ABSTRACT:
Baffle formed with a plurality of molded elastomeric plates within a housing for lining the interior of sound-absorbing ventilators, each plate having a central aperture and grooves in the broad sides of the plates which extend from the aperture to the edge of the plate; the apertures form a channel when the plates are stacked within the housing and the grooves form canals from the channel to the outside of the stacked plates.
