Acoustical Ceiling Overview

Acoustic ceiling tiles are perfect for providing acoustical sound absorption for offices, healthcare, and educational facilities. Learn about the acoustic ceiling products recommended for each application and the acoustical properties of each product.


Acoustics is an integral factor of indoor environmental quality (IEQ), and it’s essential that surface finishes and systems be selected to enhance the functionality of any space relative to its design usage. Speech intelligibility is of obvious concern in classrooms, conference rooms, doctor’s offices, etc., and the choice of ceiling tile and acoustical wall treatment will have a significant effect on noise level and reverberation within these spaces. Speech privacy is likewise a real concern in hospitals, clinics, offices, etc., and the choice of ceiling and wall systems will have a significant impact on the sound intrusion between spaces.

In many cases, a sound absorbing material (ceiling or wall) will also have a significant sound attenuation effect, such that both aspects should be taken into consideration.


Acoustic Ceiling Tiles

Absorption
- Sound absorption is the part of the incident sound that is not reflected by the acoustical tile Attenuation
- Sound attenuation is the control of sound transmission between adjacent spaces with a common void above them by the use of acoustic ceiling tiles.
Reduction
- Sound Reduction is the use of acoustic ceilings to control sound generated in the plenum or coming from the floor above.

Whether the concern is speech or noise or sound quality, a combination of sound absorption (surface finishes), sound attenuation (walls, floor, ceiling barriers), and background noise will combine to determine the acoustic performance of the space.

Some spaces such as open offices will do well with a moderate level of background noise for privacy, whereas other spaces such as classrooms will do best with low levels of background noise for intelligibility.
