Key facts and history
A dropped ceiling may be an inverse of a raised floor.[1] A concave or barrel-shaped ceiling is curved upward for visual or acoustical value.[1] A coffered ceiling is divided into a grid of recessed square or octagonal panels.[1] Joan Meyers‐Levy and Rui Zhu published research on ceiling height's influence in the Journal of Consumer Research in 2007.[3]

That paper has been cited by 284 works.[3] A cove ceiling is defined by a concave plaster molding that bridges the wall and ceiling surfaces.[1][2] Stretched ceilings consist of separate panels, often made from PVC, that attach to a rail around the room's perimeter.[1][2] The height of a ceiling, especially when it is low, can have psychological effects on people.[4][3]

What the research sources say
The 2011 book "Interior Graphic Standards", published by John Wiley & Sons, details various ceiling types and their construction methods.[2][1]
