buildings and new noise -sensitive non-residential buildings, as defined herein, that are
located wholly or partially within the boundaries of the 65 DNL or greater noise contours
as designated in Figure L 1212.1(1).
The term "new" shall apply to new detached buildings built after the effective date of
this ordinance, and shall include later additions or modifications to those same buildings.
The term shall also include a Change of Occupancy in existing buildings from a non -
protected occupancy to one of the protected occupancies listed herein.
Buildings in existence prior to the effective date, and additions to or modifications of
those same buildings, shall not be required to comply, except when a Change of Occupancy
from a non -protected occupancy to one of the protected uses is involved.
SECTION L1213
DEFINITIONS
L1213.1 General. The following words and terms shall, for the purposes of this
chapter and as used elsewhere in this code, have the meanings shown herein.
Aircraft noise — is generally expressed in terms of it's A -weighted sound level, in units
called "decibels." Strictly speaking, the decibel unit should be abbreviated only by "dB";
however, for clarity "dBA" and "dB(A)" are often used to highlight the fact that the sound
level measurement has been A -weighted.
Noise exposure — in areas around airports is expressed in terms of the Day -Night Average
Sound Level, which is abbreviated by "DNL" in text and "Ld,," in equations.
NOISE -SENSITIVE NON-RESIDENTIAL BUILDINGS —
1. Nursing homes and hospitals, generally classified as Group I; and
2. Child day care centers, Adult day care centers and schools, generally classified as
Group E and Group I-4.
RESIDENTIAL STRUCTURES: Single-family, Two-family, Townhouse, Multi-
family, and Assisted Living uses, generally classified as Group R, whether in a single
occupancy or mixed occupancy.
Sound insulation properties — of building construction materials are described by Sound
Transmission Loss (TL) or Sound Transmission Class (STC). The higher the TL or STC
value, the less sound will be transmitted through the building material.
SECTION L1214
PURPOSE
L1214.1 General. All buildings and structures with protective uses, as applicable
under this Division, shall be required to have minimum sound insulation standards and

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.
,a
%W61- 1-->
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,

Figure 2-2. Sound Transmission paths Into Dwelling Interiors
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.
97
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 materialr6ndhave
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.

Roof vents
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.
