Acoustic design of wall, ceiling, and plenum for college buildings

What can you do when an owner wants to design and build flexible learning spaces that can be reconfigured as the needs of the school teaching program changes? Well, we have done a research program on this issue and will share both laboratory and field testing data. Demountable wall systems, raised floors, deep ceiling plenums, stuff you stuff into the plenum, and high CAC ceiling tile. Does it make a difference if the teaching is live voice, recorded voice program, or how about music? Of course, it does. So let us talk sound transmission through the ceiling plenum and what to do about it.
