Def initions
Like most specialized fields, the science of acoustics has a language
all its own. Some of the most important terms and concepts to be familiar
with include:
Absorption Percentage of sound waves that a material transforms into heat energy antl thereby does not reflect back into the space.
Ar#icula#ion index (AI} A measurement of how well speech can be understood in a space. High AI is desirable in spaces such as auditoriums
and theaters and can be achieved with a combination of materials antl design details that strategically reflect and
absorb sound. Reduced AI is desirable for spaces such as open offices, where many people must work fndependently,
and in financial and heaithcare facilities, which are subject to federal privacy rules; sound masking can be used to
� reduce AI (see the next page for more information).
Ceiiing Attenoatian A measurement of the ability of a ceiling panel to block the travel of sountl from an enclosetl room up into the plenum
Ciass (CAC) and tlown to atljacent spaces. High-CAC ceiling panels can provitle this type of sound control, increasing speech
� privacy in private spaces and retlucing distractions to those outsitle.
Gonductivity The ability of a material to iransmit sound waves. In addition to moving through air, sound waves can travel even more
easily through many solid objects. For example, sound waves move through air p0 '� at just 1,128 feet per second
but iravel about 10 times faster (11,700 feet per secon� through wood, and faster stiil (18,000 feet per secon� through
� steel. Therefore, designers must consitler not only airbome sound, such as voices and ringing telephones, but also
structure-borne sound created by footfall, doors opening and closing, antl building systems such as elevator machinery
and FIVAC equipment.
Diffracfian The bending of sound waves around objects or through small spaces and openings with little energy loss. Spaces
around doors, floor tracks, electricai boxes, and conduit antl HVAC ducting are typical channels for sound diffraction.
These spaces should be filled with acoustical sealar� to prevent unwanted sound from inVuding into adjacent spaces.
Flanking Paihs Smali gaps and openings around doors, floor tracks, electrical boxes, and conduit and HVAC ducting that allow sound
to pass through 'rf not filled with acoustical sealant. Also called "leaking paths."
Impact isolation Measurement of the ability of a floodceiling assembly to isolate sound from footfall arid other impact sources,
Cfass ([IC) reducing the inVusion of noise into rooms directly below.
Noise Reduction Measurement of the ability of a material such as an acoustical ceiling panel to absorb sound energy in the frequency
Coefficient (NRC} range of 250 Hz to 2,000 Hz (see °pitch" for more information). High-NRC ceiling panels provitle this type of sound
control, which is important for large spaces such as open-pian offices.

Definitions
Pitch The oscillation rate of a sound wave, which traveis as a small pressure change alternating above and below the static
(at rest) state of the conducting material. Each cycle of compression and re-expansion is a wave. The number of
waves occurring per second is the frequency, which is measured as hertz (Hz); one Hz equals one cycle per second.
A sound's pitch rises as its frequency increases. The human ear can discern sounds ranging from approximately
20 Hz to 20,000 Hz. Numan speech ranges beiween 125 Hz antl 4,000 Hz:
Reflectian The bouncing of sound waves off any hard, smooth wall, ceiling or floor surface, making them audible beyond the
immediate area of the source. The shape of surfaces aiso affects where sound may travel. Concave surfaces
concerrtrate or focus sound, while convex surfaces can disperse sound in multiple directions.
Reverberation Sound that persists in an enclosed space by reflecting off surtaces in the room.
Sound Masking A carefully engineered sound spectrum similar to that of soitly blowing air, which is amplified through speakers to raise
the ambient sound level, "masking" conversations and backgrountl noise. In enclosetl rooms, sound masking increases
speech privacy by lowering the articulation index, preventing conversations from being overheard.
Soand Transm9ssion Measuremer� of the ability�of a wall or floor assembly to isolate airborne sound and prevent it from passing from one
Ciass (57C) side to the other.
Transmission The passage of sound waves from its source, through a vibrating medium, and to a listener. "Airbome sound" passes
through a space by vibrating the air. "Structure-bome sound" travels through wall partitions, ceilings and floor/ceiling
assemblies.
Vniume The loutlness of a sound—how much the amplitude of a sound wave exceeds the static pressure of the conducting
medium—as measured in decibels (dB). The higher the decibel level, the greater the volume. Noise from a jet plane
has an amplitude of 140 d6, while a human whisper is approximately 20 dB. Sound in a typical office environment
reaches 40 dB to 60 d6. Volume doubies with each 10 dB increase in sountl energy.

