SOUND INSULATION REQUIREMENTS FOR NOISE
SENSITIVE USES NEAR AIRPORTS
SECTION AK101
GENERAL
AK101.1 Scope. The regulations and requirements shall apply to all new residential
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 AK101.1(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 AK102
DEFINITIONS
AK102.1 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 its A-weighted sound level, in units called
"decibels." Strictly speaking, the decibel unit should be abbreviated only by "dB"; however, for
clarity "dBA" and "M(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"Ldn"in equations.
Ordinance No.22519-12-2016
Page 44 of 79
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 AK104.5
Sound Waves
AK104.5 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.
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.

tow-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 materialrandhave
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 Y' approved semi-rigid sound insulation.

LOG NAME: 06ADOPT AND AMEND 2015 I-CODES
SUBJECT:
Adopt Ordinances Adopting and Amending the 2015 Editions of the International Building Code,
International Residential Code, International Mechanical Code, International Plumbing Code, International
Fuel Gas Code, International Existing Building Code, International Energy Conservation Code and the Fort
Worth Building Administrative Code and Adopt Ordinance Adopting the 2015 International Fire Code with
Local Amendments (ALL COUNCIL DISTRICTS)
RECOMMENDATION:
It is recommended that the City Council adopt the attached eight ordinances which include the following:
1. Adoption of the 2015 International Building Code with local amendments as the Building Code of the
City of Fort Worth;
2. Adoption of the 2015 International Residential Code with local amendments as the Residential Code of
the City of Fort Worth;
3. Adoption of the 2015 International Mechanical Code with local amendments as the Mechanical Code of
the City of Fort Worth;
4. Adoption of the 2015 International Plumbing Code and the 2015 International Fuel Gas Code with local
amendments as the Plumbing Code of the City of Fort Worth;
5. Adoption of the 2015 International Existing Building Code with local amendments as the Existing
Building Code of the City of Fort Worth;
6. Adoption of the 2015 International Energy Conservation Code with local amendments as the Energy
Code of the City of Fort Worth;
7. Adoption of the Fort Worth Building Administrative Code; and
8. Adoption of the 2015 Internal Fire Code and local amendments.
DISCUSSION:
The Fire and Planning and Development Departments have worked to consolidate and coordinate the
amendments in their respective Fire and Building Codes into a single action before the City Council. The
City of Fort Worth has adopted model codes from the International Code Council (ICC), with local
amendments, as the construction codes for the City since 2004. These model codes are reviewed and
updated annually through a national code adoption process. Every three years these changes are
Logname: 06ADOPT AND AMEND 2015 I-CODES Page 1 of 3
codified and published for local adoption. Fort Worth has historically adopted newly published Codes
every six years, most recently adopting the 2009 Codes in 2011. The 2015 edition of ICC codes are the
latest published version offered for adoption. The State of Texas has adopted the 2015 International
Energy Conservation Code (IECC) as the energy code for the State. Planning and Development staff
recommends adopting the 2015 International Codes as the construction codes for the City of Fort Worth.
Construction codes change with the development of new products, materials, construction methods,
technology and as a result of evaluations of natural and man-made disasters. Adoption of current codes
has a positive impact on the City's ISO rating.
The City of Fort Worth local amendments are based on the amendments recommended for regional
adoption by the North Central Texas Council of Governments and our local practices. A committee was
formed to review the City's local amendments including representatives from the Development Advisory
Committee, the Construction Fire Prevention Board of Appeals, the AIA, the Fort Worth Builders
Association, FWISD and TEXO the Association of General Contractors. The Development Advisory
Committee and the Construction Board of Appeals have been briefed on the proposed amendments. The
Construction and Fire Prevention Board of Appeals recommended approval of the adoption of the Codes
on November 11, 2016.
The construction code ordinances will have an effective date of January 1, 2017 for all provisions except
Section 423 of the International Building Code which will be effective April 1, 2017.
The attached ordinance for the Fire Department reflects transition of the Fort Worth Fire Code to the 2015
International Fire Code (IFC) with Local Amendments. All local amendments recommended for the 2015
IFC have been reviewed by the Fire and Planning & Development Departments and have met the
approval of the Construction and Fire Prevention Board of Appeals for recommended adoption at their
public hearing on November 11, 2016.
This action impacts ALL COUNCIL DISTRICTS.
This M&C does not request approval of a contract with a business entity.
FISCAL INFORMATION / CERTIFICATION:
The Director of Finance certifies that approval of these recommendations will have no material effect on
City funds.
