The Architectural Sound Traps
are cylindrical sound absorbers based on ASC's patented bass trap
(the TubeTrap™) technology. This unit is 9" diameter and
36" long. It can be attached at both ends and strung together
on cables vertically or horizontally. There is a rigid threaded
center rod connecting the two ends. The core is supported with bulkheads
which compartmentalizes the otherwise hollow tube. This model (shown
below) does not have an exoskeleton welded mesh screen as our standard
units have, therefore it is structurally not as strong. It is covered
with a thick gray felt-like fabric, or any of our fire rated Foss
fabrics for a small upcharge.
It
has an absorption coefficient of 1.5 in the speech range of 250
Hz and above. This means it provides 10.0 Sabines per unit in the
NRC range. You can estimate the NRC of the acoustic cloud by dividing
the absorption by the area per tube. For example a single layer
of tubes, on 8' centers, provides:
NRC = 100% x 10Sabines/8x8sqft
= 15% at a cost of about $1.50/sqft.
They offer broad-band noise
control as well as flexible installation for large volume space.
