The materials used for reducing the reflection of sound waves in
buildings are called Sound absorbing materials.
There are many materials which may be used for reducing the sounds
effects and also in buildings to reduce noise pollution.
Examples of these materials are following
1) Perforated card boards
2) Porous materials
3) Heavy curtains
4) Maps
5) Pictures put upon the walls
6) Carpets on the floors
7) Wood-wool Acoustic Panel
8) Moss Panels
9) Fabric Acoustic Panels
10) Cloth papers
11) Ceiling Baffle
12) Printed Acoustic Panels
13) Fiber boards
14) Porous plaster
15) Oil Cloth
16) Glass Silk
17) Porous Plastics
18) Sound Absorbing Foam (Pro Studio Acoustics Tiles)
19) Acoustic Panels (ATS
Acoustics)
20) Acoustic Curtains (Utopia Thermal Blackout Curtains)
21) Moving Blankets (Sure Max Heavy Duty).
22) Door Sealing Gasket
& Sweep Kit.
These materials suitably
applied to walls ,ceiling and floor of a room or Hall to reduce reflection of
sound waves from their surfaces. Sound absorbing materials should be porous ,inelastic
ally flexible, compressible or they may be having combination of two or more of
these properties.
The absorbent co-efficient
of commercial sound absorbing materials can be increased by various means such
as perforating ,slotting or by providing small apertures into the body of
materials , by doing so energy centre of sound dispersed sideways.
Architectural Soundproofing . This includes everything used in the structure of a
building, such as soundproof windows, soundproof walls, doors, and decoupling
products used to install them.
