The
Industrial 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 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.
We have modified the end caps
and surface finish to accommodate interior design interests which
boosts the cost a little. This is a versatile device and can be
modified to suit a variety of visual needs. The units pictured below
are our standard TubeTraps.
They offer broad-band noise
control as well as flexible installation for large volume space.
