Abstract
Exemplary baffles for inhibiting noise transmission through a pillar structure, and exemplary methods of making the same, are disclosed. An exemplary baffle may include a body configured to be secured in a cavity, the body defining a passage for selectively receiving a line extending through the body. The baffle may further include an expandable material extending substantially about a perimeter of the passage. The expandable material may be configured to expand to seal the cavity about the body. The body may include a flap configured to open to allow the line to extend through the passage. The body may further include a biasing element urging the flap toward a closed position, substantially obstructing the passageway.
