28
Define infiltration.
Infiltration is uncontrolled inward air leakage to conditioned spaces through unintentional opening in ceilings, floors, and walls from unconditioned spaces or the outdoors caused by the same pressure differences that induce exfiltration.

32
Define reverberation.
Reverberation is an acoustical phenomenon that occurs when sound persists in an enclosed space because of its repeated reflection or scattering upon the enclosing surfaces within the space.
33
The objective of the SMACNA guidelines is to \_\_\_\_\_.
protect the indoor air quality of buildings that are under construction through measures such as housekeeping, scheduling, source control and HVAC protection
34
\_\_\_\_\_ involves health and comfort effects linked to time spent in a building, but where no specific illness or cause can be identified.
