Select by Performance – Learn More: Acoustics
 |
Acoustical performance embraces two important areas:
- Sound Absorption (Alpha w): a measure of a material’s ability not to reflect sound,
- and Sound Reduction (R or Rw) which describes how much sound is reduced when it transmits through a material.
|
| For suspended ceilings Sound Reduction also includes Sound Attenuation (Dnc or Dncw), which is the process when sound transmits through the ceiling twice via the common ceiling void.
|
| Therefore, ceilings should be chosen depending on the actual acoustic requirements of a room or space. Armstrong offers an
extensive choice of acoustical ceiling solutions that will meet your project needs.
