For
large open plenum spaces such as the typical factory floor with
large machinery, noise can quickly build up beyond acceptable OSHA
limits.
This can be a serious safety issue, and the goal is to gain OSHA
compliance by lowering the noise floor. Suspending ASC
Industrial SoundTraps from the ceiling is one way to lower the noise
level.
Industrial SoundTraps
are cylindrical sound absorbers based on ASC's patented bass trap
(ASC-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 suspended SoundTraps, on 8'
centers, provides:
NRC = 100% x 10Sabines/8x8sqft
= 15% at a cost of about $1.50/sqft.
