Movable Acoustic Wall shall be as per the below details supplied by OZONE and shall consist of top-hung, manually operated Acoustic Panels that can be linked together to form an acoustic wall.

PANELS: Based on the requirement the panels shall be constructed of board separated by acoustic insulation to achieve the specified sound rating. Panel Faces are replaceable at the site.

ACOUSTICS: Acoustic walls are classified by an STC (Sound Transmission Class) rating for their effectiveness in reducing transmitted sound. Based on Acoustic Requirements the panels shall be of STC 45 or STC 52. STC 45 shall make the wall with loud speech barely audible on the other side & STC 52 shall make the wall with shouting barely audible on the other side.

CLOSURE: The movable acoustic wall shall be acoustically opened & closed with the help of an expanding panel located at the stacking end of the system. There is on over-sleeve on the expanding panel which can be expanded side ways to lock the acoustic wall in place. The oversleeve is expanded and retracted by a removable handle in the face of the pane.

STACKING: While opening of movable acoustic wall, panels shall be parked in a side stack configuration which means that single panels are hung at two points at the top corners of each panel. Panels will stack with one point remaining on the main track and the other on the side track.

SEALS: There shall be swept seals at the top of the panels to seal them acoustically to the track. There shall be retractable seals at the bottom of the panels to seal them acoustically to the floor.
