ACOUSTIC on CONCRETE BLOCK |
|
 |
Fabric panel with plywood
shim secured to concrete substrate, with 1" fiberglass core.
Additional shims can be added
to incorporate 38mm (1.5") or 51mm (2") acoustic cores.

ACOUSTIC - LOW FREQUENCY |
|
 |
Fabric panel with 6 mil POLY
stretched taught over acoustic core -- not adhered.
Provides greater low frequency
attenuation.
* Shown using the 1/2" bullnose
trac. |

|
ACOUSTIC - LOW FREQUENCY |
|
 |
Fabric panel with 6 mil POLY
stretched taught over PVC extrusion frame.
No
contact with acoustic core.
Superior
low frequency attenuation.
*
Shown using the 1" bullnose trac. |
|
* 6 mil POLY has superior properties to act as a diaphram than
does vinyl fabric.
Glueing or adhering poly to acoustic core greatly reduces its
ability to act as a diaphram and control low frequency sound.
