| Design and Acoustical Approach |
To meet Intelligibility, Confidentiality or Concentration needs, Armstrong recommends a 2-Step Design Approach for specifying
the correct ceiling for your acoustic comfort & health.
PASSIVE ACOUSTICS
First, consider Passive acoustic solutions to absorb sound within a space, and block sound transmitting between spaces, dividers,
or from outside the building.
Sound absorption is the part of incident sound that is not reflected by the tile.
Sound attenuation is the control of sound transmission between adjacent spaces with a common void above them.
Sound reduction is the control of sound generated in the plenum or coming from the floor above.
ACTIVE ACOUSTICS
To complement your passive acoustics design and enhance Intelligibility, Concentration and Confidentiality, consider using
active acoustics to:
- Reinforce Speech, by increasing the signal-to-noise ratio for improved intelligibility
- Mask sound to overcome “occupational factors”
- Provide intelligible public announcements
- Play music to create the appropriate atmosphere in a shop or waiting area
Armstrong’s i-Ceilings Sound Panels provide the active acoustics to complement the passive treatment wherever necessary.
