 
It's common practice in today's office buildings to install acoustic
barriers in the ceiling plenum to stop noise transmission from one
office to another, via the cavity in the ceiling space.
A typical and more expensive method is using the stud and plasterboard
wall. The ceiling cavity is not an easy space to work in and its
normally cluttered with pipes, ducts, light fittings and ceiling
support metal work. It's very difficult to get 100& seal.
Made of a special barium - loaded vinyl material, Wavebar Sound
Baffle is very flexible and easy to install even in and around awkward
places - or drape - or join into mats and enclosures - to greatly
reduce noise transmission.
A variant, Wavebar Sound Baffle FL, is manufactered with an aluminium
finish.

Wavebar Sound Baffle ...
is easy
to cut and fabricate around pipe penetrations, ducting and cabling
boasts
high tensile strength
is highly
resistant to tearing
enables
unusually long vertical drops, providing an economical noise-barrier
system even when space is limited
comes in
weights of 2, 4 6, 8 and 10kg/m
in its
Wavebar Sound Baffle FL variant, is suited to joining with aluminium-reinforced
tape which can eliminate the need to use adhesives or mechanical
fastening.

Wavebar
Sound Baffle is ideal for:
shutting
traffic and aircraft noises out of offices and homes
portable
screens
use in
partioning
under floor
above false
ceilings
soft enclosures
for fans and machines
strip curtains
use as
a sound barrier against the noise of jack hammers, drill rigs, blasting
and pile drivers.
