Panelok's perforated panels significantly reduce acoustic reverberation. The panels are backed first by acoustically transparent fabric, then a thick acoustic quilt. The absorption effect is further enhanced by a rear air void.
The proportion of perforated panels to plain panels is critical. Too little, and the reverberation won't be sufficiently reduced. Too much, and the lack of echo can be disconcerting. EESmith Contracts designs the appropriate level of acoustic engineering as part of our supply and fit package.