Performance Testing
Testing provides a measurement of maximum performance potential
achieved under controlled laboratory conditions. The actual ability
of partitions and assemblies to control sound in real-life applications,
however, depends on their design and tlie methods used to install
them. Deviations from the detailing shown in this publication, substitution
of components, or damage and improper repair or mainteriance could
severely reduce the acoustical performance of these installations.
Testing Methods
All USG products and systems undergo exhaustive testing to ensure that they meet exacting stantlartls. USG's products
are Classified as to fire resistance and fire-hazard properties. As part of this protocol, Underwriters Laboratories (UL)
periodically autlits protluction of these materials to ensure compliance with necessary properties. UL is an independent,
not-for-profit organization that has tested products for public safety for over a century.
Products are manufactured and tested in accordance with recognized standards. ASTM International is one of.the
largest voluntary standards development organ¢ations in the worid, and is a trusted source for technical standards
for materials, products, systems, and services.
Testing Resuits ASTM C423
Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method measures Noise Retluction
Coefffcient (NRC). This rating represents the average of a given materiai's sound absorption coefficienis at four
frequencies ftom 250 Hz to 2000 Hz.
ASTM E1414
Determination of Sountl Transmission Class by the Two-Room Method measures Ceiling Attenuation Class (CAC), the
sound retluction in decibeis provided between rooms with a shared ceiling and common plenum. This rating represents
the average of the sound attenuation at four frequencies from 250 Hz to 2000 Hz.

Add sound insulation
Adding a layer of fibrous sound-absorbing insulation material such as mineral wool into the partition cavity will dissipate
sound by creating friction, which transforms a portion of sound wave energy into heat. However, sound attenuation
blankets cannot completely counter the conductivity of the wood or steel studs in the framing assembly, which provide
a path of least resistance for sound energy.
Decouple wall panels
Attaching the wall surtace diaphragm (e.g. drywall panels) directly to framing members provides an uninterrupted path
for sound travel. This route.can be interrupted by mounting the surface diaphragm to resilient channeis attached to
the walt stutls and placing sound insulation inside the partition cavfty.
Seal flanking paths
Closing off gaps or penetrations in the wall assembly is critical to controlling noise. One of the most effective methods is
to apply acoustical sealant at the intersection of the gypsum panel, floor system (wood or concrete), and the leg of the
steel runner or•wood sole plate; sealant shoultl be applied at this location on both sides of the partftion. A properly
sealed wall assembly with one 5/8" gypsum panel on each side and a 1-1/2" thick sound attenuation blanket installed
in the air cavity achfeves an STC of 53. Without acoustical sealant, this assembly would produce an STC of oniy 29—a
dramatic 45 percent retluction.
Increase isolation with steel studs
A single-layer partition with 5/8" gypsum panels and 3-5/8" stud achieves 40 STC with 25-ga. steei and 38 STC,with
20-ga. steel. STC falls to 35 with a tratlitional 2' x 4' stud due to the greater st'rffness of wood.
FloorlCeiling Assembiies Isolate sound
Whether constructetl with joists, trusses or concrete slabs, floor systems can develop gaps or cracks, providing a flanking
path for sound to travel between leveis of a building. Even properly sealed assemblies can transmit noise from footsteps,
falling objects, closing doors and other impacts. These acoustical problems can be signifiqntiy reduced with a flooring
- system that includes a layer of sound absorbing material topped with a poured cementitious untlerlayment. The poured
untlerlayment finds and seals cracks and other sound channeis, then hardens to form a solid barrier isolated from
the structure below by the sound mat or board. This system can provide 5TC ratings as high as 66 and increase IIC
by as much as 13 points, a significant improvement.
