SECTION L1216
Sound Waves
L1216.1 General. The following are examples of compliance issues and methods.
Airplanes, jets and helicopters (aircraft) approach structures from different angles. It is not always from overhead. Low flying aircraft, as well as, take offs and landings will create sound waves that approach structures from all sides.
[image omitted; see the official code]
Sound waves are just that, waves. They travel out in a circular method from the producing object. They enter through openings and in a case like an attic, reverberate within the cavity. When the entry of such waves cannot be prevented such as with the installation of attic ventilation, dampening devices are needed to prevent the reverberation.
Figure 2-2 displays the three different major paths for noise transmission into a dwelling: air infiltration through gaps and cracks, secondary elements such as windows and doors, and primary building elements such as walls and the roof.
[image omitted; see the official code]
Low-frequency sound Is most efficiently transmitted through solid structural elements such as walls, roofs, doors, and windows. High frequencies travel best through the air gaps.
Within these broad categories, different building materials have different responses based on the frequency of the incident sound and varying abilities to insulate against sound.
∙ Ducts to the outside, whether intake or exhaust, and all ducts in the attic or crawl space can be lined with 1-inch acoustical internal lining material and have at least one 90-degree (right angle) elbows (turns) thereby breaking the line-of-sight to the outside as shown in Figure 3-6. It must be noted that there is concern than this fibrous acoustical lining material will affect air quality. Installing a duct sound attenuator (silencer) is an alternative to this technique; there are silencers available that do not contain fibrous lining. These measures ensure that the ventilation system is not bringing additional aircraft noise into the house.

Attic Insulation
When considering the upgrade of thermal insulation to reduce noise levels it is important to understand what the insulation will do. Thermal insulation materials will act to absorb sound that is reverberating in the attic or in the space between flat panels. It does not prevent noise from entering the space. That is, it has no appreciable acoustic "insulating" properties but acts as an absorbent instead.
[image omitted; see the official code]
[image omitted; see the official code]
When using roof vents, whether a ridge vent or a single vent, a trough should be constructed and hung from the joists. The trough should be as wide as possible to cover the area of the vent. For ridge vents, it is preferable that it extend from joists to joists, leaving enough room around the edges for the required amount of venting. For single vents, the trough should be installed at the appropriate angle to match the roof slope.
The trough should be as long as the roof vent, perhaps a few inches longer, and capped on the ends.
The inside of the trough should be lined with 1" approved semi-rigid sound insulation.
