2. Sound treatment is a key design consideration for almost every building, regardless of industry, in order to
reduce noise disturbance and enhance sound quality and selecting acoustic flooring materials is crucial to
effective sound treatment.
When noise is made within your building, it will either be absorbed, reflected or transmitted by your wall,
ceiling and flooring.The goal of sound treatment is twofold: (1) prevent transmission of sound from room to
room and floor to floor, and (2) reduce background noise to enhance the quality of speech or music within
rooms. Installing acoustic flooring is an effective and efficient way of accomplishing the former goal.
Acoustic flooring is effective at preventing the transmission of sound from an upper floor to a lower floor.
Types of noise acoustic flooring can help with
In general, acoustic flooring must prevent the transmission of two types of noise:
● Impact sound
Whether from foot traffic, carts or vibrating machinery, floors bear the brunt of impact within your
building.
● Airborne sound
Airborne sound typically stems from people, speakers and instruments. Like impact sound,
airborne sound can transmit through your flooring into other parts of your building.
3. 1. Carpet
Carpet is known for mitigating impact sound, making it a perfect choice for hotels,
classrooms and offices. Higher pile carpets or carpets with a thick pad underneath, are
especially good at absorbing sound and reducing transmission.
2. Cork flooring
Cork flooring is a sustainable, comfortable and sound-absorbent flooring option perfect
for many commercial applications. Still, due to its tendency to stain and indent it is
often used as an underlay to provide acoustic insulation.
3. Wood Plastic Composite (WPC) flooring
Durable, waterproof and easy to maintain, WPC flooring provides great acoustic
benefits, especially when it comes to mitigating the impact noise such as high foot
traffic. Its acoustic benefits are largely drawn from its backing layer, which not only
provides sound insulation, but also protects against mold and mildew.
4. Rubber flooring
Commercial rubber flooring is known for its sound absorbent qualities. More than that,
it is slip-, mold- and mildew-resistant. It is a great choice for hospitals, schools, gyms
and kitchens looking for a durable acoustic flooring material.
5. Vinyl tile
Vinyl tile, especially luxury vinyl tile (LVT) installed with a sound-insulating
underlayment, is a great resilient flooring option used for sound treatment. It is
selected by many facilities due to its design versatility, durability and relatively low
maintenance costs.

8. A suspended acoustic ceiling is a secondary ceiling, hung below the structural
ceiling both to treat room acoustics and to look attractive. Suspended ceilings have
the added advantage of hiding the mechanical, electrical, and plumbing
installations from view while maintaining some level of access to these utilities.
Suspended acoustic ceilings, then, are installed for one purpose, or a combination
of acoustical purposes (here slightly oversimplified).
1. Sound absorption: Wave energy is taken in when an absorbing
material encounters sound; part of the energy is transformed into heat
and part of it is transmitted through the material.
2. Sound reflection: Wave energy bounces back when it strikes a
material; part of the energy bounces back directly and part of it
indirectly as reverberation.
3. Sound diffusion: Wave energy bounces back evenly in a room. In a
perfectly diffusive sound, space reverberation times are the same at
any listening position.
9. MATERIALS USED FOR SUSPENDED ACOUSTIC CEILINGS:
1.Mineral Fibers typically sell as fissured suspended ceiling tiles.They are the entry-level
product in terms of price and performance and remain the most mass-produced type of
suspended acoustic ceiling product.They are perfectly suitable for many environments,
including offices and retail spaces.They are made from a blend of mineral fibers, perlite, clay,
and even recycled newsprint.
2.Faced Fiberglass panels come in a variety of products.
● Polyurethane or PVC bagged fiberglass is sometimes used directly as “faces,”
though rarely for public spaces.They are most often placed behind, in the role of
absorptive “body.”
● Woven fabric is wrapped around rigid fiberglass panels and offers designers a
rich color pallet.
● Painted PVC faced fiberglass (known as Nubby) and latex faced fiberglass
simulate the look of painted drywall.
● Special acoustic plasters are also used to face fiberglass panels. Once installed,
the panel edges are filled and coated with acoustic plaster.The effect is a drywall
or plaster look, but with acoustic properties.
3.Metal: Metals used in ceilings are typically aluminum, with a big effort put into recycling.
Panned ceilings are made of tin and other alloys.
10. 4. Wood: Wood gives designers hundreds of species to select from, though less
than 100 are used commercially—and of those, less than 20 are used regularly
in commercial ceilings.
5.Specialty Materials
● Cementitious wood fiber: Fine wood fibers cemented together
into an aerated acoustic pad.
● Reinforced Gypsum tiles (GFRG): Like wood or metal, the density
of Glass Fiber Reinforced Gypsum requires holes to make them.
● Polyethylene felts: Made from recycled bottles, these plastic felts
share the acoustics of fiberglass, and come in a variety of colors.
● PVC stretch materials: These elastic films stretch across a bay or
an entire ceiling. Fiberglass can be placed behind to improve
acoustics, or the PVC films can be micro-perforated.
● Acoustic foams: Made of urethane and melamine plastics, open
and closed cell construction provides acousticians different sound
attenuation properties. Some can be painted.
