Trap Club Noise Monitoring Page 7
For both the deck barrier and the property line barrier, they need to be solid and must be one
continuous barrier, with no holes, gaps or openings. For example, a wood fence with non-
airtight gaps between boards and a gap at the bottom of the fence would not be effective as
noise will leak through all openings.
Some material options for the deck barrier and property line barrier are wood (as long as all
boards are tight and flush with one another; no air gaps), metals (e.g. steel, aluminum,
stainless steel), masonry blocks (CMU), concrete, or stucco finished fence. The minimum
thickness of material used depends on the mass and weight of the material. If wood is used,
the minimum material thickness should be at least ¾” plywood/OSB, or the equivalent weight
of 2.35 pounds per square foot (psf). Any thinner or lighter, then there will be a noise
transmission issue through the barrier itself and the noise requirement may not be met at the
outdoor receivers.
As mentioned above, the deck barriers should be on the side of the deck facing the trap club.
For houses 4 through 10, this means that the north side of the deck should include a barrier.
For houses 1 through 3, the barrier will need to be on portions of the north and east sides of
the deck, so that the barrier blocks line of sight to the trap club from all locations on the deck.
The property line barrier should run from the west edge of house 2’s backyard to the east
edge of house 10’s backyard (shown with the red line in Figure 4 below). This length of
barrier will attenuate noise to all backyard receivers in the development, so that the
protection act requirement is met at each house.
