and vibration isolators that comprise our Noise
ManagementT assemblies.
Noise Leakage
Building openings
radiate huge amounts of noise. To reduce the amount of interior
noise "leaking" from building openings, ATCO Noise Management provides:
- custom designed
silencers
- acoustical
doors
- acoustical
windows
- acoustical
louvers
- acoustically
lined ridge vents
- acoustically
lined weather hoods
- acoustical
plenums
The building
is made airtight. Special seals and sealant block noise along joints,
penetrations, doors and windows.
